关于handler返回的数据处理

1、通过append方法输出数据到页面
/***************************根据企业ID获取企业信息*********************/

OBJindexPage.GetNewQiYeInfo = function () {
    $.getJSON("/Qiye/handler/QiyeBookInfo.ashx?callback=?", { QiYeID: ConfigQiYeInfoId.Get() ,action:"GetNewQiYeInfo"}, function (data) {     
        if (data == "0") {
            window.location.herf = "/Qiye/index.htm";
            return;
       }
       else {
            var QiyeInfo = "";
            QiyeInfo += " <img src=\"" + data[0].Logo + "\"  class=\"top_left_logo\"/>";
            QiyeInfo += "        <div id=\"top_left_div\">";
            QiyeInfo += "           <div class=\"top_left_title\">" + data[0].Name + "</div>";
            QiyeInfo += "           <div class=\"top_left_opentime\">借阅开放时间：" + data[0].Etime + "</div>";
            QiyeInfo += "           <div class=\"top_left_tel\">联系电话：" + data[0].Tel + "</div>";
            QiyeInfo += "           <div class=\"top_leftImg\"><a href=\"" + data[0].HomePage + "\"> <img src=\"Images/guanwang.png\" /></a> </div>";
            QiyeInfo += "        </div>";
             
            $("#top_left").append(QiyeInfo);
        }
    });
};

2、通过jquery.tmpl.js插件接收数据
htm 写法
<div id="bookdiv" class="bookdiv">

</div>
<script id="bookTmpl" type="text/html" class="bookTmpl">   //书写类型为 "text/html"的script 来做数据模板
<dl>
<dt><a target="_blank" href="/Book/Book_Info.aspx?id=${BookId}&bookCount=2"><img src="${BookImg}"/></a></dt>  //数据属性名用${}
<dd><a target="_blank" href="/Book/Book_Info.aspx?id=${BookId}&bookCount=2">${BookName.length > 8 ? BookName.substring(0,8) + "…" : BookName}</a></dd> //限制字符串长度
</dl>
</script>

js写法

$.getJSON(‘/Qiye/handler/QiyeBookInfo.ashx?callback=?‘, parameter, function(data) {
if (data=="0") {
$("#bookdiv").empty(); 
var noBookTips = " <span id=\"NoBookTips\">此馆暂无图书</span>";
$("#bookdiv").append(noBookTips);
} else {
$("#bookdiv").empty();
$("#bookTmpl").render(data).appendTo("#bookdiv");    //把数据添加到模板，然后再插入到父节点
}
});

3、分页事件的运用  

运用PagesWidget.js插件

/***************************企业图书分页数据************************/

OBJindexPage.GetQiYeList = function() {   
$("#ListInfoPages").empty();   //清空页码的div
var pageSize = 12;                //显示数据的数量
var parameter = OBJindexPage.GetSql();   //查找的条件
parameter.QiYeID = ConfigQiYeInfoId.Get();    //参数~
var iCount = 0;                                   
function GetCount() {
parameter.action = "GetQiYeBookCount";
$.ajaxSetup({ cache: true });
$.ajaxSetup({ async: false });
$.getJSON(‘/Qiye/handler/QiyeBookInfo.ashx?&callback=?‘, parameter, function(data) {
iCount = data;

});
return iCount;                 //返回数据全部的数量，根据这个数量和每页显示的数量来分页
}

function GetBookToQiYeList(pageIndex) {
parameter.PageIndex = pageIndex;        //页码
parameter.PageSize = pageSize;
parameter.action = "GetQiYeBookList";
$.getJSON(‘/Qiye/handler/QiyeBookInfo.ashx?callback=?‘, parameter, function(data) {
if (data=="0") {
$("#bookdiv").empty();
var noBookTips = " <span id=\"NoBookTips\">此馆暂无图书</span>";
$("#bookdiv").append(noBookTips);
} else {
$("#bookdiv").empty();
$("#bookTmpl").render(data).appendTo("#bookdiv");
}
});
}

var iBookToCoffeeCount = GetCount();
var buttonTextArray = new Array("first", "last", "&lt;", "&gt;");
var pagesParam = {                          //PagesWidget.js插件所需要的参数，就不一一细写
ButtonText: buttonTextArray,        
PanelId: ‘ListInfoPages‘,
Count: iBookToCoffeeCount,
PageSize: pageSize,
SearchText: false,       
FirstLastPages: false,   
Mousemove: true,
AjaxFn: GetBookToQiYeList
};
var oPages = CreatePagesWidget(pagesParam);
GetBookToQiYeList(1);
};
