拓展用法
<script id="datatmp3" type="text/html">
{{if isAdmin}}
<h1>{{title}}</h1>
<ul>
{{each list as value i}}
<li>索引 {{i + 1}} ：{{value}}</li>
{{/each}}
</ul>
</script>
<script>
var data = {
title: '基本例子',
isAdmin: true,
list: ['文艺', '博客', '摄影', '电影', '民谣', '旅行', '吉他']
};
$(".page").html(template('datatmp3', data));
template.helper("totime", function (timestamp) {
var date = new Date(timestamp);
Y = date.getFullYear() + '-';
M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
