JS/jQuery 获取url参数js代码：function GetQueryString(name)var reg = new RegExp(“(|&)”+ name +”=(&*)(&|$)”);var r = window.location.search.substr(1).match(reg);if (r!=null) return unescape(r2); return null;URL的参数&参数名1=XXXX&参数名 2=XXXX&参数名3=XXXXalert(GetQueryString(“参数名1);alert(GetQueryString(” 参数名2);alert(GetQueryString(“参数名3);jquery 代码：把下面代 码。放到js文件中/* jQuery.query Query String Modification and Creation for jQuery* Written by Blair Mitchelmore (blair DOT mitchelmore AT gmail DOT com)* Licensed under the WTFPL (/wtfpl/).* Date: 2009/8/13* author Blair Mitchelmore* version 2.1.6*/new function(settings) / Various Settingsvar $separator = settings.separator | &;var $spaces = settings.spaces = false ? false : true;var $suffix = settings.suffix = false ? ” : ;var $prefix = settings.prefix = false ? false : true;var $hash = $prefix ? settings.hash = true ? “#” : “?” : “”;var $numbers = settings.numbers = false ? false : true;jQuery.query = new function() var is = function(o, t) return o != undefined & o != null & (!t ? o.constructor = t : true);var parse = function(path) var m, rx = /(*)/g, match = /(+?)(.*)?$/.exec(path), base = match1, tokens = ;while (m = rx.exec(match2) tokens.push(m1);return base, tokens;var set = function(target, tokens, value) var o, token = tokens.shift();if (typeof target != object) target = null;if (token = “”) if (!target) target = ;if (is(target, Array) target.push(tokens.length = 0 ? value : set(null, tokens.slice(0), value); else if (is(target, Object) var i = 0;while (targeti+ != null);target-i = tokens.length = 0 ? value : set(targeti, tokens.slice(0), value); else target = ;target.push(tokens.length = 0 ? value : set(null, tokens.slice(0), value); else if (token & token.match(/s*0-9+s*$/) var index = parseInt(token, 10);if (!target) target = ;targetindex = tokens.length = 0 ? value : set(targetindex, tokens.slice(0), value); else if (token) var index = token.replace(/s*|s*$/g, “”);if (!target) target = ;if (is(target, Array) var temp = ;for (var i = 0; i 0) queryString.push($hash);queryString.push(chunks.join($separator);return queryString.join(“”);return new queryObject(location.search, location.hash);(jQuery.query | ); / Pass in jQuery.query as settings object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(testy1);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=d
