jquery替换不起作用 [英] jquery replace is not working

问题描述

DEMO

您好我在尝试从JS中删除箭头。但似乎替换不起作用:-(

Hi Am trying to remove the arrows from JS. but seems like replace is not working :-(

<a class="pr-page-prev">« Previous</a>
<a class="pr-page-next">Next »</a>


$('.pr-page-prev').text().replace(/&laquo;/, '')
$('.pr-page-next').text().replace(/&raquo;/, '')

推荐答案

您正在替换文本而不是内容元素。

You are replacing the text but not the content of the element.

当你说 $（'。pr-page-prev'）。text（）时，它返回你正在调用replace的文本内容，它将返回被替换的文本，但它不会被设置回元素。所以即使你已经替换了文本，它也不会被应用到元素。

When you say $('.pr-page-prev').text(), it returns the text content on which you are calling replace which will return the replaced text but it is not set back to the element. So even if you have replaced the text it won't be applied to the element.

$('.pr-page-prev').text(function(i, text){return text.replace(/«/, '')})
$('.pr-page-next').text(function(i, text){return text.replace(/»/, '')})
