Alert is not working

Avatar

Level 3

Hi there!

I have some Numeric Fields in which the user has to enter a number whithin a given range, I want that if the user enters a number that is outside the range, an alert is displayed and after that the focus is set on the same field. Also I need that the user has to be able to left the field empty.

So far I have the following code

form1.Subform4.NumericField11::exit - (JavaScript, client)

if (this.rawValue < 3 || this.rawValue > 7 && !(this.rawValue == "")){

          app.alert("Values is outside the allowable range")

          this.rawValue = "";

          xfa.host.setFocus("form1.Subform4.NumericField11");

}

If the user enters a number outside the range the alert is displayed and the Focus is set to the same field so he can enter s correct number. But if the user left the field empty the alert is displayed anyways.

Any ideas?

Thanks!

This works fine:

appAlert.jpg

if (this.rawValue < 4.5 || this.rawValue > 7 ){

          if (this.rawValue != null){

                    app.alert("Values is outside the allowable range");

                    this.rawValue = null;

                    xfa.host.setFocus("this");

          }

}

Or with the syntax of Kyle:

if (this.rawValue < 4.5 || this.rawValue > 7 ){

          if (!this.isNull){

                    app.alert("Values is outside the allowable range");

                    this.rawValue = null;

                    xfa.host.setFocus("this");

          }

}

Kind regards Mandy

I also tried, but is not working

if (this.rawValue < 4.5 || this.rawValue > 7 ){

          if (this.rawValue != ""){

                    app.alert("Values is outside the allowable range");

                    this.rawValue = "";

                    xfa.host.setFocus("form1.Subform4.NumericField14");

          }

}

Can you keep the alert message out side of the If loop and check whether you are getting the message or not.

If you are getting then your if loop might be failing then check script syntax.

To test for null (espcially for numeric fields), you need to replace the empty string test this.rawValue!="" with !this.isNull
