标签:GridPanel name phone 实现 SubGrid 嵌套 Ext email view

  项目使用ext4,且建立在MVC架构上。

  实测发现以下可解,转自:(52条消息) 使用ExtJS5 GridPanel实现表格嵌套SubGrid(基于ExtJS MVC模式)_Banboll的博客-CSDN博客_extjs grid嵌套grid

  核心修改点:

  • 入口文件配置 SGEntry.js
1 Ext.application({
2     name:'SubGrid',
3     autoCreateViewport: 'SubGrid.view.SubGridMain',
4     //将视图模型加载到项目中
5     controllers:['SubGridController']
6 });
  • 视图层外层Grid SubGridMain.js 和嵌套Grid InnerGrid.js 定义

  1&2、在plugins中添加插件,和修改table

 1 Ext.define('SubGrid.view.SubGridMain', {
 2     extend : 'Ext.grid.Panel',
 3     title : 'SubGridTest',
 4     alias : 'widget.outerGrid',
 5     store : 'SubGridStore',
 6     forceFit : true,
 7     selModel : {
 8         selType: 'cellmodel',
 9         mode:'SIMPLE',
10     },
11     //该段为主表添加RowExpander插件,并指定展开区域的div标签以及类,用于承载子表
12     plugins : {
13         //指明插件類型
14         ptype : 'rowexpander',
15         //指明行展开区域
16         rowBodyTpl :["<div class='customer_expand_area_cls'>","</div>"],
17     },
18     initComponent : function() {
19         Ext.apply(this, {
20             columns : [ {
21                 header : 'Name',
22                 dataIndex : 'name',
23                 align : 'center'
24             }, {
25                 header : 'Email',
26                 dataIndex : 'email',
27                 align : 'center'
28             }, {
29                 header : 'Phone',
30                 dataIndex : 'phone',
31                 align : 'center'
32             } ]
33         });
34         this.callParent(arguments);
35     },
36 })
 1 Ext.define('SubGrid.view.InnerGrid', {
 2     extend : 'Ext.grid.Panel',
 3     alias : 'widget.innerGrids',
 4     store : 'InnerGridStore',
 5     forceFit : true,
 6     border : false,
 7     selModel : {
 8         selType: 'cellmodel',
 9         mode:'SIMPLE',
10     },
11     initComponent : function() {
12         /*
13          * 表格嵌套时必须重写Ext.view.Table,否则报错因为事件链调用的原因。
14          */
15         Ext.define('SystemFox.overrides.view.Table', {
16             override : 'Ext.view.Table',
17             checkThatContextIsParentGridView : function(e) {
18                 var target = Ext.get(e.target);
19                 var parentGridView = target.up('.x-grid-view');
20                 if (this.el != parentGridView) {
21                     return false;
22                 } else {
23                     return true;
24                 }
25             },
26             processItemEvent : function(record, row, rowIndex, e) {
27                 if (e.target && !this.checkThatContextIsParentGridView(e)) {
28                     return false;
29                 } else {
30                     return this.callParent([ record, row, rowIndex, e ]);
31                 }
32             }
33         });
34 
35         Ext.apply(this, {
36             columns : [ {
37                 text : 'Name',
38                 dataIndex : 'name',
39                 sortable : true,
40                 align : 'center'
41             }, {
42                 text : 'Email',
43                 dataIndex : 'email',
44                 sortable : true,
45                 align : 'center'
46             }, {
47                 text : 'Phone',
48                 dataIndex : 'phone',
49                 sortable : true,
50                 align : 'center'
51             },{
52                 text : 'Age',
53                 dataIndex : 'age',
54                 sortable : true,
55                 align : 'center'
56             } ,{
57                 text : 'Address',
58                 dataIndex : 'address',
59                 sortable : true,
60                 align : 'center'
61             }],
62         });
63         this.callParent(arguments);
64     },
65 })
  • 数据源层定义SubGridStore.js 和 InnerGridStore.js
 1 Ext.define('SubGrid.store.SubGridStore',{
 2     extend:'Ext.data.Store',
 3     model:'SubGrid.model.SubGridModel',
 4     data : [ {
 5         'name' : 'Lisa',
 6         "email" : "[email protected]",
 7         "phone" : "555-111-1224"
 8     }, {
 9         'name' : 'Bart',
10         "email" : "[email protected]",
11         "phone" : "555-222-1234"
12     }, {
13         'name' : 'Homer',
14         "email" : "[email protected]",
15         "phone" : "555-222-1244"
16     }, {
17         'name' : 'Marge',
18         "email" : "[email protected]",
19         "phone" : "555-222-1254"
20     } ]
21 })
 1 Ext.define('SubGrid.store.InnerGridStore',{
 2     extend:'Ext.data.Store',
 3     model:'SubGrid.model.InnerGridModel',
 4     data : [ {
 5         'name' : 'LisaInnerGridData',
 6         "email" : "[email protected]",
 7         "phone" : "555-111-1224-Inner",
 8         "age":26,
 9         "address":"Beijing"
10     }, {
11         'name' : 'BartLisaInnerGridData',
12         "email" : "[email protected]",
13         "phone" : "555-222-1234-Inner",
14         "age":26,
15         "address":"Beijing"
16     }, {
17         'name' : 'HomerLisaInnerGridData',
18         "email" : "[email protected]",
19         "phone" : "555-222-1244-Inner",
20         "age":26,
21         "address":"Beijing"
22     }, {
23         'name' : 'MargeLisaInnerGridData',
24         "email" : "[email protected]",
25         "phone" : "555-222-1254-Inner",
26         "age":26,
27         "address":"Beijing"
28     } ]
29 })
  • 模型层定义SubGridModel.js 和 InnerGridModel.js
1 Ext.define('SubGrid.model.SubGridModel', {
2     extend : 'Ext.data.Model',
3     fields:['name','email','phone']
4 })
1 Ext.define('SubGrid.model.InnerGridModel', {
2     extend : 'Ext.data.Model',
3     fields:['name','email','phone','age','address']
4 })
  • 最后控制层定义SubGridController.js

