在网页中使用自定义右键菜单,实现上皆为使用javascript禁用浏览器默认的右键菜单,然后在网页中响应鼠标右键事件,弹出自定义的菜单。
类似右键菜单的组件网上很多。一般而言,改变浏览器的默认菜单应当慎用,这会使多数用户感到不习惯。但是在企业Web应用中,用户的使用环境更加可控,在这种应用中使用自定义右键菜单会更加适合。
以下列举几款比较成熟的jQuery右键菜单插件,我们将逐一介绍,请读者自行比较,并根据自己的需求选择。
1.VERY SIMPLE CONTEXT MENU-Intekhab A Rizvi
Project Page: http://intekhabrizvi.wordpress.com/2010/01/28/jquery-very-simple-contextmenu-plugin/
jQuery Very Simple ContextMenu Plugin
使用:
1.在插件主页下载所需文件。
2.在你的html文件中包含jquery库,vscontext.jquery.js,css/vscontext.css。
<script src="jquery.js" type="text/javascript"><!--mce:0--></script>
<script src="vscontext.jquery.js" type="text/javascript"><!--mce:1--></script>
3.在html中创建要响应右键菜单的元素。
<div id="item">右键点我</div>
4.创建菜单项目。
<li>的class有seprator的,会在该项下面有一条分割线。
<div >
<ul>
<li ><a id="menu_1" href="javascript:cut();">剪切</a></li>
<li ><a id="menu_2" href="javascript:copy();">复制</a></li>
<li ><a id="menu_3" href="javascript:paste();">粘贴</a></li>
<li ><a id="menu_4" href="javascript:edit();">编辑</a></li>
<li ><a id="menu_5" href="javascript:del();">删除</a></li>
</ul>
</div>
菜单项的图标要在css文件里设置相应<li>的背景。
.vs-context-menu li.cut a { background-image: url(icons/cut.png); }
.vs-context-menu li.copy a { background-image: url(icons/copy.png); }
.vs-context-menu li.paste a { background-image: url(icons/paste.png); }
.vs-context-menu li.edit a { background-image: url(icons/edit.png); }
.vs-context-menu li.delete a { background-image: url(icons/delete.png); }
5.初始化菜单,添加菜单事件。
<script type="text/javascript"><!--mce:2--></script>
2.CONTEXT MENU-Cory S.N. LaViska
Project Page: http://abeautifulsite.net/blog/2008/09/jquery-context-menu-plugin/
jQuery Context Menu Plugin
使用:见插件官方网站。
Methods:
disableContextMenu() | 禁用匹配元素上的右键菜单。 |
enableContextMenu() | 启用匹配元素上的右键菜单。 |
disableContextMenuItems(”#option1,#option2,…”) | 禁用匹配的菜单项,如果参数为null,禁用所有项。 |
enableContextMenuItems(”#option1,#option2,…”) | 期用匹配的菜单项,如果参数为null,禁用所有项。 |
destroyContextMenu() | 解除元素与右键菜单的绑定。 |
Callback:
action | 选中的菜单项所对应的动作。 |
el | 触发菜单的元素 |
pos.x | 菜单点击时,鼠标位置相对于触发元素的水平位移。 |
pos.y | 菜单点击时,鼠标位置相对于触发元素的垂直位移。 |
pos.docX | 菜单点击时,鼠标位置相对于页面的水平位移。 |
pos.docY | 菜单点击时,鼠标位置相对于页面的垂直位移。 |
3.JEEGOOCONTEXT-Erik van den Berg
Project Page: http://www.planitworks.nl/jeegoocontext/
JEEGOOCONTEXT
菜单可以通过以下两种方法初始化:
$(‘selector‘).jeegoocontext(‘menu_id‘);
$(‘selector‘).jeegoocontext(‘menu_id‘, ‘options‘);
“selector”为菜单组建要绑定的内容,可以是任何jQuery选择器。
“menu_id”为菜单ID(没有 “#”)。
“options”为对象,可以配置属性和回调函数。
所有菜单内容都可以从菜单解绑,只需调用:
$ (‘context‘).nojeegoocontext();
Options properties:
livequery | Boolean | undefined | Menu | 如为true, 菜单内容通过livequery生成并动态加载。 |
hoverClass | String | ‘hover’ | Menu | 这个CSS类在鼠标悬停在菜单项或其直接子项时被设置。 |
activeClass | String | ‘active’ | Global | 这个CSS类设置给当前活动的菜单 (右键点击会弹出菜单的区域)。 这个变量是全局的,在使用多个菜单时只需要设置一次。如果重复设置,其值为最后提供的。 |
menuClass | String | ‘jeegoocontext’ | Global | 所有的菜单都必须包含这个CSS类。这个变量是全局的,在使用多个菜单时只需要设置一次。如果重复设置,其值为最后提供的。 |
