Clear button for specific checkboxes in a form

Hello.

 

I am new to Javascript in PDF documents.

I have a form with multiple checkboxes set in specific areas.

I created a button that I want to uncheck all buttons in a specific area.

I named the buttons "Potential#0-4" (Potential1, Potential2, etc.).

I found a javascript that I wanted to change all Checkboxes to "unchecked" when clicked (mouse up), but when I press the button, nothing happens:

function unCheckAll () {
var oAll = this.getField("Potential");
var aAll = oAll.getArray();
for(var i = 0; i < aAll.length; i++)
{
aAll.value = "Off";
}
}

unCheckAll();

 How can I make the button uncheck all checkboxes with "Potential" in their name?

 

Thank you!

To use the "getArray()" function the fields must be named using group notation. 

For example:"Potential.check1", "Potential.check2", etc.

Do this and then you can use this one line of code to reset the checkboxes

 

this.resetForm("Potential");

    Try this:

     

    for (var i = 0; i <=4; i++) {
    var f = this.getField("Potential"+i);
	f.value = "Off";
}
