非常相似的问题

这是我的Grid代码（请注意在网格中声明的注释侦听器工作正常）

Ext.define( 'Fast.view.sales.SalesForecastDealersGrid ' ,{
    extend: 'Ext.grid.Panel',
    alias : 'widget.SalesForecastDealersGrid' ,
    selModel: Ext.create( 'Ext.selection.CheckboxModel' ),// sm,
    requires:[ 'Ext.toolbar.Paging'],
    columnLines: true,
    store: 'sales.SalesForecastDealers', //'sales.ProductByAccount',

    columns: [{text: 'Dealer Id',hidden: true ,flex:1,dataIndex:'dealerId' },
              {text: 'Customer Name',flex:1,sortable: true,dataIndex: 'dealerName' },
              {text: 'Sales Ids',hidden: true,flex:1,sortable: false ,dataIndex:'salesIds' }],

       initComponent: function () {

        this .dockedItems = [
        {
            xtype: 'pagingtoolbar' , dock:'bottom' ,
            store: 'sales.SalesMonthFct' ,//localStore,
            displayInfo: true ,
            displayMsg: 'Displaying ProductByAccount {0} - {1} of {2}' +'&nbsp &nbsp &nbsp',
            emptyMsg: "No ProductByAccount to display"
        }];
        this .callParent(arguments);
       } /*,
listeners:{
        selectionchange : function(model, records) {
       // var records = grid.getSelectionModel().getSelection();
       alert('section changed handler');
    }}*/    

});

和控制器

Ext.define( 'Fast.controller.sales.SalesForecastController', {
    extend: 'Ext.app.Controller',

    stores: ['sales.SalesWeekFct' ,'sales.SalesMonthFct' ,'sales.SalesForecastDealers' ],
    models: [ 'sales.SalesWeekFctModel', 'sales.SalesMonthFctModel' ],
    views: ['sales.SalesForecastWeeklyGrid' ,'sales.SalesForecastMonthlyGrid' ,'sales. SalesForecastDealersGrid' ],
    refs: [{ref: 'SalesForecastWeeklyGrid',selector: 'SalesForecastWeeklyGrid' }
          ,{ref: 'SalesForecastMonthlyGrid' ,selector: 'SalesForecastMonthlyGrid' }
          ,{ref: 'SalesForecastDealersGrid ',selector: 'SalesForecastDealersGrid '}
          ],

       init: function () {
    this .control({
    //'SalesForecastDealersGrid [action=change]': {selectionchange: this.dealerSelectionChange},
    'SalesForecastDealersGrid ': {selectionchange: this .dealerSelectionChange}
    });
    },

    dealerSelectionChanged : function (model, records) {
    //var records = grid.getSelectionModel().getSelection();
       alert( 'Controllers section changed handler' );
    }
});

正如您所注意到我已评论过＆＃34;＆＃39; SalesForecastDealersGrid [action = change]＆＃39;：{selectionchange：this.dealerSelectionChange}，＆＃34;因为我找不到任何关于这个＆＃39; [action = change]＆＃39;在我的情况下它根本不会发射任何东西。

当我点击网格行时，使用我的代码

我在控制台中收到错误消息

TypeError: listener.fireFn is undefined
...listener && listener.fireFn.apply(listener.scope || me.observable, args) === fal...

知道我接下来可以尝试什么吗？

提前谢谢。

Answer 1

您的控制器没有功能：

selectionchange: this .dealerSelectionChange

因为您的函数名称是：

dealerSelectionChanged : function (model, records)

ExtJs 4.1 TypeError：控制器中的grid selectionchange事件的'listener.fireFn is undefined'
