jquery.tmpl 用法（附上详细案例）

js的模板引擎就和服务端的差不多，都是更好更快的拼接html用于显示，我参考了文章：http://www.cnblogs.com/zhuzhiyuan/p/3510175.html

tmpl常用标签

${}, {{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（使用{{=}}的时候=和变量之间一定要有空格，否则无效，即为：{{= 变量}}）

<div id="div_demo">
</div>
<script id="demo" type="text/x-jquery-tmpl">
    <div >
    　　<span>${ID}</span>
    　　<span style="margin-left:10px;">{{= ID}}</span>
    </div>
</script>
<script type="text/javascript">
　　var users = [{ ID: \'1111\'}];
　　$("#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)

<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>

该标签{{each}} {{/each}}需要两两配合，其实就是each迭代器的用法{{each(i,data) datas}} i是序号，data是单个数据，datas是数据集合，两这中间要有个空格

{{if }} {{else}}提供了分支逻辑相当于else if，参照js语法即可

<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>

4.
{{html}} 输出变量html,但是没有html编码，适合输出html代码

<div id="div_html"></div>
<script id="html" type="text/x-jquery-tmpl"> 
    <div style="margin-bottom:10px;">
    　　<div>${html}</div>
    　　<div>{{html html}}</div>
    </div>
</script> 
<script type="text/javascript">
　　var user = { html: \'<button>html</button>\' };
  　$("#html").tmpl(user).appendTo(\'#div_html\');
</script>

使用此字段注意{{html 变量}}中间也是一个空格

{{tmpl}} 嵌套模版

<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(Arr) \'#tmpl2\'}}</span>
    </div>     
</script>
<script id="tmpl2" type="type/x-jquery-tmpl">
    {{each(i,item) List}} 
        ${item.Name}
    {{/each}}   
</script>
<script type="text/javascript">
　　var users = { ID: \'think8848\', Arr: [ID:\'1111\',List: [{Name:\'Joseph\'},{ Name:\'Chan\'}]] };
   $("#tmpl1").tmpl(users).appendTo(\'#tmpl\');
</script>

同理{{tmpl(数据源) \'模板选择器\'}}

{{wrap}},包装器

<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>

7.
$data $item ：$item代表当前的模板；$data代表当前的数据。

<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>

8.
$.tmplItem()方法，使用这个方法，可以获取从render出来的元素上重新获取$item，即从渲染的html中拿出数据

<script type="text/javascript">
　　$(\'#demo\').delegate(\'div\', \'click\', function () {
                var item = $.tmplItem(this);
                alert(item.data.Name);
            });
</script>

$.template函数

    <script type="text/x-jquery-tmpl" id="tmpl01">
        <h1>{{= name}}</h1>
        <h1>${id}</h1>
        <h1>${$item.getName(" ")}</h1>
        <h1>${$data.id}</h1>
    </script>    
<script type="text/javascript">
        $(function () {
            var data = { id: \'2\', name: \'2222\' };
            //template函数可以定义模板
            $.template("movieTemplate", $(\'#tmpl01\'));
            $.tmpl(\'movieTemplate\', data).appendTo($(\'#test02\'));
        })
    </script>
    <div id="test02"></div>
