In APEX it is sometimes nice to disable a button once the user has clicked it. This can help prevent over enthusiastic users clicking the button more than once.

It is quite simple to do and you only have to paste a simple piece of JavaScript into the Button's "Button Display Attributes".

The following image shows the JavaScript within the "Attributes" :




The required code is :

onmouseup="this.disabled=true;doSubmit('IMPORT');"

As the user releases their mouse button the button is disabled. The "doSubmit" command is required to complete the submit as disabling the button prevents the standard submit from firing.

In this example the Button request value is "IMPORT and is stated in both the JavaScript above and the Button's "Button Request" attribute.
