function gup( name, url ) {
    if (!url) url = location.href;
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( url );
    return results == null ? null : results[1];
}
gup('q', 'hxxp://example.com/?q=abc')

我使用parseUri库。它允许您完全按照您的要求进行操作：

var uri = 'www.test.com/t.html&a=1&b=3&c=m2-m3-m4-m5';
var c = uri.queryKey['c'];
// c = 'm2-m3-m4-m5'

优雅、实用的解决方案

让我们创建一个包含URL参数名作为关键字的对象，然后我们可以通过其名称轻松提取参数：

// URL: https://example.com/?test=true&orderId=9381  

// Build an object containing key-value pairs
export const queryStringParams = window.location.search
  .split('?')[1]
  .split('&')
  .map(keyValue => keyValue.split('='))
  .reduce<QueryStringParams>((params, [key, value]) => {
    params[key] = value;
    return params;
  }, {});

type QueryStringParams = {
  [key: string]: string;
};


// Return URL parameter called "orderId"
return queryStringParams.orderId;

function getParamValue(param) {
    var urlParamString = location.search.split(param + "=");
    if (urlParamString.length <= 1) return "";
    else {
        var tmp = urlParamString[1].split("&");
        return tmp[0];
    }
}

无论参数是否为最后一个，这都适用于您的情况。

PHP parse_str copycat..：）

// Handles also array params well
function parseQueryString(query) {
    var pars = (query != null ? query : "").replace(/&+/g, "&").split('&'),
        par, key, val, re = /^([\w]+)\[(.*)\]/i, ra, ks, ki, i = 0,
        params = {};

    while ((par = pars.shift()) && (par = par.split('=', 2))) {
        key = decodeURIComponent(par[0]);
        // prevent param value going to be "undefined" as string
        val = decodeURIComponent(par[1] || "").replace(/\+/g, " ");
        // check array params
        if (ra = re.exec(key)) {
            ks = ra[1];
            // init array param
            if (!(ks in params)) {
                params[ks] = {};
            }
            // set int key
            ki = (ra[2] != "") ? ra[2] : i++;
            // set array param
            params[ks][ki] = val;
            // go on..
            continue;
        }
        // set param
        params[key] = val;
    }

    return params;
}

var query = 'foo=1&bar=The+bar!%20&arr[]=a0&arr[]=a1&arr[s]=as&isset&arr[]=last';
var params = parseQueryString(query);
console.log(params)
console.log(params.foo)        // 1
console.log(params.bar)        // The bar!
console.log(params.arr[0])     // a0
console.log(params.arr[1])     // a1
console.log(params.arr.s)      // as
console.log(params.arr.none)   // undefined
console.log("isset" in params) // true like: isset($_GET['isset'])



/*
// in php
parse_str('foo=1&bar=The+bar!%20&arr[]=a0&arr[]=a1&arr[s]=as&isset&arr[]=last', $query);
print_r($query);

Array
(
    [foo] => 1
    [bar] => The bar!
    [arr] => Array
        (
            [0] => a0
            [1] => a1
            [s] => as
            [2] => last
        )

    [isset] =>
)*/

正如在最新浏览器的第一个答案中提到的，我们可以使用新的URL api，然而，获取对象中的所有参数并使用它们的更一致的本地javascript简单解决方案可能是

例如，该类表示locationUtil

const locationSearch = () => window.location.search;
const getParams = () => {
  const usefulSearch = locationSearch().replace('?', '');
  const params = {};
  usefulSearch.split('&').map(p => {
    const searchParam = p.split('=');
    const [key, value] = searchParam;
    params[key] = value;
    return params;
  });
  return params;
};

export const searchParams = getParams();

用法：：现在可以在类中导入searchParams对象

url示例---https://www.google.com?key1=https://www.linkedin.com/in/spiara/&valid=true

import { searchParams } from '../somewhere/locationUtil';

const {key1, valid} = searchParams;
if(valid) {
 console.log("Do Something");
 window.location.href = key1;
}
