注意：这个地方官方有bug，官方发布了解决方案。代码如下。

<table style="width:426.1pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> Ext.override(Ext.form.DateField, { &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;initDisabledDays : function(){ &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(this.disabledDates){ &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var&nbsp;dd = this.disabledDates; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;var&nbsp;re = "(?:"; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for(var&nbsp;i = 0; i &lt; dd.length; i++){ &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;re += this.formatDate(dd[i]); &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(i != dd.length-1) re += "|"; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;this.ddMatch = new&nbsp;RegExp(re + ")"); &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;} &nbsp;&nbsp; }); </td> 
 </tr> 
 </tbody> 
</table>

示例五：设置禁止选择的星期。

<table style="width:426.1pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> new&nbsp;Ext.form.DateField({ id:"date", fieldLabel:"选择日期", maxValue:"12/31/2009", minValue:"01/01/2009", maxText:"日期不能大于{0}", minText:"日期不能小于{0}", format:"Y年m月d日", width:200, disabledDates:["2009年05月21日"], disabledDatesText :'禁止选择该日期', disabledDays : [0,6],//禁止选择星期日和星期六 disabledDaysText : '禁止选择星期六和星期日' }) </td> 
 </tr> 
 </tbody> 
</table>

Hidden隐藏域。

<table style="width:426.1pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> Ext.onReady( function() { Ext.BLANK_IMAGE_URL = "../Ext/resources/images/default/s.gif"; Ext.QuickTips.init(); &nbsp; var&nbsp;formPanle = new&nbsp;Ext.FormPanel({ renderTo:"TestHidden", title:"formPanel", width:400, height:300, labelSeparator:"：", labelAlign:"right", frame:true, items:[ new&nbsp;Ext.form.TextField({ name:'userName', width : 150, fieldLabel:'姓名' }), new&nbsp;Ext.form.Hidden({ //隐藏域 name:'age', width : 150, fieldLabel:'年龄' }), new&nbsp;Ext.form.TextField({ name:'sex', width : 150, fieldLabel:'性别' }) ] }); } ); </td> 
 </tr> 
 </tbody> 
</table>

FieldSet，可以用来将表单组件进行分组。

<table style="width:426.1pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> Ext.onReady( function() { Ext.BLANK_IMAGE_URL = "../Ext/resources/images/default/s.gif"; Ext.QuickTips.init(); &nbsp; var&nbsp;formPanle = new&nbsp;Ext.FormPanel({ renderTo:"TestFieldSet", title:"formPanel", width:400, height:300, labelSeparator:"：", labelAlign:"right", frame:true, items:[ new&nbsp;Ext.form.FieldSet({ title:"用户信息", height:100, collapsible:true, items:[ new&nbsp;Ext.form.TextField({ name:"username", fieldLabel:"用户名" }), new&nbsp;Ext.form.TextField({ name:"password", inputType:"password", fieldLabel:"密码" }) ] }), new&nbsp;Ext.form.FieldSet({ title:"高级信息", height:100, collapsible:true, items:[ new&nbsp;Ext.form.TextField({ name:"name", fieldLabel:"姓名" }) ] }) ] }); } ); </td> 
 </tr> 
 </tbody> 
</table>

vtype属性，可以用来设置一个常用的校验规则，如邮箱，网址等。

示例：

<table style="width:426.1pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:426.1pt;"> Ext.onReady( function() { Ext.BLANK_IMAGE_URL = "../Ext/resources/images/default/s.gif"; Ext.QuickTips.init(); &nbsp; var&nbsp;formPanle = new&nbsp;Ext.FormPanel({ renderTo:"TestVtype", title:"formPanel", width:400, height:300, labelSeparator:"：", labelAlign:"right", frame:true, items:[ new&nbsp;Ext.form.TextField({ fieldLabel:'电子邮件', vtype:'email', vtypeText:"请输入正确的电子邮件格式" }), new&nbsp;Ext.form.TextField({ fieldLabel:'网址', vtype:'url', vtypeText:"请输入正确的网址" }), new&nbsp;Ext.form.TextField({ fieldLabel:'字母', vtype:'alpha', vtypeText:"请输入正确的字母" }), new&nbsp;Ext.form.TextField({ fieldLabel:'字母和数字', vtype:'alphanum', vtypeText:"请输入正确的字母和数字" }) ] }); } ); </td> 
 </tr> 
 </tbody> 
</table>
