var RequestQuerystring; (窗口。Onpopstate = function () { var匹配, pl = /\+/g， //用空格替换加法符号的正则表达式 搜索= /([^&=]+)=?([^&]*)/g， decode =函数(s){返回decodeURIComponent(s)。替换(pl， " "));}， Query = window.location.search.substring(1); RequestQuerystring = {}; While (match = search.exec(查询)) RequestQuerystring[decode(match[1])] = decode(match[2]); })（);

RequestQuerystring现在是一个包含所有参数的对象

试试这个工作演示http://jsfiddle.net/xy7cX/

火:

inArray: http://api.jquery.com/jQuery.inArray/

这应该会有帮助:)

code

var url = "http://myurl.com?sent=yes"

var pieces = url.split("?");
alert(pieces[1] + " ===== " + $.inArray("sent=yes", pieces));

或者你可以用这个简洁的小函数，因为为什么解这么复杂?

function getQueryParam(param, defaultValue = undefined) {
    location.search.substr(1)
        .split("&")
        .some(function(item) { // returns first occurence and stops
            return item.split("=")[0] == param && (defaultValue = item.split("=")[1], true)
        })
    return defaultValue
}

当简化和联机时看起来更好:

单线解

var queryDict = {};
location.search.substr(1).split("&").forEach(function(item) {queryDict[item.split("=")[0]] = item.split("=")[1]})

result:
queryDict['sent'] // undefined or 'value'

但如果你有编码字符或多值键呢?

你最好看看这个答案:如何在JavaScript中获得查询字符串值?

偷偷高峰

"?a=1&b=2&c=3&d&e&a=5&a=t%20e%20x%20t&e=http%3A%2F%2Fw3schools.com%2Fmy%20test.asp%3Fname%3Dståle%26car%3Dsaab"
> queryDict
a: ["1", "5", "t e x t"]
b: ["2"]
c: ["3"]
d: [undefined]
e: [undefined, "http://w3schools.com/my test.asp?name=ståle&car=saab"]

> queryDict["a"][1] // "5"
> queryDict.a[1] // "5"

我希望这能有所帮助。

 <script type="text/javascript">
   function getParameters() {
     var searchString = window.location.search.substring(1),
       params = searchString.split("&"),
       hash = {};

     if (searchString == "") return {};
     for (var i = 0; i < params.length; i++) {
       var val = params[i].split("=");
       hash[unescape(val[0])] = unescape(val[1]);
     }

     return hash;
   }

    $(window).load(function() {
      var param = getParameters();
      if (typeof param.sent !== "undefined") {
        // Do something.
      }
    });
</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') { .....

还有另一种功能……

function param(name) {
    return (location.search.split(name + '=')[1] || '').split('&')[0];
}
