Regular Expression?

[Jastper]

Hi All, I am new to javascript and am trying to create a regular expression that will only allow numbers, letters and whitespaces (for an address field). Does anyone have any good web references that I could go to or how the expression should look?
Any tips greatefully recieved.

try this:
[tt]
function isNumLetOrSpace(s) {
return /^[a-z0-9\s]+$/gi.test(s);
}
[/tt]

usage:[tt]
var myAddress = "123 Main Street";
alert(isNumLetOrSpace(myAddress));
[/tt] =========================================================
while (!succeed) try();
