最近用ajax获取数据，上级要求要自己写一个js模板，以往看到的js模板，大都数都是在js里面拼接的，现在换一种比较简单的写法，
通过ajax获取数据源,js模板循环显示数据
1 function GetBalance() { 2 var star = $("#starsj").val(); 3 var end = $("#endsj").val(); 4 var data = { opt: "GetAllotment", In: star, Out: end }; 5 var layindex = 0; 6 $.ajax({ 7 type: "POST", 8 url: "Source/GetData.aspx", 9 data: data, 10 beforeSend: function () { 11 }, 12 success: function (r) { 13 //r值是一个obj类型，里面包含了几个数组 14 if (r.Status == 0) { 15 //使用laytpl方法获取写好的模板读出后，用r的数据去填充 16 var ret = laytpl($("#tpl-prieshow").html()).render(r); 17 $("#tplmo").html(ret); //将最新的模板数据，通过div（tplmo）显示出来 18 } 19 }, 20 dataFilter: function (data, type) { 21 if (data.length > 0 && data != "{}") { 22 return $.parseJSON(data); 23 } 24 layer.msg(‘未查到数据!‘); 25 return null; 26 }, 27 error: function (XMLHttpRequest, textStatus, errorThrown) { layer.msg(‘网络出现错误了!,请刷新重试或者联系管理员‘); }, 28 complete: function (XMLHttpRequest, textStatus) { 29 layer.close(layindex); 30 } 31 }) 32 }
现在我们根据返回的json数据。看是否是数组和字符串
js模板 数组
得到r的数据格式
在js模板里面。为了避免错误。尽量不写注释。
1 { 2 "Status": 0, 3 "Allotments": [{ 4 "Status": 402, 5 "Used": 0, 6 "Locked": 0, 7 "Balance": 0 8 }, { 9 "Status": 402, 10 "Used": 0, 11 "Locked": 0, 12 "Balance": 0 13 }]
1 <div> 2 3 <div id="div_adduser" class="easyui-dialog" title="余额显示" style="width: 450px; height: 450px; "> 4 <div style="padding:8px 8px;border-radius:3px 4px;border-bottom:1px solid rgb(204,204,204);"><span>开始日期：<input id="starsj" class="Wdate"onfocus="WdatePicker({minDate:‘%y-%M-{%d+1}‘})" 5 style="width: 85px; height: 20px;" /> </span> <span>截止日期：<input id="endsj" class="Wdate" onfocus="WdatePicker({minDate:‘%y-%M-{%d+1}‘})"style="width: 85px; height:20px; padding-left:8px;" /></span> 6 <a class="easyui-linkbutton" plain="true" onclick="GetBalance()">确定日期</a></div> 7 <div id="tplmo" style="margin-top:2px;"></div> 8 </div> 9 <%--金额显示--%> 10 <script id="tpl-prieshow" type="text/html"> 11 {{# var dt=d.Allotments}} 12 <div style="padding-left:6px;"> 13 {{#for(var i=0;i<dt.length;i++){ }} //循环读取r里面的Allotments(这是一个数组)数据 ；这里两个大括号是输出的意思 14 <table style="margin:5px 0px;width:98%;border:1px solid rgb(204,204,204);padding:5px;" id=hf}" > 15 <tr> 16 <td> <span style="width:80px;font-size:13px;padding:5px;">配额日期：<label>{{dt[i].EntitlementDate}}</label> </span></td> 17 </tr> 18 <tr> <td><span style="width:80px;font-size:13px;padding:5px;">配额结余：<label style="color:bule;">{{dt[i].Balance}}</label> </span><td> 19 <td><span style="width:80px;font-size:13px;padding:5px;">锁定配额：<label style="color:red;">{{dt[i].Locked}}</label> </span></td> 20 <td><span style="width:90px;font-size:13px;padding:5px;">已用配额：<label style="color:Gray;">{{dt[i].Used}}</label></span></td> 21 </tr> 22 </table> 23 {{#} }} //和循环开始标签要成对（一般不再这里加注释。避免引起错误） 24 </div> 25 </script> 26 </div>
js模板 字符串
得到r的字符串格式
1 { "Status": 0, "Locked": 1630, "Balance": 1000000 }
1 <script id="tpl-prieshow" type="text/html"> 2 {{# var dt=d}}//获取的字符串 3 <div style="padding-left:6px;"> 4 //循环读取r里面字符串 ；这里两个大括号是输出的意思 5 <table style="margin:5px 0px;width:98%;border:1px solid rgb(204,204,204);padding:5px;" id=hf}" > 6 <tr> 7 <td> <span style="width:80px;font-size:13px;padding:5px;">配额日期：<label>{{dt.EntitlementDate}}</label> </span></td> 8 </tr> 9 <tr> <td><span style="width:80px;font-size:13px;padding:5px;">配额结余：<label style="color:bule;">{{dt.Balance}}</label> </span><td> 10 <td><span style="width:80px;font-size:13px;padding:5px;">锁定配额：<label style="color:red;">{{dt.Locked}}</label> </span></td> 11 <td><span style="width:90px;font-size:13px;padding:5px;">已用配额：<label style="color:Gray;">{{dt.Used}}</label></span></td> 12 </tr> 13 </table> 14 15 </div> 16 </script>
这是模板需要的js引用文件
