jQuery.tmpl

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>
