SharePoint 2003 PreSaveAction() to make attachment required

Question

I asked this question in the main SOF forum but I think it belongs here.

https://stackoverflow.com/questions/10415929/sharepoint-2003-presaveaction

I need to add a little JavaScript to run when user clicks "Save and Close". I know in SharePoint 2010 I could just use PreSaveAction() but I am using 2003.

Pseudo:

user clicks save and close
if attachment exists
  add the list entry
else 
  alert the user to upload attachment

It looks like the function ClickOnce() is what triggers the form to save since the button href="javascript:ClickOnce()". So what I did was change the href of this link to my own function unless attachment exists. This did not work because it would either do nothing or fire when the page loaded whether there was an attachment or not.

Anyone have a workaround for this?

Answer 1

You could use jQuery to change the HREF on the save button to first call your javascript and then call the ClickOnce() function.

Something like:

href="javascript:YourFunction();ClickOnce();"
