jsrender在for循環中獲取上級數據

使用~root可以在模板中訪問到頂層數據，從頂層數據往下就可以訪問到所有數據了，如下：

<script id="item-list" type="text/x-jsrender">
    {{for items}}
        {{if ~root.type == "pic"}}
            <tr>
                <td>{{:id}}</td>
                <td><img src="{{:pic}}" /></td>
            </tr>
        {{else ~root.type == "name"}}
            <tr>
                <td>{{:id}}</td>
                <td>{{:name}}</td>
            </tr>
        {{/if}}
    {{/for}}
</script>
<script type="text/javascript">
    var picitems = [
        {id:1, pic:"/images/1.png" },
        {id:2, pic:"/images/2.png" },
        {id:3, pic:"/images/3.png" }
    ];
    var html = $("#item-list").render({ type: "pic", items: picitems });
    $("#allitems").append(html);

    var nameitems = [
        { id: 1, name: "/images/1.png" },
        { id: 2, name: "/images/2.png" },
        { id: 3, name: "/images/3.png" }
    ];
    var html = $("#item-list").render({ type: "name", items: nameitems });
    $("#allitems").append(html);

</script>

jsrender對語法要求非常嚴格，比如for，if前面不能有空格