autoAddSubmenuArrows | Boolean | true | Menu | 如为true,则自动为有子项的菜单项添加指示箭头。 |
submenuClass | String | ‘submenu’ | Menu | 如果autoAddSubmenuArrows为true, 这个类设置给菜单项中包含小箭头的<span>元素。 |
separatorClass | String | ‘separator’ | Menu | 当某个菜单项含有此类,则在按键盘上下键切换菜单项时,该菜单项被跳过。 |
fadeIn | Number | 200 | Menu | 菜单和子级菜单淡入的时间,单位为毫秒。 |
delay | Number | 300 | Menu | 鼠标移出父菜单项时,其子菜单隐藏的延迟时间,单位为毫秒。 |
keyDelay | Number | 100 | Menu | 上下键切换菜单项的延迟时间,单位为毫秒。 |
widthOverflowOffset | Number | 0 | Menu | 可以在宽度溢出时使用。例如设置为20时,菜单和子菜单的右部总是离窗口右边界有20px的间距。 |
heightOverflowOffset | Number | 0 | Menu | 可以在高度溢出时使用。例如设置为20时,菜单和子菜单的底部总是离窗口下边界有20px的间距。 |
submenuLeftOffset | Number | 0 | Menu | 子菜单相对于父菜单的水平位移。如为-3,每个子菜单左部将有3px与父菜单重叠。 |
submenuTopOffset | Number | 0 | Menu | 子菜单相对于父菜单的垂直位移。如为-3,每个子菜单将比其父菜单项高出3px。当然,在高度溢出的情况下,此值被忽略。 |
operaEvent | String | ‘dblclick’ | Menu | 在Opera的9.5以前老版本中浏览器右键菜单时是禁止重写的,这个事件用来定义在Opera中如何打开菜单。 |
event | String | undefined | Menu | 此项被设置时,定义的事件将用来取代右键打开菜单。优先于operaEvent属性。例如,设置为’click’将使用左键打开菜单。 |
Options callbacks
可设置以下4个回调:
onShowonHoveronSelectonHide
每个回调接收两个参数:e 和 context,e为该事件的来源元素,context为菜单弹出所在的区域。利用这些回调函数,可以用return false的方法取消菜单事件的默认行为。
onShow | menu | Right-click on bound context. | 隐藏页面上所有菜单。在页面上删除所有处于active的菜单及菜单项的active类。为当前点击的内容添加active类。淡入菜单。 |
onHover | menu-item | Mouseover on menu-item. | 定位并淡入子级菜单。 |
onSelect | menu-item | Click on menu-item. | 删除当前处于active的菜单或菜单项的active类。隐藏菜单。 |
onHide | menu | Click on document. | 在页面上删除所有处于active的菜单及菜单项的active类。隐藏菜单。 |
4.JQUERY CONTEXT MENU SCRIPT-Dynamic Drive
Project Page: http://www.dynamicdrive.com/dynamicindex1/contextmenu.htm
jQuery Context Menu script
这也是一个简单的右键菜单,菜单内容同样用<ul>和<li>嵌套构造多级菜单。使用方法参看插件页面。
5.CONTEXT MENU-Chris Domigan
Project Page: http://www.trendskitchens.co.nz/jquery/contextmenu/
ContextMenu plugin
这也是一个名为Context Menu的插件。
使用:
参数:
menu_id
通过引用菜单的ID,你可以在多个元素上绑定相同的菜单。如:
$("table td").contextMenu("myMenu")
将会把ID为”myMenu”的菜单绑定到所有的表格单元格上。
settings
settings支持以下属性:
bindings | 包含”id”:function对的对象。提供的函数为点击时的动作。触发菜单的元素作为第一个参数传递给该句柄。 |
menuStyle | 包含styleName:value对的对象,定义菜单容器ul的样式。 |
itemStyle | 包含styleName:value对的对象,定义菜单项li的样式。 |
itemHoverStyle | 包含styleName:value对的对象,定义菜单项li的悬停样式。 |
shadow | 布尔值,默认为true。菜单是否显示阴影。 |
eventPosX | 允许你定义菜单弹出的位置,默认为pageX。IE6下需设置为clientX。 |
eventPosY | 允许你定义菜单弹出的位置,默认为pageX。IE6下需设置为clientY。 |
onContextMenu(event) | 在菜单显示前调用。如果返回false,将不显示菜单。 |
onShowMenu(event, menu) | 在菜单显示前调用。它将传递一个reference给菜单元素,并允许你在菜单显示之前手动修改输出,你可以在菜单显示给用户之前,显示或隐藏参数或其他任何东西。该函数必须返回menu |
另外的,你可以调用:
$.contextMenu.defaults(settings)
为所有菜单定义一个默认样式。

Project Page: http://code.google.com/p/xjplugin/source/browse/trunk/ControlsSample/Javascripts/Plugins/jquery.contextmenu.js
这是一个国人在另一个右键菜单脚本的基础上,修改bug并jQuery插件化得到的插件……小巧易用,功能还不错,菜单内容为json传入,而不是把ul li格式化。
ContextMenu
话不多说,直接上Demo完整代码。参数使用方法请看参看注释和示例。
