我用了这个，很管用。 http://codesheet.org/codesheet/NF246Tzs

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
    vars[key] = value;
    });
return vars;
}


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

最好的解决方案。

var getUrlParameter = function getUrlParameter(sParam) {
    var sPageURL = window.location.search.substring(1),
        sURLVariables = sPageURL.split('&'),
        sParameterName,
        i;

    for (i = 0; i < sURLVariables.length; i++) {
        sParameterName = sURLVariables[i].split('=');

        if (sParameterName[0] === sParam) {
            return sParameterName[1] === undefined ? true : decodeURIComponent(sParameterName[1]);
        }
    }
    return false;
};

这就是你如何使用这个函数假设URL是， http://dummy.com/?technology=jquery&blog=jquerybyexample。

var tech = getUrlParameter('technology');
var blog = getUrlParameter('blog');

从字符串中获取参数:

Object.defineProperty(String.prototype, 'urlParam', {

    value: function (param) {

    "use strict";

    var str = this.trim();

    var regex = "[\?&]" + param + "=([^&#]*)";

    var results = new RegExp(regex, "i").exec(str);

    return (results !== null) ? results[1] : '';

    }
});

使用方法:

var src = 'http://your-url.com/?param=value'

console.log(src.urlParam(param)); // returns 'value'

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
    vars[key] = value;
    });
return vars;
}


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

还有一个使用URI.js库的例子。

例子准确地回答了所问的问题。

var url = 'http://example.com?sent=yes'; var urlParams = new URI(url).search(true); // 1. Does sent exist? var sendExists = urlParams.sent !== undefined; // 2. Is it equal to "yes"? var sendIsEqualtToYes = urlParams.sent == 'yes'; // output results in readable form // not required for production if (sendExists) { console.log('Url has "sent" param, its value is "' + urlParams.sent + '"'); if (urlParams.sent == 'yes') { console.log('"Sent" param is equal to "yes"'); } else { console.log('"Sent" param is not equal to "yes"'); } } else { console.log('Url hasn\'t "sent" param'); } <script src="https://cdnjs.cloudflare.com/ajax/libs/URI.js/1.18.2/URI.min.js"></script>

这将给你一个很好的工作对象

    function queryParameters () {
        var result = {};

        var params = window.location.search.split(/\?|\&/);

        params.forEach( function(it) {
            if (it) {
                var param = it.split("=");
                result[param[0]] = param[1];
            }
        });

        return result;
    }

然后;

    if (queryParameters().sent === 'yes') { .....
