Use Mixins in ExtJS4 to implement multiple inheritance. The specific example code is as follows:

Copy Code code 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.
