首先附上源码,可以下载

在建立导航菜单的时候,我们首先布局一个(" 头"+【左,右(自适应)】+”尾“)的HTML页面;

来看一下HTML页面的编写:

<div id="container">
        <div id="head"></div>
        <div id="mainContent">
            <div id="sidebar"></div>
            <div id="content"></div>
        </div>
        <div id="footer"></div>
    </div>

这个是代码布局的样式具体请看全部HTML:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>五种常用的导航菜单</title>
<!-- 
    @头部:一级导航菜单
    @尾部:二级导航菜单
    @左侧:树状导航菜单
    @右侧靠左:悬浮式导航菜单
    @右侧靠右:手风琴式导航菜单

</head>
<body>
    <div id="container"> <!--这是一个整个页面包含的祖先级div -->
        <div id="header">this is a header use to put level one navigation menu</div><!--这个是头部的一个div,如果把中间的左右看成一块的话,就有三层这是第一层-->
        <div id="mainContent"><!--这是第二层,第二层又包含左右两个子div-->
            <div id="sidebar">this is a side bar use to put multileve tree navigation menu</div><!--这是左侧div-->
            <div id="content">this ia a content :the content left suspension(rig  or left ) navigation,right accordion style navigation menu</div><!--这是右侧div-->
        </div>
        <div id="footer">this is a footer use to put level two navigation menu</div><!--这是第三层-->
    </div>
</body>
</html>

 下面我们来看看怎么把它布局成(" 头"+【左,右(自适应)】+”尾“)的形式,问我们通过css样式来控制,建立css样式文件ethanNavMenu.css,把它引入到HTML中

来看一下CSS布局样式:

body{font-family:Verdana;font-size:12px;margin:0;}
/*这个就没有什么好解释的了*/
#container{margin:0 auto;width:100%;}
#header{height:40px;background:#9c6;margin-bottom:5px; text-align:center;}
#mainContent{height:600px;margin-bottom:5px;}
#sidebar{float:left;height:600px;width:300px;background:#c9f;}
#content{margin-left:305px !important; margin-left:302px;height:600px;background:LavenderBlush; }
#footer{height:200px;background:#9c6;}

好了,整个页面布局就弄好了,然后我们来写导航;

 

下面代码中myalert()是原生自定义弹出框,turnUrl()是自定义跳转函数,代码稍后附出

(一)首先,我们来看”一级导航“的实现:

第一步:我们在HTML的id="header"的div中添加如下代码:

下面代码中myalert()是原生自定义弹出框,代码稍后附出。

     <div id="nav">
            <div id="navBar">
                <div class="one"></div>
                <div class="two"></div>
            </div>
            <ul>
                <li><a href="http://www.cnblogs.com/jianyeLee/">我的博客</a></li>
                <li><a href="javascript:myalert(‘我的微信dyznzyl‘)">我的微信</a></li>
                <li><a href="javascript:myalert(‘我的QQ2319048747‘)">我的QQ</a></li>
                <li><a href="javascript:myalert(‘我的邮箱lijianlin0204@163‘)">我的邮箱</a></li>
                <li><a href="javascript:myalert(‘我的邮箱lijianlin0204@163‘)">联系作者</a></li>
            </ul>
     </div>

 

第二步:现在来写css:首先在#header{}中再增加这几行代码,主要是设置背景颜色的样式,不加也无所谓:

    background: -webkit-linear-gradient(top, #9c6 0%, #2c2d33 100%);
    background: -moz-linear-gradient(top, #9c6 0%, #2c2d33 100%);
    background: -o-linear-gradient(top, #9c6 0%, #2c2d33 100%);
    background: -ms-linear-gradient(top, #9c6 0%, #2c2d33 100%);
    background: linear-gradient(top, #9c6 0%, #2c2d33 100%); 
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;

 

然后设置添加在HTML中一级导航的css样式:

