jquery 获取地址栏网址url参数(1/2)

例如 当前你的url是：
http://www.111cn.net/ ?test=1&kk=2

如果想获取test，则可以引入插件后，
用如下方法获取：
var test = $.query.get(’test’);

如果参数有多个相同的名称 ，则可以这样：
var arr = $.query.get(’testy’);
输出：  [ 值1 ,  值2,  值3...]

如果要获取多个相同名称中的某一个，可以这样：
var arrayelement = $.query.get(’testy[1]‘);

此插件不仅能获取参数，也能设置参数。

设置一个参数：
var newurl = $.query.set("section", 5).tostring();
输出  ： "?section=5"

设置两个参数：
var newurl = $.query.set("section", 5).set("action", "do").tostring();
输出 :  "?action=do&section=5"

删除一个参数：
var oldqueryagain = $.query.remove("type");

清空所有参数：
var emptyquery = $.query.empty();

复制所有参数：
var stillthesame = $.query.copy();

看一款实例

$.request = (function () {
var apimap = {};
function request(querystr) {
var api = {};
if (apimap[querystr]) {
return apimap[querystr];
}
api.querystring = (function () {
var urlparams = {};
var e,
d = function (s) { return decodeuricomponent(s.replace(/+/g, " ")); },
q = querystr.substring(querystr.indexof('?') + 1),
r = /([^&=]+)=?([^&]*)/g;
while (e = r.exec(q))
urlparams[d(e[1])] = d(e[2]);

return urlparams;
})();
api.geturl = function () {
var url = querystr.substring(0, querystr.indexof('?') + 1);
for (var p in api.querystring) {
url += p + '=' + api.querystring[p] + "&";
}
if (url.lastindexof('&') == url.length - 1) {
return url.substring(0, url.lastindexof('&'));
}
return url;
}
apimap[querystr] = api;
return api;
}
$.extend(request, request(window.location.href));
return request;
})();

来现在来看一个详细的实例

比如一条url：http://127.0.0.1/index.html?id=999&type=2
那么在index.html中这样写就可以获得id和type的值
var id=$.query.get("id");  // id=999
var type=$.query.get("type");  // type=2
