使用location.search定位参数的值 [英] Using location.search to locate a parameter's value

问题描述

我正在开发一个工具，它接受网址中的值参数，然后用它们做一些事情。

I’m working on a tool which takes the value parameters in the URL and does a few things with them.

我的问题是，我似乎无法忍受使用document.location来显示我所追求的特定值，例如：

My issue is, I can’t seem to use document.location to show the specific value that I’m after, for example:

www.examplesite.com?yourname=gilgilad

我想使用document.location.search并将其放在var中，我需要将var的值设为gilgilad。

I want to use document.location.search and put it in a var, I need that var's value to be "gilgilad".

这是否可以使用location.search？

Is this even possible using location.search?

推荐答案

location.search 将在包含它的问号后返回所有问题。所以有通用的js来获取第一个参数的值（即使url有更多的参数）：

location.search will return all after question mark including it. So there is universal js to get value of the first parameter (even if url has more parameters):

var desire = location.search.slice(1).split("&")[0].split("=")[1]

示例：让我们拿网址 http://example.com?name=jon&country=us

1. location.search 将等于？name = jon& country = us


2. '。slice（1）'跳过'？'，返回字符串的其余部分。
   3 .split（&）[0] 将其拆分为两个字符串（？name = jon 和 country = us ）并取第一个


3. .split（=）[1 ] 将 name = jon 拆分为 name 和 jon 并采取第二个。完成！

1. location.search will be equal to ?name=jon&country=us
2. '.slice (1)' skips the '?', returning the rest of the string. 3 .split("&")[0] splits it into two strings (?name=jon and country=us) and takes first one
3. .split("=")[1] splits name=jon into name and jon and takes the second one. Done!
