JavaScript QueryString解析類代碼

來源:互聯網
上載者:User

使用樣本:
複製代碼 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: 複製代碼 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: 複製代碼 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;
};
};
