1、表单
对于传统的b/s应用来说，数据录入元素是放在表单<form>标签里面的。而对于ExtJS应用来说，则可以直接使用FormPanel控件来存放表单中的元素。FormPanel继承自Panel，在Panel的基础上提供与表单相关的各种特性，比如可以指定表单提交的url、指定表单提交方式、是否是二进制提交等；另外FormPanel固定使用form布局，前面关于布局一节中的内容我们说过，form布局也就是专门用于组织包含输入元素的布局。
看下面的代码：
1 Ext.onReady(function() {
2 Ext.QuickTips.init();
3
4 var bd = Ext.getBody();
5
6 /*
7 * ================ Simple form =======================
8 */
9 bd.createChild({tag: ‘h2‘, html: ‘Form 1 - Very Simple‘});10
11 var required = ‘<span style="color:red;font-weight:bold" data-qtip="Required">*</span>‘;
12
13 var simple = Ext.widget({
14 xtype: ‘form‘,
15 layout: ‘form‘,
16 collapsible: true,//折叠
17 id: ‘simpleForm‘,
18 url: ‘save-form.php‘,//将会通过AJAX请求提交到此URL
19 frame: true,//在此，这个属性就很重要了，如果不为true，你会看到下面的button和panel看起来是分开的
20 title: ‘Simple Form‘,
21 bodyPadding: ‘5 5 0‘,
22 width: 350,
23 fieldDefaults: {
24 msgTarget: ‘side‘,
25 //指定表单中字段标签的宽度
26 labelWidth: 75
27 //labelAlign来指定字段标签的对齐方式
28 },
29 defaultType: ‘textfield‘,// Ext.form.TextField （文本框）
30 items: [{
31 fieldLabel: ‘First Name‘,
32 afterLabelTextTpl: required,
33 name: ‘first‘,
34 allowBlank: false
35 },{
36 fieldLabel: ‘Last Name‘,
37 afterLabelTextTpl: required,
38 name: ‘last‘,
39 allowBlank: false
40 },{
41 fieldLabel: ‘Company‘,
42 name: ‘company‘
43 }, {
44 fieldLabel: ‘Email‘,
45 afterLabelTextTpl: required,
46 name: ‘email‘,
47 allowBlank: false,
48 vtype:‘email‘
49 }, {
50 fieldLabel: ‘DOB‘,
51 name: ‘dob‘,
52 xtype: ‘datefield‘// Ext.form.DateField （日期控件）
53 }, {
54 fieldLabel: ‘Age‘,
55 name: ‘age‘,
56 xtype: ‘numberfield‘,// Ext.form.NumberField （只能输入数字的文本框）
57 minValue: 0,
58 maxValue: 100
59 }, {
60 xtype: ‘timefield‘,// Ext.form.TextField （文本框）
61 fieldLabel: ‘Time‘,
62 name: ‘time‘,
63 minValue: ‘8:00am‘,
64 maxValue: ‘6:00pm‘
65 }],
66
67 buttons: [{
68 //保存
69 text: ‘Save‘,
70 handler: function() {
71 this.up(‘form‘).getForm().isValid();
72 }
73 },{
74 //重置
75 text: ‘Cancel‘,
76 handler: function() {
77 this.up(‘form‘).getForm().reset();
78 }
79 }]
80 });
81
82 simple.render(document.body);
83 });

2、复选框
Ext.onReady(function() {
Ext.QuickTips.init();
var bd = Ext.getBody();
bd.createChild({tag: ‘h2‘, html: ‘Form 2 - Adding fieldsets‘});
var fsf = Ext.widget({
xtype: ‘form‘,
id: ‘fieldSetForm‘,
collapsible: true,//折叠
url: ‘save-form.php‘,
frame: true,
title: ‘Simple Form with FieldSets‘,
bodyPadding: ‘5 5 0‘,
width: 350,
fieldDefaults: {
msgTarget: ‘side‘,
labelWidth: 75
},
defaults: {
anchor: ‘100%‘
},
items: [{
xtype:‘fieldset‘,
checkboxToggle:true,//关键参数，其他和以前的一样，使得选择复选框后，内容显示出来，否则不显示，默认为false，不显示复选框
title: ‘User Information‘,
defaultType: ‘textfield‘,
collapsed: true,
layout: ‘anchor‘,
defaults: {
anchor: ‘100%‘
},
items :[{
fieldLabel: ‘First Name‘,
afterLabelTextTpl: required,
name: ‘first‘,
allowBlank:false
},{
fieldLabel: ‘Last Name‘,
afterLabelTextTpl: required,
name: ‘last‘
},{
fieldLabel: ‘Company‘,
name: ‘company‘
}, {
fieldLabel: ‘Email‘,
afterLabelTextTpl: required,
name: ‘email‘,
vtype:‘email‘
}]
},{
xtype:‘fieldset‘,
title: ‘Phone Number‘,
collapsible: true,//折叠
defaultType: ‘textfield‘,
layout: ‘anchor‘,
defaults: {
anchor: ‘100%‘
},
items :[{
fieldLabel: ‘Home‘,
name: ‘home‘,
value: ‘(888) 555-1212‘
},{
fieldLabel: ‘Business‘,
name: ‘business‘
},{
fieldLabel: ‘Mobile‘,
name: ‘mobile‘
},{
fieldLabel: ‘Fax‘,
name: ‘fax‘
}]
}],
buttons: [{
text: ‘Save‘
},{
text: ‘Cancel‘
}]
});
fsf.render(document.body);
});

3、HTML编辑组件xtype: ‘htmleditor‘,
提供一个轻量的HTML编辑器组件。一些工具栏特性不被Safari浏览器支持，在必要的时候会自动的隐藏。这些不支持的特性在配置项的适当地方会有提示。
这个编辑器的工具栏按钮的提示条被定义在buttonTips属性里，但是它们默认是无效的， 除非全局的Ext.tip.QuickTipManager 属性是 已经初始化的.
编辑器作为一个敏感组件，不能被用在那些可以使用标准表单项的地方。 将编辑器放到一个display属性被设置为‘none‘的元素中时，在Safari和Firefox下面会出现问题，
因为它们在重新加载默认iframe的时候存在bug。
1 xtype: ‘htmleditor‘, 2 name: ‘bio‘, 3 fieldLabel: ‘Biography‘, 4 height: 200, 5 anchor: ‘100%‘

4、可选面板

4 var bd = Ext.getBody();
5
6 bd.createChild({tag: ‘h2‘, html: ‘Form 4 - Forms can be a TabPanel...‘});
7
8 var tabs = Ext.widget({
9 xtype: ‘form‘,
10 id: ‘tabForm‘,
11 width: 350,
12 border: false,
13 bodyBorder: false,
14 fieldDefaults: {
15 labelWidth: 75,
16 msgTarget: ‘side‘
17 },
18 items: {
19 xtype:‘tabpanel‘,
20 activeTab: 0,
21 defaults:{
22 bodyPadding: 10,
23 layout: ‘anchor‘
24 },

65 },{

68 },{
69 fieldLabel: ‘Mobile‘,
70 name: ‘mobile‘
71 },{
72 fieldLabel: ‘Fax‘,
73 name: ‘fax‘
74 }]
75 }]
76 },
77
78 buttons: [{
79 text: ‘Save‘,
80 handler: function() {
81 this.up(‘form‘).getForm().isValid();
