jQuery从html字符串中删除html标签 [英] jquery Remove html tags from html string

问题描述

我需要将html字符串从页面加载到内存中，并使用jQuery删除具有特定类的div.

I need to load an html string into memory from the page and remove divs that have a certain class using jQuery.

我想做的事情在下面，但不起作用.

What I am trying to do is below but it doesn't work.

var reportHTML = $('#collapsereportsdata').html()
$(reportHTML).(".dontprintme").each().remove();

谢谢

推荐答案

要获取已删除标签的HTML，您可以 .clone() 元素，并在获取HTML之前删除不需要的元素，如下所示:

To get the HTML with the tags removed you can .clone() the element and remove the elements you don't want before getting it's HTML, like this:

var newHTML = $('#collapsereportsdata').clone().find(".dontprintme")
                                               .remove().end().html();

这将执行原始元素的 .clone() ，并执行 .remove() ，然后使用 .end() 跳回到克隆的元素，因为那是您想要通过 .html() 来获取html的元素.

This performs a .clone() of the original element, does a .find() to get the elements you want to .remove(), then uses .end() to jump back to the cloned element, since that's the one you'd want to get the html via .html() from.
