/\W/ is a nice shortcut, but it excludes the space.

I used this for alphanumeric and space input only.

EXAMPLE

function checkAlphanumeric(v) {
var regex=/^[0-9a-zA-Zs' ']+$/; //^[a-zA-z' ']+$/
if(regex.test(v.value)){
return true;
} else {
alert(lng.js_req_alphanumeric)
return false;
}
}

And for the form input onKeyUp=”return checkAlphanumeric(this)”

Very helpful, thanks. Though restricting character input for passwords is a little silly, and rather insecure.

Since it is regex, wont /\W/ work just as well?

“For mixed text and numbers, with spaces /^[0-9a-zA-Zs]+$/”

This does not work !

Here is the correct one :

/^[0-9a-zA-Z\s]+$/”

BTW, thanks for your article that saved us bunch of hours !
