The Froala editor component has many settings available at initialisation, including the placeholder.
However, I have a case where I must change the placeholder after initialisation.
I cannot see in the API docs any method to do this. I tried looking for a method on the Froala object via console.logging() it, but there is some obscurification that makes this unclear.
I tried:
$("<selector>").froalaEditor.placeholder("new value...");
and
$("<selector>").froalaEditor.({placeholder : "new value..."});
I am not posting a working snippet because this is not a coding issue specifically, but I can do if anyone believes it would be substantially useful.
Time is pressing so I would accept a jquery solution outside the manufacturers API for now.
