Answer 1

work around for finding more than one decimal dot in a field having decimal value. Cannot find the regression.
You can use the following code:

function checkDot(textVal) {
    var amount = textVal.val();
    var dots = amount.split(".").length;
    if (dots > 2) {

        return false;
    } else {
        return true;
    }
}
