1.用脚本判断点击的是否为回车键

 <script type="text/javascript"  >
     function EnterKeyClick() {
        if (event.keyCode == 13) {
            event.keyCode = 9;
        }
    }
</script>

2.前台

<ext:FormLayout ID="FormLayout3" runat="server">
     <ext:Anchor>
           <ext:TextField ID="txtCoding" runat="server" Enabled="true" FieldLabel="知识编码" Width="260" TabIndex="7" EnableKeyEvents="true">  
     　　　　<Listeners>
           　　 　　<KeyDown Handler="EnterKeyClick();" />
     　　　　</Listeners>
     　　</ext:TextField>

     <ext:Anchor>
            <ext:TextField ID="txtDescribe" runat="server" EmptyText="请输入描述" FieldLabel="描述" Width="260" TabIndex="8" EnableKeyEvents="true">
