查看此代码，并查看第20行。

See this code, and look at the line 20.

Ext.define('Boo.view.Foo.List', {
    extend: 'Ext.panel.Panel',
    model: 'Boo.model.FooModel',
    alias: 'widget.foolist',
    store: 'FooListStore',
    initComponent: function () {
        this.columns = [
            {
                text: "Hello world",
                dataIndex: 'Time',
                flex: 1
            },
            {
                xtype: 'actioncolumn',
                width: 50,
                items: [{
                    icon: 'cancel.png',
                    tooltip: 'Cancel',
                    handler: function (grid, rowIndex, colIndex, col, e) {
                        //Now I need to get the application here, for example with self.getApplication() or something like this.
                    }
                }]
        }];

        this.callParent(arguments);
    }
});

推荐答案

您可以使用 appProperty

You can archieve this using the appProperty

Ext.application({
    name: 'MyApp',
    appProperty: 'Current'
});

现在可以调用

MyApp.Current

从任何地方导致 MyApp 命名空间在窗口（全局）范围内抵抗。

from anywhere cause the MyApp namespace resist within the window (global) scope.

对于4.1.3之前的任何版本，将以下行添加到启动方法应用程序

For any Version before 4.1.3 add the following line to the Launch-Method of the Application

YourAppName[this.appProperty] = this;
