ExtJS4 表格的嵌套 rowExpander应用

今天做一个grid，里面的数据需要带明细，思来想去还是搞个表格嵌套吧！看下图

复制代码 代码如下:

function displayInnerGrid(renderId) {

//Model for the inside grid store
Ext.define('TestModel', {
extend: 'Ext.data.Model',
fields: [
{ name: 'Field1' },
{ name: 'Field2' },
{ name: 'Field3' }
]
});

//dummy data for the inside grid
var dummyDataForInsideGrid = [
['a', 'a', 'a'],
['b', 'b', 'b'],
['c', 'c', 'c']

];

var insideGridStore = Ext.create('Ext.data.ArrayStore', {
model: 'TestModel',
data: dummyDataForInsideGrid
});

innerGrid = Ext.create('Ext.grid.Panel', {
store: insideGridStore,
selModel: {
selType: 'cellmodel'
},
columns: [
{ text: "明细1", dataIndex: 'Field1' },
{ text: "明细2", dataIndex: 'Field2' },
{ text: "明细3", dataIndex: 'Field3' }
],
columnLines: true,
autoWidth: true,
autoHeight: true,
//width: 400,
//height: 200,
frame: false,
// iconCls: 'icon-grid',
renderTo: renderId
});

/* innerGrid.getEl().swallowEvent([
'mousedown', 'mouseup', 'click',
'contextmenu', 'mouseover', 'mouseout',
'dblclick', 'mousemove'
]); */

}


function destroyInnerGrid(record) {

var parent = document.getElementById(record.get('id'));
var child = parent.firstChild;

while (child) {
child.parentNode.removeChild(child);
child = child.nextSibling;
}

}

复制代码 代码如下:

grid_huizong.view.on('expandBody', function (rowNode, record, expandRow, eOpts) {
//console.log(record.get('id'));
displayInnerGrid(record.get('id'));
});

grid_huizong.view.on('collapsebody', function (rowNode, record, expandRow, eOpts) {
destroyInnerGrid(record);
});

复制代码 代码如下:

plugins: [{
ptype: 'rowexpander',
rowBodyTpl : [
'<div>',
'</div>'
]
}],
