Thanks but now:
This changes the response from “undefined” to “false”. It returns “false” no matter the state of the checkbox is clicked???? My project is named “Checker”, it has a check box named “checkbox1” and a text field named “textField1” along with a button that calls for javascript “CheckMe()”.
It now contains your script that I adapted:
function CheckMe(){
var x1 = $(‘Checker-checkbox1 > input’).is(‘:checked’);
document.getElementById(‘Checker-textField1’).value=(x1);
}
