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: '1111'}]; $("#demo").tmpl(users).appendTo('#div_demo'); </script>
2.
{{each}} 提供循环逻辑,$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>${i+1}:{{= user.name}}</div> {{if i==0}} <h4>group</h4> {{each(j,group) groups}} <div>${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'}] }; $("#each").tmpl(eachData).appendTo('#div_each'); </script>
该标签{{each}} {{/each}}需要两两配合,其实就是each迭代器的用法{{each(i,data) datas}} i是序号,data是单个数据,datas是数据集合,两这中间要有个空格
3.
{{if }} {{else}}提供了分支逻辑相当于else if,参照js语法即可
<div id="div_ifelse"></div> <script id="ifelse" type="text/x-jquery-tmpl"> <div style="margin-bottom:10px;"><span>${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: 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>' }; $("#html").tmpl(user).appendTo('#div_html'); </script>
使用此字段注意{{html 变量}}中间也是一个空格
5.
{{tmpl}} 嵌套模版
<div id="tmpl"></div> <script id="tmpl1" type="text/x-jquery-tmpl"> <div style="margin-bottom:10px;"> <span>${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:'1111',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="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>
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: '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>
