I have set a character limit for a Textfield.

i try to show the remaining characters without success.

alternatively i try to show an error message when the limit is reached

var laenge = this.getField("Overline").value;
event.rc = true;
if (laenge > 10)
{
     app.alert("Max. 40 characters incl. spaces");
     event.rc = false;
}
else
{
    event.target.textColor = color.black;
}

Is there a way to display the remaining characters?

if not, what am I doing wrong with the code here?

A more complex way of performing this task:

Countdown Maximum Length Input

The approach used by D.P. Story is to use the "AFMergeChange()" function to obtain the length of the form field being filled in dynamically.

Where did you place this code? Under what event?

Try this:

var laenge = this.getField("Overline").value.length;

unfortunately did not work.

i also try var laenge = this.getField("Overline").value.toString().length; without success.

Use following lines:

console.show();

var laenge = event.value.length;

console.println("laenge: " + laenge);
