[英]ExtJs: How to use plugin within defined component in MVC architecture?
[英]How to access plugin in ExtJs MVC
我正在嘗試使用“添加新記錄”按鈕向我的網格添加工具欄。
Sencha提供的代碼示例如下:
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...
});
示例: http : //dev.sencha.com/deploy/ext-4.1.0-gpl/examples/grid/row-editing.html
因為我使用MVC模式,所以我無法將其應用於我的代碼。 這是我的代碼:
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...
});
如何訪問“rowEditing”插件以調用它所需的方法?
按鈕中的處理程序獲取對按鈕的引用作為第一個參數。 您可以將該引用與componentquery一起使用,以獲取對包含它的網格面板的引用。 gridPanel有一個getPlugin方法,您可以使用該方法根據pluginId獲取插件。您唯一需要確保的是給插件一個pluginId,否則Grid無法找到它。 這應該工作:
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...
});
干杯,羅布
編輯:添加完整示例: - 轉到http://docs.sencha.com/extjs/4.2.2/extjs-build/examples/grid/row-editing.html - 打開javascript控制台 - 將以下代碼粘貼到那里
它將創建第二個網格,其中包含一個按鈕,用於查找行編輯插件並取消編輯。 雙擊一行開始編輯,單擊tbar中的按鈕取消它。 奇跡般有效。 確保已指定pluginId,否則網格的getPlugin方法無法找到它。
