jQuery.tmpl.js是一款动态请求数据，然后自动拼装HTML的组件。很多时候ajax请求基本上都是请求JSON，XML等数据然后前端拼装html，这个真是一件很蛋疼的事儿。
jquery.tmpl的几种常用标签分别有：
${}, {{each}}, {{if}}, {{else}}, {{html}}
不常用标签
{{=}},{{tmpl}} and {{wrap}}.
${}等同与{{=}}是输出变量 ${}里面还可以放表达式 （=和变量之间一定要有空格，否则无效）
示例：
<div id="div_demo">
</div>
<script id="demo" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;">
<span>${ID}</span>
<span style="margin-left:10px;">{{= Name}}</span>
<span style="margin-left:10px;">${Number(Num)+1}</span>
<span style="margin-left:10px;">${Status}</span>
</div>
</script>
<script type="text/javascript">
var users = [{ ID: ‘think8848‘, Name: ‘Joseph Chan‘, Num: ‘1‘, Status: 1 }, { ID: ‘aCloud‘, Name: ‘Mary Cheung‘, Num: ‘2‘}];
$("#demo").tmpl(users).appendTo(‘#div_demo‘);
</script>
{{each}} 提供循环逻辑，$value访问迭代变量 也可以自定义迭代变量(i,value)
示例：
<div id="div_each">
</div>
<script id="each" type="text/x-jquery-tmpl">
<h3>users</h3>
{{each(i,user) users}}
<div>${i+1}:{{= user.name}}</div>
{{if i==0}}
<h4>group</h4>
{{each(j,group) groups}}
<div>${group.name}</div>
{{/each}}
{{/if}}
{{/each}}
<h3>depart</h3>
{{each departs}}
<div>{{= $value.name}}</div>
{{/each}}
</script>
<script type="text/javascript">
var eachData = { users: [{ name: ‘jerry‘ }, { name: ‘john‘}], groups: [{ name: ‘mingdao‘ }, { name: ‘meihua‘ }, { name: ‘test‘}], departs: [{ name: ‘IT‘}] };
$("#each").tmpl(eachData).appendTo(‘#div_each‘);
</script>
{{if }} {{else}}提供了分支逻辑 {{else}} 相当于else if
示例：
<div id="div_ifelse"></div>
<script id="ifelse" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;"><span>${ID}</span><span style="margin-left:10px;">{{= Name}}</span>
{{if Status}}
<span>Status${Status}</span>
{{else App}}
<span>App${App}</span>
{{else}}
<span>None</span>
{{/if}}
</div>
</script>
<script type="text/javascript">
var users = [{ ID: ‘think8848‘, Name: ‘Joseph Chan‘, Status: 1, App: 0 }, { ID: ‘aCloud‘, Name: ‘Mary Cheung‘, App: 1 }, { ID: ‘bMingdao‘, Name: ‘Jerry Jin‘}];
$("#ifelse").tmpl(users).appendTo(‘#div_ifelse‘);
</script>
{{html}} 输出变量html,但是没有html编码，适合输出html代码
实例
<div id="div_html"></div>
<script id="html" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;">
<span>${ID}</span>
<span style="margin-left:10px;">{{= Name}}</span>
${html}
{{html html}}
</div>
</script>
<script type="text/javascript">
var user = { ID: ‘think8848‘, Name: ‘Joseph Chan‘, html: ‘<button>html</button>‘ };
$("#html").tmpl(user).appendTo(‘#div_html‘);
</script>
{{tmpl}} 嵌套模版
实例
<div id="tmpl"></div>
<script id="tmpl1" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;">
<span>${ID}</span>
<span style="margin-left:10px;">{{tmpl($data) ‘#tmpl2‘}}</span>
</div>
</script>
<script id="tmpl2" type="type/x-jquery-tmpl">
{{each Name}}${$value} {{/each}}
</script>
<script type="text/javascript">
var users = [{ ID: ‘think8848‘, Name: [‘Joseph‘, ‘Chan‘] }, { ID: ‘aCloud‘, Name: [‘Mary‘, ‘Cheung‘]}];
$("#tmpl1").tmpl(users).appendTo(‘#tmpl‘);
</script>
{{wrap}},包装器
实例
<div id="wrapDemo">
</div>
<script id="myTmpl" type="text/x-jquery-tmpl">
The following wraps and reorders some HTML content:
{{wrap "#tableWrapper"}}
<h3>One</h3>
<div>
First <b>content</b>
</div>
<h3>Two</h3>
<div>
And <em>more</em> <b>content</b>...
</div>
{{/wrap}}
</script>
<script id="tableWrapper" type="text/x-jquery-tmpl">
<table cellspacing="0" cellpadding="3" border="1"><tbody>
<tr>
{{each $item.html("h3", true)}}
<td>
${$value}
</td>
{{/each}}
</tr>
<tr>
{{each $item.html("div")}}
<td>
{{html $value}}
</td>
{{/each}}
</tr>
</tbody></table>
</script>
<script type="text/javascript">
$(function () {
$(‘#myTmpl‘).tmpl().appendTo(‘#wrapDemo‘);
});
</script>
$data $item $item代表当前的模板；$data代表当前的数据。
实例：
<div id="div_item_data"></div>
<script id="item_data" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;">
<span>${$data.ID}</span>
<span style="margin-left:10px;">${$item.getName(" ")}</span>
</div>
</script>
<script type="text/javascript">
var users = [{ ID: ‘think8848‘, Name: [‘Joseph‘, ‘Chan‘] }, { ID: ‘aCloud‘, Name: [‘Mary‘, ‘Cheung‘]}];
$("#item_data").tmpl(users,
{
getName: function (spr) {
return this.data.Name.join(spr);
}
}).appendTo(‘#div_item_data‘);
</script>
