jQuery添加CSS样式 [英] jQuery add css style

问题描述

我有这个文本字符串，我想用新的文本字符串替换它，但是每次我这样做时，它的CSS都消失了.然后，我制作了一个脚本，将css添加回去，但是它似乎不起作用.有什么帮助吗?

I have this text string and I would like to replace it with new text string but everytime I do it the css of it was gone. And then I make a script to add the css back but it doesn't seem to work. Any help please?

jQuery('div:contains("text")').replaceWith('newText').css({font-weight:"bolder"});

谢谢

推荐答案

使用.text()代替:

jQuery('div:contains(text)').text('newText').css({"font-weight":"bolder"});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>text</div>

.replaceWith()方法用代码中的textNode替换了元素，并且font-weight css属性应该必须用引号引起来，或者使用camelCase命名约定fontWeight.

.replaceWith() method replaces the element with the textNode in your code and font-weight css property should have to be wrapped in either quotes or use camelCase naming convention fontWeight.
