How can i implement validation on ckeditor to prevent user from adding spaces only . Any answer within today will be greatly appreciated .
following
Since you are evidently using jQuery, you can add jQuery.trim() as an additional check for your condition:
jQuery.trim(editor_val).length != 0
This will trim all whitespace from the submitted form and check whether there are any characters remaining. If the input consists only of whitespace, the statement will evaluate to false
. You would integrate it into the following line:
if (editor_val != "" && editor_val != "" && jQuery.trim(editor_val).length != 0)
