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 ]/, \"\");
<         


        

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, "");
