Hello,

I have a popup window that is included in the mouse exit event, but it pops continually if you move the mouse around the area of the dropdown. How can I make it so the popup only shows 1 time and then is disabled?

Here is the code I have so far:

if (this.rawValue == "Jury Duty"){
app.alert("Please submit your jury duty summons to your Team Lead for verification.",1,0,"Jury Duty Notification Alert");
}

Thanks in advance for any insight!

There are a number of fancy things you can do with popup messages. For example, instead of an Alert box you could use a hidden text field, a timer, a some state machine logic to show the message for a short period of time.

But with your existing code the easiest solution is to use a field level variable.
if ((this.rawValue == "Jury Duty") &&  !this.bAlready){this.bAlready = true;app.alert("Please submit your jury duty summons to your Team Lead for verification.",1,0,"Jury Duty Notification Alert");}

You should also consider using a different event. The validate event for example, so the code is only called with the field value actually changes.

Since "this" is the current field object, "bAlready" is a member of the field object. At first it doesn't exist, which is interpreted as a "false" value. Then the code sets it to "true", blocking further use of the popup.

Works great! Thanks for the help. I did end up moving the code to the exit event as well.

Thanks again!
