Coldfusion & Javascript

[jnag]

Hello,

I have date fields on a form which is generated by a Coldfusion custom
tag (another piece of code). I want to change something else on the
form when the user changes the date. But, how do I generate an
onChange() event on this field (since I only have the call to the
custom tag in this form)?

Thanks in advance for any suggestions.

Try this JS (note: execute this line *after* the form has loaded):

document.forms['TheFormName'].elements['TheDateFieldNa me'].onclick =
whatYouWantToDo ;

It would seem to be a better idea to use the onload event of the window
to trigger a function to set it. Then you know, for sure, that it is
available for scripting.

Thank you very much for this suggestion. It works partially (in that,
before I was not able to even fire the event). But, it is implementing
the event function before the form comes up. I want it to happen when
the user changes the date. I have included this line after the
<form...tag just where the date field tag is defined. Is this
probably because the date field is part of the server side custom tag
which has already been executed? Thanks.

I think you need to put the onclick line of code much later in the page.
Try just above the /html tag at the end of the page. Or, as Randy
suggested, put it in the body onload event. By then the form will be
completely loaded and any changes the user makes will trigger your
onclick event.
