How can I replace %2C with a <comma> in javascript?
提问by Ryan
#&q=car&category=Car%20Audio%2CAccessories&brand=
I borrowed a this function from a previous question asked on SO:
我从上一个关于 SO 的问题中借用了这个函数：
function insertParam(key, value)
{
key = escape(key); value = escape(value);
var kvp = document.location.hash.substr(1).split('&');
var i=kvp.length; var x; while(i--)
{
x = kvp[i].split('=');
if (x[0]==key)
{
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if(i<0) {kvp[kvp.length] = [key,value].join('=');}
//this will reload the page, it's likely better to store this until finished
document.location.hash = kvp.join('&');
}
I use it like this:
我像这样使用它：
insertParam("category",xy);
insertParam("brand",zy);
My problem is it is decoding comma's to %2C. I know I can handle the characters on the server side, but how can I make it look pretty with javascript? By pretty I mean replace %2c with a comma.
我的问题是它正在将逗号解码为 %2C。我知道我可以处理服务器端的字符，但是我怎样才能用 javascript 让它看起来漂亮呢？漂亮我的意思是用逗号替换 %2c 。

decodeURIComponent(foo)is the thing you are looking for.
decodeURIComponent(foo)是你正在寻找的东西。
Edit: Misread your question.
编辑：误读你的问题。
Use replace(/&/g, "%26").replace(/=/g, "%3D")instead of escapeon key and value to do this.
使用replace(/&/g, "%26").replace(/=/g, "%3D")代替escape键和值来执行此操作。
None of the 3 functions encodeURI, encodeURIComponentor encodework for this task, because they either encode commas or don't encode &=.
无的3个功能encodeURI，encodeURIComponent或encode工作完成这个任务，因为它们要么编码逗号或不编码&=。

I do not know why in the previous answer that was striked out, but the answer was correct.
我不知道为什么在以前的答案中被删除了，但答案是正确的。
alert(decodeURIComponent('%2C'));
So, you break your query strings into elements, splitting by & symbol. Than you split the results by = symbol and apply decodeURIComponent on both name and the value.
因此，您将查询字符串分解为元素，并按 & 符号拆分。比你用 = 符号分割结果并对名称和值应用 decodeURIComponent 。
ps: key = escape(key); value = escape(value);you should not use escape here (it is different for different browsers. and by 'different' I meant IE). Use encodeURIComponent.
ps：key = escape(key); value = escape(value);你不应该在这里使用转义（不同的浏览器是不同的。“不同”我的意思是IE）。使用 encodeURIComponent。
pps: because they either encode commas or don't encode &=???
pps：because they either encode commas or don't encode &=？？？
alert(encodeURIComponent('&=,'));
outputs %26%3D%2C
输出 %26%3D%2C

This worked for me for undoing encodeURIComponent()on URIs that contain commas:
这对我来说适用于撤消encodeURIComponent()包含逗号的 URI：
.replace(/%2C/g,",")
