    }).when(TempoEvent.Types.RENDER_COMPLETE, function (event) {
        $(‘#tweets‘).removeClass(‘loading‘);
    }).render(data);


2.template.starting()手动调用开始事件
var template = Tempo.prepare(‘tweets‘).when(TempoEvent.Types.RENDER_STARTING, function (event) {
            $(‘#tweets‘).addClass(‘loading‘);
        }).when(TempoEvent.Types.RENDER_COMPLETE, function (event) {
            $(‘#tweets‘).removeClass(‘loading‘);
        });
template.starting();
$.getJSON(url, function(data) {
    template.render(data.results);
});

3. jQuery  live() 事件
$(‘ol li‘).live(‘click‘, function() {
    // Do something with the clicked element
    alert(this);
});

{% if javascript-expression %} ... {% else %} ... {% endif %}   //{% else %} 为可选块

Data-if-字段名="值"
       <li data-template  data-if-sex="母">{{Name}}</a></li>

Data-has="是否存在的字段"
       <li data-template  data-has="ifBianZhong">{{Name}}</a></li>

Data-src="{{字段名|append ‘.png‘}}"
       <img src="1.gif" data-src="{{Image| append ‘.png‘}}"  />
