当<script>中的type等于text/html时，我们可以做很多事件！

 1   <script id="commentTemplate" type="text/html">
 2      <li>
 3         <div class="photo">
 4             <a href="#">
 5                 <img src="[UserImg]" /></a></div>
 6         <p>
 7             <a href="#">[UserName]：</a><span class="time">[CreateDate]</span></p>
 8         <div class="clear">
 9         </div>
10     </li>
11     </script>

 1 <div id="comment_ul_2">
 2     </div>
 3     <input type="button" id="addFun" value="click me" />
 4     <script type="text/javascript">
 5         var reg = new RegExp("\\[([^\\[\\]]*?)\\]", 'igm'); //i g m是指分别用于指定区分大小写的匹配、全局匹配和多行匹配。
 6         $("#addFun").click(function () {
 7             var html = document.getElementById("commentTemplate").innerHTML;
 8             var source = html.replace(reg, function (node, key) { return { 'UserImg': '1', 'UserName': 'zhang', 'CreateDate': '2011-1-1'}[key]; });
 9             $("#comment_ul_2").append(source);
10         });
11 
12         var zzl = "name:[name]";
13         zzl = zzl.replace(reg, function (node, key) { return { 'name': '占占'}[key]; });
14         alert(zzl);
15 
16     </script>
