How to add onsubmit type functionality to forms?

I'm scratching my head a bit here on the best way to add onsubmit-type handling to forms in Share.  I have a custom control that is a WYSIWYG editor and I'd like to copy the contents of the editor out to the standard content form field textarea on the inline-edit page before running through the normal validation/submit procedure.

I can see a few different ways to do it but wondered what the Alfresco-recommended way is. Here are my ideas so far:

• Update the contents every n milliseconds using setTimeout (not my favourite because it introduces potential race conditions)
• Add a custom validation method that simply copies the text between the two and returns true
• Add an event listener to the form that copies the data when the form is submitted (using Alfresco.util.ComponentManager.get(myFormId))
• Add an event listener to copy the data when the editor loses focus

Are one of these a better approach than another or is there yet another way that I'm missing?

Cheers,

Ryan

I think there is another better way you can try, the forms runtime has a function that allows you to get called back just before submission, it gets called after validation has completed however, so it may not work for you.

The function I mentioned is called "doBeforeFormSubmit", there are a few examples of it being used throughout Share just search for it's use across the JS files.

Hope that helps!
