Currently, I am working on implementing a validation block in my JavaScript code to ensure that users have selected a value before proceeding. If a value is not selected, I want to display a pop-up message prompting them to do so.
function validate(form) {
var success = true;
var message = "";
if (form.dropdown.selectedIndex == 0) {
form.save.disabled=true;
if (0 < message.length) {
message += "\n";
}
message += "Please select a dropdown value.";
}
if (0 < message.length) {
alert(message);
success = false;
}
return success;
}
Whenever I click the Save button, this function is called. However, I haven't been able to identify any errors in the logs. Can someone please point out what I might be doing incorrectly here? Alternatively, could you provide guidance on the correct approach to validating whether a user has indeed selected a value before allowing them to save?
Thank you!
