javascript - Regex remove all special characters except numbers?

Question

I would like to remove all special characters (except for numbers) from a string. I have been able to get this far

var name = name.replace(/[^a-zA-Z ]/, "");

but it seems that it is removing the first number and leaving all of the others.

For example:

name = "collection1234"; //=> collection234

or

name = "1234567"; //=> 234567

Answer 1

Use the global flag:

var name = name.replace(/[^a-zA-Z ]/g, "");
                                    ^

If you don't want to remove numbers, add it to the class:

var name = name.replace(/[^a-zA-Z0-9 ]/g, "");
