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;
}
if (myDateA[4] < 0 || myDateA[4] > 23 || myDateA[5] < 0 || myDateA[5] >
59) {
myMessage.value = "Error: selected blackout dates are invalid";
return false;
}
if (myDateA[2] < 1 || myDateA[2] > 12) {
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 {
myMessage.value = "Error: selected blackout dates are
invalid";
return false;
}
} else {
if (myDateA[3] > myDays) {
myMessage.value = "Error: selected blackout dates are
invalid";
return false;
}
}
// End of ValidateData function ...
return true;
}
if ((ValidateData(myFrom.value,0) && ValidateData(myThru.value,1))) {
return true;
} else {
return false;
}
} catch(e) {
// Disable the update!
myMessage.value = "Parse Error!";
