解析查询字符串

var queryStr = "https://www.baidu.com/s?wd=%E5%90%89%E5%B0%94%E6%8B%9C%E7%99%BB&rsv_spt=1&rsv_iqid=0x8918dabe0005151c&issp=1&f=3&rsv_bp=1&rsv_idx=2&ie=utf-8&tn=baiduhome_pg&rsv_enter=1&rsv_dl=ih_0&rsv_sug3=1&rsv_sug1=1&rsv_sug7=001&rsv_sug2=1&rsv_btype=i&rsp=0&rsv_sug9=es_2_1&rsv_sug4=3943&rsv_sug=9#miaodian";
            var queryObj = parseQuery(queryStr);
			for(var key in queryObj){
				console.log(key+":"+queryObj[key]);
			}			
		   function parseQuery(queryStr){
			   var query = {};
			   var start = queryStr.indexOf("?");			   
			   var end = queryStr.indexOf("#");
			   if(start == -1){
				   return query;
			   }
			   var temp = queryStr.slice(start+1,end);
			   var queryArr = temp.split("&");
			   // for(var i=0;i<queryArr.length;i++){
				  //  var arr = queryArr[i].split("=");
				  //  //query.arr[0] = arr[1];
				  //  query[arr[0]] = arr[1];
			   // }
			   queryArr.forEach(function(item,index,arr){
				   var arr = item.split("=");
				   //query.arr[0] = arr[1];
				   query[arr[0]] = arr[1];
			   });
			   return query;
