Checking if form already exists

rated 0 times [ 64] [ 5] / answers: 1 / hits: 15275 / 13 Years ago, fri, november 18, 2011, 12:00:00

Is there a better command than this to check if a form is exists and if so submit it? Right now I'm using:

if(document.forms[0])document.forms[0].submit()

Which works, however if form[0] does not exist it throws an exception. I'm trying to keep this dynamic in the sense I don't know what the form ID or name is.

To avoid the exception you could do:

if (typeof document.forms[0] !== 'undefined') document.forms[0].submit();
