Difference between validate(), valid() and val()

I am trying to find a bug where calling "value() != true" is causing strange behavior. And am trying to find what additional things would get called (by the jQuery library) as a result, to find the bug.

Any suggestion about how to find out?

Please elaborate.

Is there any method called value() that you are using? or this is a typo and you are actually using the val() only?
Lee SavidgeCommented:
validate() sets up the relevant exception handlers on the form. You must call this before using valid().


valid() returns true or false and is used to validate form elements


Val() is nothing to do with validation. It gets the value from a form element.


Post your code so I can see what you've got so far.

val() returning anything not null, empty string undefined or 0 will be true.
