function GET() {
        var data = [];
        for(x = 0; x < arguments.length; ++x)
            data.push(location.href.match(new RegExp("/\?".concat(arguments[x],"=","([^\n&]*)")))[1])
                return data;
    }


example:
data = GET("id","name","foo");
query string : ?id=3&name=jet&foo=b
returns:
    data[0] // 3
    data[1] // jet
    data[2] // b
or
    alert(GET("id")[0]) // return 3

下面是String原型实现：

String.prototype.getParam = function( str ){
    str = str.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regex = new RegExp( "[\\?&]*"+str+"=([^&#]*)" );    
    var results = regex.exec( this );
    if( results == null ){
        return "";
    } else {
        return results[1];
    }
}

示例调用：

var status = str.getParam("status")

str可以是查询字符串或url

如果您不想使用JavaScript库，可以使用JavaScript字符串函数来解析window.location。将此代码保存在外部.js文件中，您可以在不同的项目中反复使用它。

// Example - window.location = "index.htm?name=bob";

var value = getParameterValue("name");

alert("name = " + value);

function getParameterValue(param)
{
    var url = window.location;
    var parts = url.split('?');
    var params = parts[1].split('&');
    var val = "";

    for ( var i=0; i<params.length; i++)
    {
        var paramNameVal = params[i].split('=');

        if ( paramNameVal[0] == param )
        {
            val = paramNameVal[1];
        }
    }
    return val;
}

function GetQueryStringParams(sParam)
{
    var sPageURL = window.location.search.substring(1);
    var sURLVariables = sPageURL.split('&');

    for (var i = 0; i < sURLVariables.length; i++)
    {
        var sParameterName = sURLVariables[i].split('=');
        if (sParameterName[0] == sParam)
        {
            return sParameterName[1];
        }
    }
}​

假设URL为

http://example.com/?stringtext=jquery&stringword=jquerybyexample

var tech = GetQueryStringParams('stringtext');
var blog = GetQueryStringParams('stringword');

如果需要数组样式参数，URL.js支持任意嵌套的数组样式参数以及字符串索引（映射）。它还处理URL解码。

url.get("val[0]=zero&val[1]=one&val[2]&val[3]=&val[4]=four&val[5][0]=n1&val[5][1]=n2&val[5][2]=n3&key=val", {array:true});
// Result
{
    val: [
        'zero',
        'one',
        true,
        '',
        'four',
        [ 'n1', 'n2', 'n3' ]
    ]
    key: 'val'
}

<script type="text/javascript" language="javascript">
    $(document).ready(function()
    {
        var urlParams = {};
        (function ()
        {
            var match,
            pl= /\+/g,  // Regular expression for replacing addition symbol with a space
            search = /([^&=]+)=?([^&]*)/g,
            decode = function (s) { return decodeURIComponent(s.replace(pl, " ")); },
            query  = window.location.search.substring(1);

            while (match = search.exec(query))
                urlParams[decode(match[1])] = decode(match[2]);
        })();

        if (urlParams["q1"] === 1)
        {
            return 1;
        }
    });
