Use Mixins in ExtJS4 to implement multiple inheritance.  The specific example 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 that the difference between mixins and extend is that extend can only implement single inheritance because the arguments followed by extend can only be a string of strings, and cannot be separated by commas and so on. In Mixins, multiple classes can be loaded to achieve multiple inheritance effects.
