使用Javascript从url参数获取变量 [英] Get a variable from url parameter using Javascript

问题描述

我正在尝试使用javascript获取网址值，到目前为止，我只能获得纯数字，而不是字母或字母的混合数字。我找不到任何一个函数的工作示例，它允许检索带有字母的数字，只是数字。我没有使用任何非字母数字字符。我想要传递的示例值是42p316041610751874cm83p2306600132141。

I am trying to get a url value using javascript, so far I can only get pure numbers, not mixed numbers with letters or just letters. I can't find any working examples of a function that allows for numbers with letters to be retrieved, just numbers. I am not using any non alphanumeric characters. An example value that I am trying to pass is "42p316041610751874cm83p2306600132141".

function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
    hash = hashes[i].split('=');
    vars.push(hash[0]);
    vars[hash[0]] = hash[1];
}
return vars;
}

 var first = getUrlVars()["test"];

任何帮助都会很棒。谢谢。

Any help would be great. Thanks.

推荐答案

以下是上述两个答案的精简版本：

Here is a condensed version of two of the answers above :

function gup (name) {
  name = RegExp ('[?&]' + name.replace (/([[\]])/, '\\$1') + '=([^&#]*)');
  return (window.location.href.match (name) || ['', ''])[1];
}

更容易输入，更容易处理，恕我直言更容易阅读。 YMMV

Easier to type, easier on processing and, IMHO easier to read. YMMV
