[SOLVED] Simple form submission question

Hi,

I have what I think should be a simple question.

I'm trying to submit form details to a javascript function using onclick.

The trouble I'm having is because the form is dynamically generated using php I do not know the names of the form fields or how many there will be.

So...

what can I use to say "pass all the form fields to the function"

eg.

onclick="callfunction(myform.allfields_and_values) "


Any help would be appreciated, spent quite a lot of time searching Google for the answer.

Thanks

You could use

Code: Select all

onclick="callfunction(this.form)"

This will pass a refence to the form from which you can cycle through the inputs/elements

Code: Select all

function callFunction (theForm)
{
var inputs = theForm.getElementsByTagName('input');
var selects = theForm.getElementsByTagName('select');

//etc

for (i=0; i<inputs.length; i++)
{
    // Process the inputs
}
for (i=0; i<selects.length; i++)
{
    // Process the inputs
}

}

That allows you to cycle through without knowing the names of form elements.

Cheers

Thanks

That was exactly what I was after, cheers
