给select下拉框赋值option，会多出一个空的option标签
```
<select name="" id="catalogContainer" class="select">
</select>

<script id="catalogSelect" type="text/html">
    {{each list as value i}}
    	<option value={{value.id}}>{{value.name}}<option>
    {{/each}}
</script>
```

```
//获取分类
$(function() {
    _ajax("GET", {}, _catalogAPI.list, _ajaxContentType.FORM, "JSON", sucCatalogMethod, errCatalogMethod);
})

//分类下拉框的数据
var data = {
    list : [

    ]
}

function sucCatalogMethod(response) {
    data.list = response.result;
    var html = template('catalogSelect', data);
    console.info(html);
    // var result = html.replace(/[\r\n]/g, "").replace(/[ ]/g,"");
    document.getElementById('catalogContainer').innerHTML = html;
}
```

输出结果
