js获取路径后面传递的参数

//将路径拆分，获取其后面传递的参数function getKeyValue(url,name){var paraString = url.substring(url.indexOf("?")+1,url.length).split("&");var data = new Dictionary();for(var i=0;i<paraString.length;i++){data.put(paraString[i].split("=")[0],paraString[i].split("=")[1]);}return data.get(name);} function Dictionary(){this.data = new Array();this.put = function(key,value){this.data[key] = value;};this.get = function(key){return this.data[key];}this.remove = function(key){this.data[key]=null;}this.isEmpty = function(){return this.data.length == 0;}this.size = function(){return this.data.length;}}
