Sencha ExtJS 6 Widget Grid 入门

  最近由于业务需要,研究了一下Sencha ExtJS 6 ,虽然UI和性能上据相关资料说都有提升,但是用起来确实不太顺手,而且用Sencha cmd工具进行测试和发布,很多内部细节都是隐藏的,出了问题不好跟踪。更奇葩的是明明在sencha app watch上运行很好,但是sencha app build后会出现异常。即使是这样,但Sencha ExtJS 6 在UI控件和编程模式上确实比较强大。下面介绍一个 Widget Grid 用法,可以在表格grid中进行列样式渲染,是一个比较强大的功能:

1 拷贝admin-dashboard创建项目

2 配置app.json,主要用于中文提示和采用font-awesome字体库等

 1     /**
 2      * The Sencha Framework for this application.
 3      */
 4     "framework": "ext",
 5     "locale": "zh_CN",//中文
 6     /**
 7      * The list of required packages (with optional versions; default is "latest").
 8      * https://docs.sencha.com/extjs/6.0/core_concepts/localization.html
 9      */
10     "requires": [
11         "charts",
12         "font-awesome",//字体
13         "ux",
14         "ext-locale"
15     ],

3 配置菜单(Admin.store.NavigationTree)

1   {
2         text: 'Widget Grid',
3          view: 'main.SRFX',
4          leaf: true,
5          iconCls: 'x-fa fa-times-circle',
6          routeId: 'SRFX'
7  },

4 定义视图和模型等

 在\classic\src\view\main中新建 一个srfxd.js,其内容为:

 1 var store = Ext.create('Ext.data.Store', {
 2     fields: ['name', 'progress'],
 3     data: [
 4         { name: 'Lisa', progress: .159, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
 5         { name: 'Bart', progress: .216, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
 6         { name: 'Homer', progress: .55, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
 7         { name: 'Maggie', progress: .167, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] },
 8         { name: 'Marge', progress: .145, sequence1: [1, 2, 4, 5, 4, 5], sequence2: [1, -2, 4, 5, 4, -5], sequence3: [1, -2, 4, 5, 4, -5] }
 9     ]
10 });
11 
12 
13 
14 
15 Ext.define('Admin.view.main.SRFX', {
16     extend: 'Ext.grid.Panel',
17     requires: [
18         'Ext.grid.column.Action',
19         'Ext.ProgressBarWidget',
20         'Ext.slider.Widget',
21         'Ext.sparkline.*'
22     ],
23     title: '收入分析',
24     store: store,
25     columns: [
26         {
27             text: 'Name',
28             dataIndex: 'name'
29         },
30         {
31             text: 'progress',
32             xtype: 'widgetcolumn',
33             width: 120,
34             dataIndex: 'progress',
35             widget: {
36                 xtype: 'progressbarwidget',
37                 textTpl: [
38                     '{percent:number("0")}% done'
39                 ]
40             }
41         }
42         , {
43             text: 'Line',
44             width: 100,
45             dataIndex: 'sequence2',
46             xtype: 'widgetcolumn',
47             widget: {
48                 xtype: 'sparklineline',
49                 tipTpl: 'Value: {y:number("0.00")}'
50             }
51         }
52         , {
53             text: 'Bar',
54             width: 100,
55             dataIndex: 'sequence2',
56             xtype: 'widgetcolumn',
57             widget: {
58                 xtype: 'sparklinebar'
59             }
60         }, {
61             text: 'Bullet',
62             width: 100,
63             dataIndex: 'sequence3',
64             xtype: 'widgetcolumn',
65             widget: {
66                 xtype: 'sparklinebullet'
67             }
68         }
69     ],
70     height: 350,
71     width: 600,
72     // renderTo: Ext.getBody()
73 });
