isCancelled()

Returns true if the user has pressed the Cancel button during Dashboard loading, otherwise returns false.

This function allows a long-running script to be terminated by a user Cancel action. If a script does not check the isCancelled status and self-terminate, the Dashboard cannot be canceled by user action until the script has run to completion.

Example

for(var i = 0; i < 100000 && !isCancelled(); i++) {
  // statement to execute
  // statement to execute
  //...
  // statement to execute
}
