model-view-controller - Extjs4如何调用带参数的函数？

Question

这段代码不能正常工作：我调用一个传递变量的函数这样做的正确方法是什么？有什么建议吗？

Ext.define('DigitalPaper.view.DirTree' ,{
    extend: 'Ext.TreePanel',
    requires: ['Ext.window.MessageBox'],
    id: "DirTree",
    store: 'DirTree',
    alias : 'widget.DirTree',
    title : 'Cartelle',
    rootVisible: true,
    useArrows: true,
    scope: this,
    selectNode: undefined,

initComponent: function() {
    //HERE: 
    this.assocFolderColumnset(id);

    this.callParent(arguments);
}

,assocFolderColumnset: function (id){
    console.log(id);
}

});

Answer 1

更正代码

this.assocFolderColumnset(this.id);

并在 assocFolderColumnset

,assocFolderColumnset: function (id){
    this.id = id;
    console.log(id);
}
