[Wikiwyg-dev] Switch mode only if different

[Jean-Nicolas GEREONE <jean-nicolas.gereone@st.com>]

Hi,

I would like to send a very little fix but it'sis important for my 
configuration.

When you are in edit mode the user is allowed  to switch mode. But if 
the user click on the same mode that he is editing the entire algorithm 
is executed. So, if the mode to switch is the same than the current mode 
it's not necessary to convert.

That's why I've changed In wikiwyg.js : proto.switchMode :

--------------------------------------------------------------
proto.switchMode = function(new_mode_key) {
   var new_mode = this.mode_objects[new_mode_key];
   var old_mode = this.current_mode;

   if (old_mode == new_mode )
     return;

   var self = this;
   new_mode.enableStarted();
   old_mode.disableStarted();
   old_mode.toHtml(
       function(html) {
           self.previous_mode = old_mode;
           new_mode.fromHtml(html);
           old_mode.disableThis();
           new_mode.enableThis();
           new_mode.enableFinished();
           old_mode.disableFinished();
           self.current_mode = new_mode;
       }
   );
}

--------------------------------------------------------------


I've added  :

if (old_mode == new_mode )
     return;


 I hope it will be useful.


Cheers.

Jean-Nicolas.
