如何使用jQuery删除html字符串中的元素

Question

我有一个Html字符串,我想将其解析为HTML,然后删除任何pre标签和它的孩子.我试过这个:

HTMLString = "<p>a paragraph</p><p>second Paragraph</p><pre>&lt;script&gt;&nbsp;&nbsp;&nbsp;&nbsp;function (){&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;something();&nbsp;&nbsp;&nbsp;&nbsp;}&lt;/script&gt;</pre>";
var $jQueryObject = $($.parseHTML(HTMLString));
alert($jQueryObject.find('pre').length);

但这提示我0表示它找不到任何pre标签.谁能告诉我我的代码有什么问题？

这是我的小提琴

HTMLString = "<p>a paragraph</p><p>second Paragraph</p><pre>&lt;script&gt;&nbsp;&nbsp;&nbsp;&nbsp;function (){&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;something();&nbsp;&nbsp;&nbsp;&nbsp;}&lt;/script&gt;</pre>";
    var $jQueryObject = $($.parseHTML(HTMLString));
alert($jQueryObject.find('pre').length);
