javascript - 如何在 ExtJs MVC 中访问插件

Question

我正在尝试使用“添加新记录”按钮将工具栏添加到我的网格。

Sencha提供的代码示例在这里:

var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', {
        clicksToMoveEditor: 1,
        autoCancel: false
    });

    // create the grid and specify what field you want
    // to use for the editor at each column.
    var grid = Ext.create('Ext.grid.Panel', {
        store: store,
        tbar: [{
            text: 'Add Employee',
            iconCls: 'employee-add',
            handler : function() {
                rowEditing.cancelEdit();

                // Create a model instance
                var r = Ext.create('Employee', {
                    name: 'New Guy',
                    email: 'new@sencha-test.com',
                    start: new Date(),
                    salary: 50000,
                    active: true
                });

                store.insert(0, r);
                rowEditing.startEdit(0, 0);
            }
        }],
        //etc...
    });

由于我使用 MVC 模式，因此无法将其应用于我的代码。这是我的代码:

Ext.define('RateManagement.view.Grids.AirShipmentGrid', {
    extend: 'Ext.grid.Panel',
    xtype: 'AirShipmentGrid',
    plugins: [
        {
            clicksToMoveEditor: 1,
            autoCancel: false,
            ptype: 'rowediting'
        },
        'bufferedrenderer'
    ],
    tbar: [{
            text: 'Add Rate',
            //iconCls: 'rate-add',
            handler : function() {
                rowEditing.cancelEdit(); // rowEditing is not defined...

                // Create a model instance
                var r = Ext.create('Employee', {
                    name: 'New Guy',
                    email: 'new@sencha-test.com',
                    start: new Date(),
                    salary: 50000,
                    active: true
                });

                store.insert(0, r);
                rowEditing.startEdit(0, 0); // rowEditing is not defined...
            }
        }],
    // etc...
});

如何访问“rowEditing”插件以调用它所需的方法？

Answer 1

来自按钮的处理程序获取对按钮的引用作为第一个参数。您可以将该引用与组件查询一起使用，以获取对包含它的网格面板的引用。 gridPanel 有一个 getPlugin 方法，您可以使用该方法根据 pluginId 获取插件。唯一需要确保的是为插件提供 pluginId，否则 Grid 无法找到它。这应该有效:

Ext.define('RateManagement.view.Grids.AirShipmentGrid', {
    extend: 'Ext.grid.Panel',
    xtype: 'AirShipmentGrid',
    plugins: [
        {
            clicksToMoveEditor: 1,
            autoCancel: false,
            ptype: 'rowediting',
            pluginId: 'rowediting'
        },
        'bufferedrenderer'
    ],
    tbar: [{
            text: 'Add Rate',
            //iconCls: 'rate-add',
            handler : function(button) {
                var grid = button.up('gridpanel');
                var rowEditing = grid.getPlugin('rowediting');
                rowEditing.cancelEdit(); // rowEditing is now defined... :)

                // Create a model instance
                var r = Ext.create('Employee', {
                    name: 'New Guy',
                    email: 'new@sencha-test.com',
                    start: new Date(),
                    salary: 50000,
                    active: true
                });

                store.insert(0, r);
                rowEditing.startEdit(0, 0); // rowEditing is not defined...
            }
        }],
    // etc...
});

编辑:添加完整示例:- 转至 http://docs.sencha.com/extjs/4.2.2/extjs-build/examples/grid/row-editing.html- 打开javascript控制台- 将下面的代码粘贴到那里

它将创建第二个网格，其中包含一个按钮，用于查找行编辑插件并取消您的编辑。双击一行开始编辑，单击 tbar 中的按钮取消它。奇迹般有效。请确保您已指定 pluginId，否则网格的 getPlugin 方法无法找到它。

Ext.require([
    'Ext.grid.*',
    'Ext.data.*',
