Stopping processing inside an event

[wolftxusa]

I have a question similar to this post:

http://forums.adobe.com/message/3287875

I am inside a click event (button push) in Adobe Forms in a JavaScript routine.  I want to exit conditionally.  The above message had no repy and other searches did not find what I need.

Example in pseudo-code:

----- data.SF1.BTN_SHOW::click: - (JavaScript, client) ---------------------------------------------

var x = 1;

xfa.host.messageBox ("Before");

if (x==1) {

  return;

}

xfa.host.messageBox ("After");

If x is not 1, I want to see two popups, if it is 1 only the first one.  I tried 'return', 'exit', 'break', 'quit' (and a few other possible commands).  Since I am not inside a function, 'return' does not appear to work.

Thanks in advance.  I find the forums hard to navigate, so I hope I get an answer and find this post...

Regards,

Wolfgang

why not just rewrite the code to:

xfa.host.messageBox ("Before");

if (x<>1) {

xfa.host.messageBox ("After");

}

Thanks for your help.

Because it was just an example.  If I have 20 checks to make, I do not want to indent 20 times.  There should be a fairly simple way to stop the processing of the script similar to a 'return' or 'return false' in a function...

Any other ideas how to skip the remainder of the script inside the event?

Edit:

I found a way (although ugly) to make it work for multiple checks.  For simplicity, I added a numeric text field 'INT' to the same subform where my button is, just so I can test a few different cases... In reality, the checks can be for different and unrelated things.

----- data.SF1.Button1::click: - (JavaScript, client) ----------------------------------------------

var i = 0;

i = this.parent.INT.rawValue; // Just to set i conveniently
xfa.host.messageBox( "i = " + i );

// Dummy loop (once)

for ( var dummy = 0; dummy < 1; dummy++) {
  if( i < 1 ) { // Check 1
    xfa.host.messageBox( "i needs to be at least 1, but it is " + i );
    continue;
  }
  if( i < 3 ) { // Check 2
    xfa.host.messageBox( "i needs to be at least 3, but it is " + i );
    continue;
  }   
  if( i < 4 ) { // Check 3
    xfa.host.messageBox( "i needs to be at least 4, but it is " + i );
    continue;
  }       
   
// Checks passed
  xfa.host.messageBox( "All checks passed, i is " + i );
}
xfa.host.messageBox( "Done" );

Now everything goes to the 'Done' part of the code, but only the ones where all checks pass go to the 'All checks passed' part. Even with 20 checks I will only have one indentation which is acceptable.  If nobody finds a more elegant way to exit the click event processing when I tell it to, I will stick with this construction.  The 'continue' acts like a 'return' when inside the 'for' loop.

I hope for a prettier solution though.

Hi Wolfgang,

You can define JavaScript functions within the click event, so maybe the code below is better?

function canContinue(i)

{

  if( i < 1 ) { // Check 1

    xfa.host.messageBox( "i needs to be at least 1, but it is " + i );

    return false;

  }

  if( i < 3 ) { // Check 2

    xfa.host.messageBox( "i needs to be at least 3, but it is " + i );

    return false;

  }   

  if( i < 4 ) { // Check 3

    xfa.host.messageBox( "i needs to be at least 4, but it is " + i );

    return false;

  }       

  return true;

}

if (canContinue(this.parent.INT.rawValue))

{

    xfa.host.messageBox( "All checks passed, this.parent.INT.rawValue is " + this.parent.INT.rawValue );

}