#nav{width:960px;height:40px;line-height: 35px;position: relative;text-align:left;margin-left:320px; }
#navBar{position: absolute;top: 37px;}
.one{height: 2px;background: #fff;overflow:hidden}
.two{height: 1px;background: #aaa;overflow:hidden}
#header ul li{float:left;list-style: none}
#header ul li a{padding: 12px 15px;text-align: center;color: #fff;font-size: 14px; font-weight: bold;font-family: ‘宋体‘; text-decoration: none}

第三步:js编写

这样就差不多好了,可是这样没有一级菜单的的感觉啊!干巴巴的,不就是UL LI做成的普通链接样的么,别急我们通过js来控制,编写ethanNavMenu.js文件

同时引入到HTML页面中去,我们用jQuery的方式编写,我们还有引入jquery.js(可以到jQuery官网下载):<script type="text/javascript" src="../js/jquery.js"></script>

和<script type="text/javascript" src="ethanNavMenu.js"></script>

看js代码:

/*
**@EthanCoco原创导航菜单js
**@autor:EthanCoco
**@date:2015-08-18
**@email:lijianlin0204@163.com
*/
;$(function(){//别忘了最好在前面加个分号
    /**********************开始一级菜单****************************/
    //use strict添加严格模式
    ‘use strict‘;
    
    var tagNav = document.getElementById(‘nav‘);
    var tagBar = document.getElementById(‘navBar‘);
    
    //getElementsByTagName 返回的是一个数组, 【0】 表示取返回数组里面的第一个元素
    var tagLi =tagNav.getElementsByTagName(‘ul‘)[0].getElementsByTagName(‘li‘);
    var speed= 0;
    var timer, i , n, changeWidth;
    
    //offsetWidth = width + padding + border,
    //tagLi在上面是返回一个数组,tagLi[0]就是去第一个元素,并设置他的宽度
    //tagBar.style.width相当于:(document.getElementById(‘navBar‘).style.width;)获得整数值
    tagBar.style.width = tagLi[0].offsetWidth + ‘px‘;
    
    function sports(n, m) {
        timer = setInterval(function () {
            speed = (n - tagBar.offsetLeft) / 10;
            
            
            //Math.ceil()执行向上舍入,即它总是将数值向上舍入为最接近的整数;
            //Math.floor()执行向下舍入,即它总是将数值向下舍入为最接近的整数;
            //Math.round()执行标准舍入,即它总是将数值四舍五入为最接近的整数(这也是我们在数学课上学到的舍入规则)。
            speed = speed > 0 ? Math.ceil(speed) : Math.floor(speed);
            if (tagBar.offsetLeft === n) {
                clearInterval(timer);
            } else {
                //offsetLeft:获取对象相对于版面或由 offsetParent 属性指定的父坐标的计算左侧位置
                tagBar.style.left = tagBar.offsetLeft + speed + ‘px‘;
                
            }

            changeWidth = m - tagBar.offsetWidth;
            changeWidth = changeWidth > 0 ? Math.ceil(speed) : Math.floor(speed);
            tagBar.style.width = m + changeWidth  + ‘px‘;
            
        }, 20);
    }

    for (i = 0; i < tagLi.length; i += 1) {
        tagLi[i].onmouseover = function () {
            clearInterval(timer);
            sports(this.offsetLeft, this.offsetWidth);
        };
        tagLi[i].onmouseout = function () {
            clearInterval(timer);
            sports(0, tagLi[0].offsetWidth);
        };
    }    
    /**********************结束一级菜单****************************/
});

 

好了,然后我们来看看网页页面又是怎么样的呢?

