Get URL parameters quickly using JavaScript

First of all: the originalQuick tip:get URL Parameters with JavaScript

 function Getallurlparams (URL) {var queryString = URL? url.split ('? ')            [1]: Window.location.search.slice (1);            var obj = {};                if (queryString) {queryString = Querystring.split (' # ') [0];                var arr = querystring.split (' & ');                    for (var i = 0; i < arr.length; i++) {var a = arr[i].split (' = ');                    var paramnum = undefined;                        var paramname = a[0].replace (/\[\d*\]/, function (v) {ParamNum = V.slice (1,-1);                    Return ';                    }); var paramvalue = typeof (A[1]) = = = ' undefined '?                    "": a[1];                    ParamName = Paramname.tolowercase ();                    Paramvalue = Paramvalue.tolowercase (); if (Obj[paramname]) {if (typeof obj[paramname] = = = ' String ') {Obj[para                        Mname] = [Obj[paramname]];   }                     if (typeof ParamNum = = = ' undefined ') {Obj[paramname].push (paramvalue);                        } else {Obj[paramname][paramnum] = paramvalue;                    }} else {obj[paramname] = paramvalue;        }}} return obj; }

　　

It's a little bit of a change here.

      Set parameter value (use ' true ' if empty)      var paramvalue = typeof (A[1]) = = = ' undefined '? True:a[1];      (optional) Keep case consistent      paramname = Paramname.tolowercase ();      Paramvalue = Paramvalue.tolowercase ();

Optionally, you can set all parameter names and values to lowercase. That's the, can avoid situations where someone sends traffic to a URL with example=TRUE instead of and example=true your script breaks (I ' ve seen this happen). However, if your query string needs to is case sensitive, feel free to omit this part

= paramName.toLowerCase();paramValue = paramValue.toLowerCase();

In the original text, a Boolean value is returned if the Parameter object value is empty. But obviously paramvalue.tolowercase () does not allow you to do so.

The whole feeling is pretty good ~ ~
