Remove Substring in Javascript

Question

In JavaScript, I need to find a substring between &J= and Key using regex and remove it from my url which could contain several substrings.

Here is my url:

SID=18608202881669&Act=432&Mode=1&CLk=T&Key58=6003&dotnetdll=TopCoConfigurator.dll&dotnetfunc=CasingSizeSummary&SID=18608202881669&F=&J=CasingSize/CasingSizeSummary.asp&Key58=6003&ccs_casingsizeid=6003

Thanks

What have you tried so far? SO is not "can someone please write a regex for me". — connexo, Aug 11 '15 at 06:45
You should try this to find all substrings b/w &J= and Key / (?<=\S)&(.*?)(?=Key) /g — Suraj Rajput, Aug 11 '15 at 07:26

You can learn Regular Expression here and code for your problem is: Here you go:

    SID="18608202881669&Act=432&Mode=1&CLk=T&Key58=6003&dotnetdll=TopCoConfigurator.dll&dotnetfunc=CasingSizeSummary&SID=18608202881669&F=&J=CasingSize/CasingSizeSummary.asp&Key58=6003&ccs_casingsizeid=6003";

var re = /&J=(.*?)&Key/;
SID = SID.replace(re, '');
alert(SID);