看到多了个下标跟随鼠标的移动而移动,哎哟,这样看起来就像导航菜单了。

好了一级菜单就到此结束了。下面来看看手风琴式菜单  (引用jQueryUI和jQueryUICSS辅助)

(二)、手风琴式菜单  (引用jQueryUI和jQueryUICSS辅助)

第一步:在HTML中的id="content"的div中添加如下代码:

          <div id="accordion">
                    <h1>jQuery插件</h1>
                        <div class="plugin">
                            <button  onclick="javascript:turnUrl(‘4731439.html‘)">图片渐入渐出</button>
                            <button  onclick="javascript:turnUrl(‘4727434.html‘)">jQuery插件(一)</button>
                            <button onclick="javascript:turnUrl(‘4728564.html‘)">jQuery插件(二)</button>
                            <button onclick="javascript:turnUrl(‘4733514.html‘)">提示弹出框</button>
                        </div>
                    <h1>DIV+CSS</h1>
                        <div class="plugin">
                            <button onclick="javascript:turnUrl(‘4712396.html‘)">细节详解</button>
                            <button onclick="javascript:turnUrl(‘4709583.html‘)">常用语句</button>
                        </div>
                    <h1>博客邮箱</h1>
                        <div class="plugin">
                            <button onclick="javascript:turnUrl()">博客</button>
                            <button onclick="javascript:myalert(‘我的邮箱lijianlin0204@163.com,如有什么问题,发邮件给我!‘)">邮箱</button>
                        </div>
                </div>

 

第二步:我们需要引入jQueryUI和jQueryUICSS来辅助,这是里面自带的一种,把它放在HTML中:

<link rel="stylesheet" type="text/css" href="../css/jquery-ui.css"> 

<script type="text/javascript" src="../js/jquery.ui.js"></script>

在css中#content下添加如下样式:

/* <!-- 开始 手风琴式菜单css  引用jQueryUI和jQueryUICSS辅助 --> */
#accordion{width:300px;}
#accordion .plugin{background :LightCyan; color : DarkMagenta; height:140px;}
#accordion .plugin button{width:150px;}
/* <!-- 开始 手风琴式菜单css  引用jQueryUI和jQueryUICSS辅助 --> */

 

第三步:编写js,在结束一级菜单后面添加即可:

    /**********************开始手风琴式菜单****************************/
    $(‘#accordion‘).accordion({//accordion这个函数,就是jQueryUI提供的,跟validate,cookie,datepicker等一样的,只要引用就可以,这样$(‘#id‘).accordion();
        collapsible : false,
        icons : {    //改变下来的样式头标
            "header" : "ui-icon-plus",
            "activeHeader" : "ui-icon-minus",
        },
        activate : function(event,ui){
            $(‘#accordion‘).css(‘background‘,‘yellow‘);
        },
    }).css(‘float‘,‘right‘);
    $(‘#accordion .plugin button‘).button(); //通过jQueryUICSS设置button按钮的样式
    /**********************结束手风琴式菜单****************************/

 

在页面看看图的样式:

(三)、左或右悬浮式菜单

第一步:在继手风琴下面加入此代码,也同样是在id="content"下的div模块中,以左侧为例:

<!-- 开始 左侧悬浮菜单 -->
        <div id="side_left_menu">
          <ul class="side_list">
            <li>
              <div class="side_text">
                <h2><a href="javascript:turnUrl()" >我的博客</a></h2>
              </div>
            </li>
            <li>
              <div class="side_text">
                <h2><a href="javascript:myalert(‘有什么问题,邮箱给我lijianlin0204@163.com‘)" >我的邮箱</a></h2>
              </div>
            </li>
            <li>
              <div class="side_text">
                <h2><a href="javascript:myalert(‘我的微信dyznzyl‘)" >我的微信</a></h2>
              </div>
            </li>
            <li>
              <div class="side_text">
                <h2><a href="javascript:myalert(‘我的QQ2319048747‘)" >我的QQ</a></h2>
              </div>
            </li>
            <li>
              <div class="side_text">
                <h2><a href="javascript:myalert(‘我的微信dyznzyl‘)" >微信优先</a></h2>
              </div>
            </li>
          </ul>
        </div>
        <!-- 结束 左侧悬浮菜单 -->

