如何在JavaScript中解码url编码的字符串 [英] How to decode url-encoded string in javascript

问题描述

我使用javascript/jquery填充包含变音符号的dom元素:

I use javascript / jquery to fill dom elements that contain umlauts:

var text1 = "Unser platonisches Internetreich droht in die H%E4nde einer bewaffneten Miliz zu fallen."

$("#quote1 span").html(unescape(text1));

如何摆脱网址编码，例如"H％E4nde"并改用Hände"?我尝试过

How can I get rid of the url encoding e.g. "H%E4nde" and use "Hände" instead? I tried

<meta charset="utf-8" />

<meta name="http-equiv" content="Content-type: text/html; charset=UTF-8"/>

<script type="text/javascript" src="js/index.js" charset="utf-8"></script>

但是它们似乎都不起作用...

But none of them seem to work...

感谢您的帮助.

推荐答案

不是UTF-8，即百分比编码也称为url编码.

That is not UTF-8, that is percent encoding also known as url encoding.

您可以使用 decodeURIComponent()将其转换回显示之前的状态

You can use decodeURIComponent() to convert it back before displaying it

$("#quote1 span").html(decodeURIComponent(text1));
