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}}.
1.
${}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: ''}];
$("#demo").tmpl(users).appendTo('#div_demo');
</script>
2.
{{each}} 提供循环逻辑,$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>${i+}:{{= user.name}}</div>
{{if i==}}
<h4>group</h4>
{{each(j,group) groups}}
<div>${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'}] };
$("#each").tmpl(eachData).appendTo('#div_each');
</script>
该标签{{each}} {{/each}}需要两两配合,其实就是each迭代器的用法{{each(i,data) datas}} i是序号,data是单个数据,datas是数据集合,两这中间要有个空格
3.
{{if }} {{else}}提供了分支逻辑相当于else if,参照js语法即可
<div id="div_ifelse"></div>
<script id="ifelse" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;"><span>${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: , App: }, { ID: 'aCloud', Name: 'Mary Cheung', App: }, { 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>' };
$("#html").tmpl(user).appendTo('#div_html');
</script>
使用此字段注意{{html 变量}}中间也是一个空格
5.
{{tmpl}} 嵌套模版
<div id="tmpl"></div>
<script id="tmpl1" type="text/x-jquery-tmpl">
<div style="margin-bottom:10px;">
<span>${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:'',List: [{Name:'Joseph'},{ Name:'Chan'}]] };
$("#tmpl1").tmpl(users).appendTo('#tmpl');
</script>
同理{{tmpl(数据源) '模板选择器'}}
6.
{{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="" cellpadding="" border=""><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>
9.
$.template函数
<script type="text/x-jquery-tmpl" id="tmpl01">
<h1>{{= name}}</h1>
<h1>${id}</h1>
<h1>${$item.getName(" ")}</h1>
<h1>${$data.id}</h1>
</script>
<script type="text/javascript">
$(function () {
var data = { id: '', name: '' };
//template函数可以定义模板
$.template("movieTemplate", $('#tmpl01'));
$.tmpl('movieTemplate', data).appendTo($('#test02'));
})
</script>
<div id="test02"></div>
