Regex for allowing alphanumeric and space

Question

I am searching for a regular expression for allowing alphanumeric and spaces in JavaScript. I tried Googling but wasn't able to find that. For alphanumeric i am using '^[a-zA-Z0-9]+$'

Can anyone help me out with this?

Thanks in advance.

Beginning or end, doesn't matter. Just add it in the list (or the expression). – Dexterians Aug 05 '20 at 06:49

You might be surprised but you literally only had to add a space in between the square brackets like so:

'^[a-zA-Z0-9 ]*$'

RegExp is challenging but I have found a resource by google that can be quite helpful here.
