Replace the special character and space from the string in javascript

Question

I have a below string. I need to remove all the special character and space.

var Uid = "s/Information Needed1-s84102-p306";

I tried the below code.It didn't replace the space from the string.

console.log(Uid.replace(/[^\w\s]/gi, '')}")

The output is:- sInformation Needed1s84102p306

I want the output as sInformationNeeded1s84102p306

Please clarify if _ should be removed or not.

Simply try using

/[\W_]/g

\W match any non-word character [^a-zA-Z0-9_]

Included _ if you also want to remove it then

You can just use:

console.log(Uid.replace(/\W+/g, '')}")

\W will match any non-word character including a space.

you don't actually need the +, right? since you have the g.

Even if g flag + is good for efficiency purpose as more than one non-word characters get replaced in one go.

You can use this expression for your case

var x = "s/Information Needed1-s84102-p306";
console(x.replace(/[^A-Z0-9]/ig, ""));

Interesting, this solution might turn out better if _ should be removed too.
