I am searching for this every where no one is able to help me.
Only this is the one hope left for me
Below is my scenario and components I have used
* 1 file browse button - To select file
* 2 buttons
first button 1 is for validating
second button 2 is for submitting
Below is my GUI designed in Oracle APEX
Note :
On page load my submit button is disabled initially – it cannot be clicked.
On that submit button I have written PL/SQL code in backend as dynamic action
So my aim is to achieve step 3
Step 1 : I will choose file using file browse button
Step 2 : After selecting my file I will click VALIDATE button.
Once I click on validate button my dynamic action will get trigger which is written in JavaScript.
This Java script checks the file choosen is empty or not and return true or false
Sample code :
if ( file is empty )
{
return false
}
else
{
return true
}
Step 3 : Once my Validate return true my Submit button should get enabled
and After its enabled and once I click on submit button my PL/SQL code should run
I ask every one over YouTube no one as respond me
