我又回来了另一个问题......我有一个页面，顶部有一个网格面板（带有单元格编辑），下面有一个选项卡式面板，每个选项卡内都调用不同的网格面板......
我的问题是我试图让选项卡内的网格面板随着用户在顶部面板中逐行点击而改变......我知道这可能是一个监听器/处理程序的事情，但我很难找到一个有效的例子......
首先，这是顶部网格面板的代码（我认为侦听器/处理程序需要去的地方：
var pluginExpanded = true;
var grid = Ext.create('Ext.grid.Panel', {
height: 350,
width: 700,
title: 'Manufacturer URL Listing with info',
store: store,
tools: [{
type: 'save',
tooltip: 'Save Data',
// hidden:true,
handler: function (event, toolEl, panel) {
// refresh logic
//rowEditing.cancelEdit();
var sm = grid.getSelectionModel();
Ext.Msg.show({
title: 'Update Data',
msg: 'Are you sure you want to update the item information?',
buttons: Ext.Msg.YESNO,
icon: Ext.Msg.QUESTION,
fn: function (btn) {
if (btn === 'yes') {
store.update();
//store.sync();
store.load();
//Ext.getCmp(grid).getView().refresh();
}
}
});
}
}],
columns: [{
dataIndex: 'id',
flex: 1,
text: 'ID',
hidden: true
}, {
dataIndex: 'part_no',
flex: 1,
text: 'Part Number',
editor: 'textfield'
}, {
dataIndex: 'tddb_retail',
flex: 1.3,
text: 'TD Retail',
editor: 'textfield'
}, {
dataIndex: 'tddb_jobber',
flex: 1.3,

}, {

flex: 1,
text: 'Description',
editor: 'textfield'
}, {
dataIndex: 'tddb_category',
flex: 1,
text: 'Category',
editor: 'textfield'
}, {
dataIndex: 'tddb_subcategory',
flex: 1,
text: 'Sub Category',
editor: 'textfield'
}, ],
forceFit: true,
selType: 'cellmodel',
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1
})],
//paging bar
bbar: Ext.create('Ext.PagingToolbar', {
store: store,
pagesize: 15,
displayInfo: true,
displayMsg: 'Displaying items {0} - {1} of {2}',
emptyMsg: "No items to display",
}),
renderTo: Ext.getBody(),
});