  3、添加事件监听

 1 Ext.define('SubGrid.controller.SubGridController', {
 2     extend : 'Ext.app.Controller',
 3     stores : [ 'SubGridStore', 'InnerGridStore' ],
 4     models : [ 'SubGridModel', 'InnerGridModel' ],
 5     views : [ 'SubGridMain', 'InnerGrid' ],
 6     init : function() {
 7         this.control({
 8             //监听主表视图对应事件,注意该事件并非grid panel的事件,而是Ext.view.Table对应事件
 9             //而RowExpander的事件会发送到grid panel view来监听执行,所以必须获取grid panle的gridview 来实现监听
10             'outerGrid gridview' : {
11                 expandbody : this.rowExpandEventAction,
12                 collapsebody:this.rowCollapseBodyAction
13             }
14         });
15     },
16     //展开子表
17     rowExpandEventAction : function(rowNode, record, expand_area, eopts) {
18         //创建子表,关于创建组件的方法,有很多,比如new ,或者create(),或者Ext.create(),在开发过程中具体选择哪种方式
19         //依赖于业务需求,自己判断,比如此时我要实现创建一个组件并渲染到指定区域,最简单的便是直接通过Ext.create来实现
20         //我们已定义组件因为我们需要添加额外的配置属性,倘若不需要添加,直接get**View().create()便可
21         Ext.create('SubGrid.view.InnerGrid', {
22             renderTo : expand_area.getElementsByClassName('customer_expand_area_cls')[0]
23         }).show();
24     },
25     //收起子表
26     rowCollapseBodyAction:function(rowNode, record, expand_area, eOpts){
27         //销毁子表时,我们仅需销毁组件渲染到的区域,那么该区域下的内容也会自动销毁
28         var div_expand=expand_area.getElementsByClassName('customer_expand_area_cls')[0];
29         div_expand.removeChild(div_expand.firstChild);
30     }
31 });
