JavaScript QueryString parsing class code_javascript skills

Usage example:

Copy code The code is as follows:

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

can also be called continuously:

Copy code The code is as follows:

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

You can use it yourself for other uses Let’s look at the code and figure it out.
Full code:

Copy code The code is as follows:

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);
                                                                                                                                                     for (var I = 0; i & lt; a.Length; i) {
var T = a [i] .split ('='); ]);
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]) '&';
