Answer 1

Another way,

$(document).ready(function() {
    HighlightControlToValidate();
    $('#<%=btnSave.ClientID %>').click(function() {
        if (typeof (Page_Validators) != "undefined") {
            for (var i = 0; i < Page_Validators.length; i++) {
                if (!Page_Validators[i].isvalid) {
                    $('#' + Page_Validators[i].controltovalidate).css("background", "#f3d74f");
                }
                else {
                    $('#' + Page_Validators[i].controltovalidate).css("background", "white");
                }
            }
        }
    });
});
