template.js前端模板引擎使用详解

<script id="tpl" type="text/html">
<ul>
  <%for(var i = 0; i < list.length; i++) {%>
  <li><%:=list[i].name%></li>

</ul>
</script>

var tpl = document.getElementById('tpl').innerHTML;
template(tpl, {list: [{name: "yan"},{name: "haijing"}]});

<ul>
  <li>yan</li>
  <li>haijing</li>
</ul>

<script id="tpl" type="text/html">
  <table>
