Reset all form fields to default value

Hello,

it is me again. 🙂

I am trying to reset a form when clicking a reset-button.

Currently i used the function resetForm(Fields) but i want to reset the fields to the default value which is given in the preferences/settings.

So i thought about looping all fields and put value to defaultValue but then my Acrobat freezes.

Previous Script:

var fieldstoteset = ["Field1", "Field2", "Field3"];
if(4==app.alert("The form will be resetted.\n\nAll data will be removed! Continue?",1,2)) {
    this.resetForm(fieldstoteset );
    this.getField("top").setFocus();
}

New Try:

if(4==app.alert("The form will be resetted.\n\nAll data will be removed! Continue?",1,2)) {
    for (var i = 0; i < this.numFields; i++) {
        var fieldname = getField(getNthFieldName(i);
        this.getField(fieldname).name).value = this.getField(fieldname).defaultValue;
    }
    this.getField("top").setFocus();
}

Many thanks in advance for your hints 🙂
