Replace all unwanted characters with a regular expression - how?

Question

Greetings,

I need to replace all characters in a string that are not numeric or alpha.  I've got a test string that is "Nissay Dowa General-Happy".  I need to change the string so that it becomes "NissayDowaGeneralHappy".  The JavaScript that I have created removes only the first space, resulting in "NissayDowa General-Happy".  The regular expression I am using is shown below.  Can someone tell me how to do it the right way, removing all spaces and the dash character?

mystring = "Nissay Dowa General-Happy";

regexp = /[^A-Za-z0-9]/;

newstring = mystring.replace(regexp, "");

alert(newstring);

Gracias!

Answer 1

Hi,

regexp = /[^A-Za-z0-9]/g;

should do it.

Good luck,

You may want to try \D \W (not digit, not character), include \S if you want "not white space"
