我希望能够创建由一些异步查询获取的数据填充的 jQuery 模板，为此我需要引用我在模板中渲染的元素。我想出了一个使用生成的类名的解决方案，我在渲染模板后使用它来插入数据，但这是一个拼凑。有没有办法从模板代码中获取对渲染元素的引用？这是我想要运行的代码:
<script>
function renderData(prduct_id, element){
getProductData(product_id, function(data){
$(e).empty();
$("#product-info-tmpl").tmpl({"data":data}).appendTo($(element));
});
}
</script>
<script id="product-info-loading-tmpl" type="text/x-jquery-tmpl">
loading
//Here is where I'd need a reference to the rendered element
${renderData(product_id, this_element_when_rendered)}
</script>
最佳答案
这有帮助吗，所以在你的情况下，有 $item 的东西，也许 $item.parent 或其他东西......
从 http://api.jquery.com/template-tag-equal/ 的某处复制
The $item and $data Template Variables The following variables are exposed to expression evaluation within templates:
$: The jQuery object. $item: The current template item - which allows access to $item.data, $item.parent, etc. as well as any user-defined values or methods passed in with the options map. $data: The current data item (equivalent to $item.data). Note: A template tag with content such as {{each}}...{{/each}} may expose additional variables to template evaluation within the content. In the case of {{each}}, for example, the additional template variables $value and $index are provided within the content of the {{each}} tag.
