real time form validation and DHTML

[NickyJay]

Hi all,

can anyone point me in the right direction? I've been searching all day with no luck!

I have to validate 3 inputs on a form and change how the inputs are displayed if they are incorrect according to my javascript functions. I have posted this in the html/css forum also

Thanks!

Shouldn't double post, that's a no-no.

You should probably call your functions on the onsubmit attribute on the form


<form onsubmit="return functionName()">

If the inputs are "incorrect", don't validate, then alert as to what needs to be changed and return false from the function.

This will work in the case that you have a submit button.

If you submit the form with Javascript, then you must first call the validation function and there is no need for the onsubmit attribute.

Hi!

Thanks for responding - sorry but i had to double post as i didnt know where to post!

I already have an onSubmit, but i need to have on three seperate fields also, need to be able to either change the field background/text colour but not thow an alert box...

Ok, just check each of your fields in your validation function.

If you have something that is invalid in a text field, change the background color and foreground color.

I'm not sure, without seeing what code you have, exactly what your question is.
