Hi goru,

var c=this;

That is used to bind client script and server script within a widget.

 

example:-

c.server.update - here controller is used to update the server script from client script.

mark it as correct/helpful if you find it helpful.

Hi Goru

 

There is a lot of significance for "this" keyword. It may vary depends on situation where it is used. It refers to the client script object.

you can assign "this" to any javascript variable.