 

第二步:加入css样式

/* <!-- 开始 左侧悬浮菜单 --> */
 #side_left_menu{width:250px; height:600px;
    position:absolute;
    z-index: 10;
    margin-left:305px;
    top:60px;
 }
 #side_left_menu .side_list{width:100%;height:auto; }
 #side_left_menu .side_list li{
     float:left;
     width:200px; 
     margin:0 auto;
     height:40px;
     margin-bottom:10px;
     box-shadow:2px 2px 4px rgba(0, 0, 0, 0.2);
     -webkit-transition:0.3s all ease;

     overflow:hidden;
     position:relative;
     border-right:5px solid orange;
     list-style-type : none;
    }
#side_left_menu .side_list li:hover{

    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
    box-shadow:2px 2px 4px rgba(0, 0, 0, 0.4);
    border-right:5px solid #fff;
}
#side_left_menu .side_text h2,#side_left_menu .side_text a{
    font-family:"Microsoft YaHei";
    color:GhostWhite;
    text-shadow:1px 2px 4px #999;
    font-size:20px;

    -ms-transition:0.3s all ease;
    -o-transition:0.3s all ease;
    line-height: 45px; 
    padding: 0px;
    margin: 0px; 
    text-align: left; 
    float: left;
    text-decoration:none;
}
 #side_left_menu .side_text h3{
     font-family:Verdana;
     font-size:14px;color:#666;
     font-weight:normal;-webkit-transition:0.3s all ease;
     -moz-transition:0.3s all ease;-ms-transition:0.3s all ease;
     -o-transition:0.3s all ease;
}
#side_left_menu .side_list li:hover h2, #side_left_menu .side_list li:hover  a{
    color:LightPink;
    font-size:28px;
    text-shadow:1px 2px 4px #333;

     -webkit-animation-name:shake;-moz-animation-name:shake;
}
 #side_left_menu .side_text{
     width:180px;height:auto;
     float:right;height:50px;-webkit-animation:.5s .2s ease both;
     -moz-animation:1s .2s ease both;
}
/* <!-- 结束 左侧悬浮菜单 --> */

在HTML的id=footer中的div中添加如下代码:

    <ul class="menu">
          <li><a href="javascript:turnUrl()">博客首页</a></li>
          <li><a href="javascript:myalert(‘我的微信dyznzyl‘)">Jquery插件</a>
                <ul>

                </ul>
            </li>
            <li><a href="javascript:myalert(‘我的QQ2319048747‘)">我的联系</a>
                <ul>
                  <li><a href="javascript:myalert(‘我的邮箱lijianlin0204@163.com‘)" class="documents">我的邮箱</a></li>

                </ul>
            </li>
          <li><a href="javascript:myalert(‘我的微信dyznzyl‘)">微信优先</a></li>
        </ul>

 

第二步:编写css:

#footer .menu{margin-left : 350px;height: 40px;width: 505px;background: #DDA0DD;
    background: -webkit-linear-gradient(top, #DDA0DD 0%, #2c2d33 100%);
    background: -moz-linear-gradient(top, #DDA0DD 0%, #2c2d33 100%);
    background: -o-linear-gradient(top, #DDA0DD 0%, #2c2d33 100%);
    background: -ms-linear-gradient(top, #DDA0DD 0%, #2c2d33 100%);
    background: linear-gradient(top, #DDA0DD 0%, #2c2d33 100%); 
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
}
#footer .menu li{position: relative;list-style: none;float: left;display: block;height: 40px;}
#footer .menu li a{
    display: block;
    padding: 0 14px;
    margin: 6px 0;
    line-height: 28px;
    text-decoration: none;
    border-left: 1px solid #393942;
    border-right: 1px solid #4f5058;
    font-family: Helvetica, Arial, sans-serif;
    font-weight: bold;
    font-size: 13px;
    color: #f3f3f3;
    text-shadow: 1px 1px 1px rgba(23,33,19,45);
    -webkit-transition: color .3s ease-in-out;
    -moz-transition: color .3s ease-in-out;
    -o-transition: color .3s ease-in-out;
    -ms-transition: color .3s ease-in-out;
    transition: color .3s ease-in-out;
}
#footer .menu li:first-child a {
    border-left: none;

