使用示例：

復制代碼代碼如下:

 
var qs = new QueryString(query); 
qs.set("ajaxids", ids) 
qs.set("ajaxsn", new Date()) 
query = qs.toStr(); 

也可以連續調用：

復制代碼代碼如下:

 
query = new QueryString(query).set("ajaxids", ids).set("ajaxsn", new Date()).toStr(); 

其它用法就自己看代碼琢磨吧。
完整代碼：

復制代碼代碼如下:

QueryString = function(qs){ 
    this.p={}; 
    if(!qs) 
        url=location.search; 
    if(qs) { 
        var b = qs.indexOf('?'); 
        var e = qs.indexOf('#'); 
        if(b >= 0){ 
            qs = e < 0 ? qs.substr(b + 1) : qs.substring(b + 1,e); 
            if(qs.length > 0){ 
                qs = qs.replace(//+/g, ' '); 
                var a = qs.split('&'); 
                for (var i = 0; i < a.length; i++) { 
                    var t = a[i].split('='); 
                    var n = decodeURIComponent(t[0]); 
                    var v = (t.length == 2) ? decodeURIComponent(t[1]) : n; 
                    this.p[n] = v; 
                } 
            } 
        } 
    } 
    this.set = function(name, value){ 
        this.p[name] = value; 
        return this; 
    }; 
    this.get = function(name, def){ 
        var v = this.p[name]; 
        return (v != null) ? v : def; 
    }; 
    this.has = function(name) { 
        return this.p[name] != null; 
    }; 
    this.toStr = function() { 
        var r='?'; 
        for (var k in this.p) { 
            r += encodeURIComponent(k) + '=' + encodeURIComponent(this.p[k]) + '&'; 
        } 
        return r; 
    }; 
};
