What do you mean by "onError" handler? wrapping everything in a large
try-catch block?




Maybe this kind of block?

function valid_dt() {
 try {
        var myFrom    = document.getElementById("blackout_add_from");
        var myThru    = document.getElementById("blackout_add_to");
        var myMessage = document.getElementById("blackout_add_delta");

        if (myFrom.value < document.blackouts.cust_dt.value) {
                myMessage.value = "Error: selected blackout dates are invalid";
                return false;
        }

        if (myThru.value < myFrom.value) {
                myMessage.value = "Error: selected blackout dates are invalid";
                return false;
        }

 function ValidateData(myData,type) {
          var test;
          if (type == 0) {
                  test = "FROM";
          } else {
                  test = "THRU"
          }
        
        myMonthDays = new Array(0,31,28,31,30,31,30,31,31,30,31,30,31);
        // 1=Year, 2=Month, 3=Day, 4=HH, 5=MM
        var splitDate  = /^(\d{4})\-(\d{2})\-(\d{2})\s(\d{2})\:(\d{2}).*/;
        var myDateA = splitDate.exec(myData);
        if (!(myDateA && myDateA.length != 5)) { // Did the RE bomb?
                myMessage.value = "Error: selected blackout dates are invalid";
                return false;
        }

        }
        myDays  = myMonthDays[myDateA[2]];

        if (myDateA[3] == 29 && myDateA[2] == 2) {
                if ( (myDateA[1] % 4 == 0) && ( (!(myDateA[1] % 100 == 0)) ||
(myDateA[1] % 400 == 0)) ) {
                        // Leap Year
                } else {

        return true;

        if ((ValidateData(myFrom.value,0) && ValidateData(myThru.value,1))) {
                return true;
        } else {
                return false;
        }

 } catch(e) {