(五)、树状菜单

第一步、在HTML中的div id="sidebar"下面添加如下代码,并为div id="sidebar"  添加一个class="menuTree":

<ul>
                <li class="par_tree"><a href="javascript:void(0)">我的联系</a>
                    <ul>
                        <li class="par_tree"><a href="#">我的微信</a>
                            <ul><li class="son_tree" ><a href="javascript:myalert(‘加个微信做个朋友!‘)">dyznzyl</a></li></ul>
                        </li>
                        <li class="par_tree"><a href="#">我的邮箱</a>
                            <ul><li class="son_tree"><a href="javascript:myalert(‘有关问题请发我邮箱!‘)">lijianlin0204@163.com</a></li></ul>
                        </li>
                        <li class="par_tree"><a href="#">我的QQ</a>
                            <ul><li class="son_tree"><a href="javascript:myalert(‘加QQ不如加微信吧!‘)">2319048747</a></li></ul>
                        </li>
                    </ul>
                </li>
                <li class="par_tree"><a href="javascript:void(0)">我的博客</a>
                    <ul>
                        <li class="par_tree"><a href="javascript:void(0)">HTML学习</a>
                        <ul>
                            <li class="par_tree"><a class="par_tree" href="javascript:void(0)">jQuery插件</a>
                                <ul>
                                    <li class="son_tree"><a href="javascript:turnUrl(‘4727434.html‘)">jQuery插件(一)</a></li>
                                    <li class="son_tree"><a href="javascript:turnUrl(‘4728564.html‘)">jQuery插件(二)</a></li>
                                    <li class="son_tree"><a href="javascript:turnUrl(‘4731439.html‘)">图片渐入渐出</a></li>
                                    <li class="son_tree"><a href="javascript:turnUrl(‘4733514.html‘)">提示弹出框</a></li>
                                </ul>
                            </li>
                            <li class="par_tree"><a href="javascript:void(0)">DIV+CSS</a>
                                <ul>
                                    <li class="son_tree"><a href="javascript:turnUrl(‘4712396.html‘)">细节详解</a></li>
                                    <li class="son_tree"><a href="javascript:turnUrl(‘4709583.html‘)">常用语句</a></li>
                                </ul>
                            </li>
                            <li class="son_tree"><a href="javascript:turnUrl()">博客地址</a></li>
                        </ul>
                        </li>
                    </ul>
                </li>
            </ul>

 

第二步、编写css,在#sidebar下面添加

.menuTree a{outline: none;}
.menuTree{width:300px;border:solid 1px black;}
.menuTree ul{font-size:100%;padding:5px;margin:0px;}
.menuTree ul li {list-style:none;padding-left:20px;line-height: 20px;white-space: nowrap;}
.menuTree ul li.par_tree a{color:#F4008F;text-decoration:none;padding:0px 2px;}
.menuTree ul li.par_tree a:hover{font-weight:blod;font-size:110%;}
.menuTree ul li.son_tree a{color:#FB7F2D;text-decoration:none;padding:0px 2px;}
.menuTree ul li.son_tree a:hover{font-weight:blod;font-size:110%;}
.menuTree ul li.par_tree{background: url(images/collapsed_image.gif) left top no-repeat;}
.menuTree ul li.expanded{background: url(images/expended_image.gif) left top no-repeat;}

 

