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'

// Read a page's GET URL variables and return them as an associative array.
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;
}

// Usage for URL: http://my.site.com/location?locationId=53cc272c0364aefcb78756cd&shared=false
var id = getUrlVars()["locationId"];

从这里得到：http://jquery-howto.blogspot.ru/2009/09/get-url-parameters-values-with-jquery.html

我使用

function getVal(str) {
    var v = window.location.search.match(new RegExp('(?:[\?\&]'+str+'=)([^&]+)'));
    return v ? v[1] : null;
}

    function gup() {
    var qs = document.location.search;
    qs = qs.split('+').join(' ');
    var params = {}, tokens, re = /[?&]?([^=]+)=([^&]*)/g;
    while (tokens = re.exec(qs))
        params[decodeURIComponent(tokens[1])] = decodeURIComponent(tokens[2]);
    return params;
}

像这样使用

var params = gup()

然后

params.param1
params.param2

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
        )

从许多答案中学习（如VaMoose的、Gnarf的或Blixt的）。

您可以创建一个对象（或使用Location对象）并添加一个方法，该方法允许您获取URL参数，解码后使用JS样式：

Url = {
    params: undefined,
    get get(){
        if(!this.params){
            var vars = {};
            if(url.length!==0)
                url.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value){
                    key=decodeURIComponent(key);
                    if(typeof vars[key]==="undefined") {
                        vars[key]= decodeURIComponent(value);
                    }
                    else {
                        vars[key]= [].concat(vars[key], decodeURIComponent(value));
                    }
                });
            this.params = vars;
        }
        return this.params;
    }
};

这允许只使用Url.get调用该方法。

第一次它将从url中获取对象，下次它将加载保存的对象。

实例

在url中，如？param1=param1Value&param2=param2Value&param1=param1Value2，参数的获取方式如下：

Url.get.param1 //["param1Value","param1Value2"]
Url.get.param2 //"param2Value"
