Subject: [ cf-dev ] OT: Preventing infinite alert loop in form field
validation
Just gonna try this on CFDev cause this is urgent, you're fast off the
mark and JS-Jive are a sleepy lot...
If you're doing form validation in consecutive fields where the error
displays an alert and puts focus back on the offending field, what's the
"best" way of preventing the browser from getting into an infinite loop
where it keeps alerting the error message?
Not the real code, but the gist is something like this:
function(field) {
if (isNaN(field.value)) {
alert("Please enter a number.");
field.focus();
}
}
<input type="" onBlur="isNumber(this);">
<input type="" onBlur="isNumber(this);">
If neither of the fields have content, you
- tab off field one
- focus goes to field two
- validation for field one kicks in, alerts the error and puts focus on
field one
- the onBlur event on the second field fires
- which fails the validation test, putting focus on field one, ad
nauseam.
Thanks!
