Ask a Jedi: Flash Forms and Acting on Drop Downs

A reader asks:

Not sure this is quite normal, but I have a CF Form, flash format, that based on options selected, submit to different action pages.

My Question is, do you know how to access and modify the "action" attribute of a CFForm using ActionsScript from a function in '<cfformitem type="script">' function?

It may very well be possible to change the action of a Flash Form. However, I wasn't sure of how to do that, so I simply used the onsubmit method. Consider the following code block:

<cfform format="flash" width="200" height="200" onsubmit="return goURL()">
&lt;cfformitem type="script"&gt;
function goURL() {
	var url = destination.value.toString();
	return false;

&lt;cfselect name="destination"&gt;
&lt;option value=""&gt;CFLib&lt;/option&gt;
&lt;option value=""&gt;ColdFusion Cookbook&lt;/option&gt;
&lt;option value=""&gt;My Blog&lt;/option&gt;

&lt;cfinput type="submit" value="Go There!" name="submit" /&gt;


This relatively simple block of code does a few things. First, it specifies an action to take on form submission. Notice I used "return goURL()" instead of just "goURL()", this was because I wanted the default form submission to not fire. My goURL() function is contained with a script form item block. This is only allowed in ColdFusion 7.0.1. The ActionScript code simply grabs the value of the form below it (which will be a URL), and then calls getURL() to load it.
