The Code is as follows:

(Function (){

Ext. onReady (function (){

Ext. define ('say ',{

CanSay: function (){

Alert ("hello ");

}

});

Ext. define ('eat ',{

Caneat: function (){

Alert ("eating ");

}

});

Ext. define ("user ",{

Mixins :{

Csay: 'say ',

Ceat: 'eat'

}

});

Var ss = Ext. create ("user ",{});

Ss. caneat ();

Ss. canSay ();

});

})();

 

Note the difference between mixins and extend. extend can only implement Single inheritance, because the parameters following extend can only be a String type, and files cannot be separated by commas.

 

In mixins, multiple classes can be loaded to achieve multi-inheritance.
