How to get first query string from url in jquery using Regex? [duplicate]

Question

I have url something like this

/test/test123/e/account/data/element?bUnit=17&name=cId&formName=TestForm&value=[self]

I just want to get first querystring and replace value of it so i tried

[\?&]([^=]+)\=([^&]+)

But getting all querystrings. I already have tried, just little mistake which want to fix. Don't want multiple lines of function.

How to get only one Query string and replace?

Thanks

Can you explain what exactly you're trying to select and replace? That whole substring is indeed one query string — CertainPerformance

If you only want the first one, then why use &? Change [\?&] to [\?] and it works in your refex101 — fdomn-m

If you want to find/replace a specific parameter (which sounds much more useful than just the first), then : stackoverflow.com/questions/5999118/… (and many other already answered questions that ask the same thing) — fdomn-m

remove the first &, this should work

[\?]([^=]+)\=([^&]+)
