extjs4使用itemselecor时要修改源码才能实现toStore

initComponent: function() {
    var me = this;

    me.ddGroup = me.id + '-dd';
    me.callParent();

    // bindStore must be called after the fromField has been created because
    // it copies records from our configured Store into the fromField's Store
    //me.bindStore(me.store);       //don't need to bind
},

createList: function(title, store){     //add a parameter named store
...
store: store,       //use the passed store
...
}
...
me.fromField = me.createList(me.fromTitle, me.store);
me.toField = me.createList(me.toTitle, me.toStore);

 

 

以上是ItemSelector.js修改后的样子，

 

有空再整理我的实例发上来

 

参考文章，帮了我大忙!
