Resolves query parameters of a URL to a Dictionary object

There are two ways to parse the query parameters of a URL into a Dictionary object:
1. Manual parsing

1 functionGetquerystringargs (URL) {2url = URL = =NULL?Window.location.href:url;3         varQS = url.substring (Url.lastindexof ("?") + 1);4         varargs = {};5         varItems = qs.length > 0? Qs.split (' & ')) : [];6         varitem =NULL;7         varName =NULL;8         varValue =NULL;9          for(vari=0; i<items.length; i++){TenItem = items[i].split ("="); One             //use decodeURIComponent () to decode name and value separately (because the query string should be encoded).  AName = decodeURIComponent (item[0]); -Value = decodeURIComponent (item[1]); -  the             if(name.length) { -Args[name] =value; -             } -         } +  -         returnargs; +     } AConsole.log (Getquerystringargs (' Https://www.baidu.com/baidu?tn=monline_3_dg&ie=utf-8&wd=12306%E7%81%AB %e8%bd%a6%e7%a5%a8%e7%bd%91%e4%b8%8a%e8%ae%a2%e7%a5%a8%e5%ae%98%e7%bd%91 ')); at     //Object {tn: "MONLINE_3_DG", ie: "Utf-8", WD: "12306 train tickets online booking official website"}

2. Using the regular

1 functiongetqueryobject (URL) {2url = URL = =NULL?Window.location.href:url;3         varSearch = url.substring (Url.lastindexof ("?") + 1);4         varobj = {};5         varreg =/([^?&=]+) = ([^?&=]*)/G;6         //[^?&=]+ says: except? , &, = one or more characters away from7         //[^?&=]* says: except? , &, = 0 to more characters (any number)8Search.replace (Reg,function(RS, $, $) {9             varName = decodeURIComponent ($);Ten             varval = decodeuricomponent ($); Oneval =String (val); AObj[name] =Val; -             returnrs; -         }); the         returnobj; -     } -Console.log (Getqueryobject (' https://www.baidu.com/baidu?tn=monline_3_dg&ie=utf-8&wd=12306%E7%81%AB%E8% Bd%a6%e7%a5%a8%e7%bd%91%e4%b8%8a%e8%ae%a2%e7%a5%a8%e5%ae%98%e7%bd%91 ')); -     //Object {tn: "MONLINE_3_DG", ie: "Utf-8", WD: "12306 train tickets online booking official website"}