第三步,我们单独用一个tree.js文件来写他的js,

引入<script type="text/javascript" src="tree.js"></script>到HTML。

if (jQuery) (function($) {

    $.extend($.fn, {
        menuTree: function(o, callback) {
            // Default parameters
            if (!o) var o = {};
            o.data = this.html();
            if (o.menuEvent == undefined) o.menuEvent = ‘click‘;
            if (o.expandSpeed == undefined) o.expandSpeed = 500;
            if (o.collapseSpeed == undefined) o.collapseSpeed = 500;
            if (o.expandEasing == undefined) o.expandEasing = null;
            if (o.collapseEasing == undefined) o.collapseEasing = null;
            if (o.multiOpenedSubMenu == undefined) o.multiOpenedSubMenu = false;
            if (o.parentMenuTriggerCallback == undefined) o.parentMenuTriggerCallback = false;
            if (o.expandedNode == undefined) o.expandedNode = null;

            $(this).each(function() {

                function bindTree(t) {

                    var liClickedSelector = callback != undefined ? ‘LI > A‘ : ‘LI.par_tree > A‘;
                    
                    $(t).find(liClickedSelector).bind(o.menuEvent, function() {
                        currentItem = $(this);
                        if ($(this).parent().hasClass(‘par_tree‘)) {
                            if ($(this).parent().hasClass(‘expanded‘)) {
                                // Collapse
                                $(this).parent().find(‘UL‘).slideUp({ duration: o.collapseSpeed, easing: o.collapseEasing });
                                $(this).parent().removeClass(‘expanded‘).addClass(‘collapsed‘);

                            } else {
                                // Expand
                                if (!o.multiOpenedSubMenu) {
                                    $(this).parent().parent().find(‘UL‘).slideUp({ duration: o.collapseSpeed, easing: o.collapseEasing });
                                    $(this).parent().parent().find(‘LI.par_tree‘).removeClass(‘expanded‘).addClass(‘collapsed‘);
                                }
                                $($(this).parent().find("UL")[0]).slideDown({ duration: o.expandSpeed, easing: o.expandEasing });
                                $(this).parent().removeClass(‘collapsed‘).addClass(‘expanded‘);
                                $(this).parent().find(‘LI.par_tree‘).removeClass(‘expanded‘).addClass(‘collapsed‘);

                                if (o.parentMenuTriggerCallback)
                                    callback($(this).attr(‘rel‘));
                            }

                        } else {
                            callback($(this).attr(‘rel‘));
                        }
                        return false;
                    });

                    // Prevent A from triggering the # on non-click events
                    if (o.menuEvent.toLowerCase != ‘click‘) $(t).find(liClickedSelector).bind(‘click‘, function() { return false; });
                }

                // initialization
                $($(this)).find(":first").show();
                bindTree($(this));

                // Expend default node
                if (o.expandedNode) {

                    var elementToExpend = $($(this)).find("a[rel=" + o.expandedNode + "]").parent().parent();

                    // Collect all UL items that need to be extended
                    var ulMenuElements = new Array();
                    var i = 0;
                    while (elementToExpend && elementToExpend.find(‘DIV‘).length == 0) {

                        if (elementToExpend[0].tagName == "UL") {
                            ulMenuElements[i] = elementToExpend;
                            i++;
                        }
                        elementToExpend = elementToExpend.parent();
                    }
                    ulMenuElements = ulMenuElements.reverse()

                    // Extend all collected item (recursive)
                    var i = 0;
                    var openMenu = function() {

                        i++; // skip first ul(root)
                        if (i >= ulMenuElements.length) return;

                        ulMenuElements[i].removeClass(‘collapsed‘).addClass(‘expanded‘);
                        ulMenuElements[i].slideDown({ duration: o.expandSpeed, easing: o.expandEasing, complete: openMenu });

                    }
                    openMenu(ulMenuElements);
                }
            });
        }
    });

})(jQuery);

 

第四步、在HTML中调用它:

  <script type="text/javascript">
        $(function() {
            $(‘#sidebar‘).menuTree();
            });
    </script>
