Hi,
This is sort of a :
How to build a Yes/No dialog box qquestion.
Or perhaps a question about getting javascript variables
from a pop-up window and processing them on a submit.
This is what I'd like to have happen :
When the user clicks on the Delete button the confirm() method
should run and prompt the user for a Yes/No selection. Then
the doDelete variable should get assigned. Then the validate()
method should get called. The result of validate() should be
false if the user selected "No".
This is what happens :
confirm runs and prompts the user. The validate() method never
sees the value of doDelete.
Notice there are two forms.
Your help is appreciated. Thanks!
