我将直接发布代码,无需过多解释。请记住,我的 json 记录集有嵌套的 Notes 记录。在客户端,这意味着每个 Calls 记录都有一个嵌套的notesStore,其中包含相关的 Notes。另外,为了简单起见,我只显示一个 Notes 列 - 内容。
Ext.define('MyApp.view.calls.Grid', {
alias: 'widget.callsgrid',
extend: 'Ext.grid.Panel',
...
initComponent: function(){
var me = this;
...
var config = {
...
listeners: {
afterrender: function (grid) {
me.getView().on('expandbody',
function (rowNode, record, expandbody) {
var targetId = 'CallsGridRow-' + record.get('id');
if (Ext.getCmp(targetId + "_grid") == null) {
var notesGrid = Ext.create('Ext.grid.Panel', {
forceFit: true,
renderTo: targetId,
id: targetId + "_grid",
store: record.notesStore,
columns: [
{ text: 'Note', dataIndex: 'content', flex: 0 }
]
});
rowNode.grid = notesGrid;
notesGrid.getEl().swallowEvent(['mouseover', 'mousedown', 'click', 'dblclick', 'onRowFocus']);
notesGrid.fireEvent("bind", notesGrid, { id: record.get('id') });
}
});
}
},
...
};
Ext.apply(me, Ext.apply(me.initialConfig, config));
me.callParent(arguments);
},
plugins: [{
ptype: 'rowexpander',
pluginId: 'abc',
rowBodyTpl: [
'<div id="CallsGridRow-{id}" ></div>'
]
}]
});
