Document Action will close

[M.Hasanin]

Hi ,

I'm trying to ask the user to change his mind if he didn't really want to exit from the (Opened PDF Doc),, so i go to Document Action at (Document will close) and write the following :

var cMsg = "Are you sure you want to close ?";
cMsg += "\n\n";
cMsg += "Contiunue ? \n\n ";
var nRtn = app.alert(cMsg,2,2,"Warning ! ");
if(nRtn == 4)
{// A yes Response
  // Code for doing the thing you do on a yes
  this.closeDoc();
}
else if(nRtn == 3)
{ // No Response
  //event.value = 0; // assume do nothing
  beep
  !this.closeDoc();
}
else   
{ //Unknown Response
  beep
  !this.closeDoc();
}

But the Above Code is Closing the Document even if the user hit yes or no? ho do i change it to not close the document if the user hit (No)... thanks for any tip

The script can't abort the file close command. The only way is if the user closes the file using a button you added to it, which executes this code. But if they click the X button or File - Close or Quit, the file will close, no matter what.

Thank  you

Info: !this.closeDoc(); will also close the document.

Very inventive but very wrong too! In fact it tries to close it twice (once because it’s going to close anyway and once be you call this.closeDoc.) This could even cause a crash.

! something does not mean “don’t do something” it means “do something and invert the result”.

[M.Hasanin]

it work good in a button with no crash, what do you suggest instead using !this.closeDoc()

[M.Hasanin]

“do something and invert the result”. only if you use logic operators in comparing values between two arguments

[Bernd Alheit]

This is not correct. Where did you read this?

[M.Hasanin]

i didn't, it some times happened to me when trying crazy things in Acro JS!

[Bernd Alheit]

Can you share a sample file?

[try67]

All "!" does is take a Boolean value and return it after applying the NOT logical operator on it. It does not execute (or not execute) anything by itself. You give it a value of TRUE and it will return FALSE. You give it FALSE, it will return TRUE. That's it.

[M.Hasanin]

no it doesn't if you use it in a button

[Bernd Alheit]

Remove the beep lines and you will see what happens.

[M.Hasanin]

not happened also after removing the Beep lines, I'm using Adobe Acrobat Pro DC

What code do you use now?

[M.Hasanin]

var cMsg = "Are you sure you want to close ?";  
cMsg += "\n\n";  
cMsg += "Contiunue ? \n\n ";  
var nRtn = app.alert(cMsg,2,2,"Warning ! ");  
if(nRtn == 4)  
{// A yes Response  
  // Code for doing the thing you do on a yes  
  this.closeDoc();  
}  
else if(nRtn == 3)  
{ // No Response  
  //event.value = 0; // assume do nothing  
  !this.closeDoc();  
}  
else     
{ //Unknown Response  
  !this.closeDoc();  
}

This code will always close the document.

[M.Hasanin]

OK, but what about other option available ? i mean how to do it the right way ?

To not close the file? Simply do nothing. Assuming the code is executed from a button it will just return to the file as normal.

[M.Hasanin]

The Correct Code will be :

var cMsg = "Are you sure you want to close ?";  
cMsg += "\n\n";  
cMsg += "Contiunue ? \n\n ";  
var nRtn = app.alert(cMsg,2,2,"Warning ! ");  
if(nRtn == 4)
{// A yes Response
  // Code for doing the thing you do on a yes
  this.closeDoc();
}
else if(nRtn == 3)
{ // No Response
  event.value = 0; // assume do nothing
}
else   
{ //Unknown Response
  event.value = 0; // assume do nothing
}

Lines 10-17 can be removed. A button doesn't have a value, so they don't do anything, anyway.

The Doc/WillClose event is triggered before a document is closed. However, it does not listen to the rc return code.

You won't be able to stop the document from closing.

J-

[Test Screen Name]

The clue is in the action name. It's called "Will close" not "Might close" or "Your chance to not close". Most actions with "Will" in the name are already committed.

“do something and invert the result”. only if you use logic operators in comparing values between two arguments

No, you are wrong. It inverts the result and (since it is not tested) throws it away. Where on earth did you get the idea that you can use this to cancel anything at all, still less a call already under way?

[Test Screen Name]

That seems valid but  NOT valid when run as a document-will-close action where it will not stop the document closing and might cause a crash.
