【问题描述】:
这个想法是我想删除一个元素的内容,不包括用作 Handlebarjs 模板的脚本元素。
下面的示例完全有效,但我想知道是否有比我现在更好的方法?像我在示例中所做的那样使用 .remove() 或 .empty() 不会删除 TEXT 节点。即使更改 children() => find() 也不起作用。
示例:http://jsfiddle.net/076w8zdm/
// HTML
<div id="content">
<!--This Handlebars template should remain-->
<script type="text/x-handlebars-template">
<p>{{title}}, {{first_name}}, {{last_name}}</p>
</script>
This text node should be deleted.
<p>This element should be removed too.</p>
</div>
<!--Handlebars template example-->
// JS
// IIFE
; (function ($, undefined) {
console.log('Started');
// Cache the jQuery object
var $content = $('#content');
// Remove the contents of the div#content, but retain the Handlebars template
// $content.empty(); // <<<< Bad, as it removes everything
// These don't work, as the TEXT node isn't removed
// $content.children('*:not(script)').empty()
// $content.children('*:not(script)').remove();
// This works!
$content.contents().filter(function () {
console.log(this.nodeName);
// Only filter those which don't have the handlebars type and SCRIPT node name
return this.nodeName !== 'SCRIPT' || this.type !== 'text/x-handlebars-template';
// Remove from the DOM
}).remove();
console.log('Finished');
})(jQuery);
