Question

If the user press enter key, it should behave as he is pressing the esc key.

function OnEditorKeyPress(editor, e) {
    if (e.htmlEvent.keyCode == 13) {
        e.htmlEvent.keyCode = 27;
        //treeList.CancelEdit();
    }
}

But the value 13 remains same after e.htmlEvent.keyCode = 27; this statement also. How to assign a new value or any other alternative method is there to do this?

Answer 1

These properties of the event object are read only (including KeyCode), so you can’t do such of thing. Why you can’t do something like this?

function OnEditorKeyPress(editor, e) {
   //If user press enter or escape
   if (e.htmlEvent.keyCode == 13 || e.htmlEvent.keyCode == 27) // correct comparison operation
   {
      treeList.CancelEdit();
      e.htmlEvent.preventDefault
   }
}
