Extjs 4 nest grid or sub grid demo

Extjs 4 nest grid or sub grid demo

grid的嵌套用到插件rowexpander，ext4.2.2.1144版本官方有这个插件。

实现重点

一：nest grid不能响应很多事件，否则会发生异常进入到函数 getHeaderIndex: function (header) 。

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

二：column定义时增加属性 menuDisabled : true,resizable:false，防止一些看起来不符合常理界面表现。

subgrid.js

Ext.define(‘Company‘, {
    extend: ‘Ext.data.Model‘,
    fields: [
            { name: ‘id‘ },
            { name: ‘company‘ },
            { name: ‘price‘, type: ‘float‘ },
            { name: ‘change‘, type: ‘float‘ },
            { name: ‘pctChange‘, type: ‘float‘ },
            { name: ‘lastChange‘, type: ‘date‘, dateFormat: ‘n/j h:ia‘ },
            { name: ‘industry‘ },
            { name: ‘desc‘ }
         ]
});

var dummyDataForMainGrid = [
        [‘1‘, ‘3m Co‘, 71.72, 0.02, 0.03, ‘9/1 12:00am‘, ‘Manufacturing‘],
        [‘2‘, ‘Alcoa Inc‘, 29.01, 0.42, 1.47, ‘9/1 12:00am‘, ‘Manufacturing‘],
        [‘3‘, ‘Altria Group Inc‘, 83.81, 0.28, 0.34, ‘9/1 12:00am‘, ‘Manufacturing‘],
        [‘4‘, ‘American Express Company‘, 52.55, 0.01, 0.02, ‘9/1 12:00am‘, ‘Finance‘]
