关于验证的问题 [英] A question about validate
问题描述
我的asp.net表单上有三个webcontrol：一个TextBox，一个提交按钮
和一个RegularExpressionValidator。我已经将RegularExpressionValidator的ControlToValidate属性
设置为TextBox。但现在，当我在文本框中输入
字符串并按Enter键时，表单提交时没有
客户端javascript验证。
为什么？在提交表单之前我应该怎么做才能启用客户端验证
按Enter键或点击提交按钮？
谢谢！
There are three webcontrol on my asp.net form: a TextBox, a submit button
and a RegularExpressionValidator. And I had set ControlToValidate property
of the RegularExpressionValidator to the TextBox. But now, when I input a
string in the textbox and press Enter key, the form was submit without
client javascript validate.
Why? And what should I do to enable client validate before submit the form
whethe press Enter key or click Submit button?
Thanks!

当您说提交按钮时，请执行此操作你的意思是< input type =" submit"> ？如果是这样，那么ASP.NET如何知道单击该按钮以便它可以进行
客户端验证的时候怎么样？
尝试使用< asp：Button>并查看是否能解决问题。

When you say a Submit button, do you mean <input type="submit"> ? If so, how
would ASP.NET know when that button is clicked so that it can do the
client-side validation?
Try using an <asp:Button> and see if that fixes the problem.

否，所有控件都是服务器端Web控件，以下是我的
代码在WebPage1.aspx中：
<％@ Page language =" c＃" Codebehind =" WebForm1.aspx.cs"

No, all of the control are server side web control, and the following is my
code in WebPage1.aspx:
<%@ Page language="c#" Codebehind="WebForm1.aspx.cs"
AutoEventWireup="false" Inherits="web1.WebForm1" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>WebForm1</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name="vs_defaultClientScript" content="JavaScript">
<meta name="vs_targetSchema"
content="http://schemas.microsoft.com/intellisense/ie5">
</HEAD>
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<FONT face="??ì?">
<asp:TextBox id="TextBox1" style="Z-INDEX: 101; LEFT: 48px; POSITION:
absolute; TOP: 56px" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator id="RegularExpressionValidator1"
style="Z-INDEX: 103; LEFT: 216px; POSITION: absolute; TOP: 56px"
runat="server" ErrorMessage="RegularExpressionValidator"
ControlToValidate="TextBox1"
ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:Reg
ularExpressionValidator>
<asp:Button id="Button1" style="Z-INDEX: 102; LEFT: 144px; POSITION:
absolute; TOP: 96px" runat="server"
Text="Button"></asp:Button></FONT>
</form>
</body>
</HTML>
我的目标是数据应该是如果他们被提交到服务器
那边有效。但如果我按Enter键
而不是提交按钮，数据将在验证前提交。
My goal is that the data should be valid if they are submitted to the server
side. But the data will be submitted before validate if I press Enter key
instead of submit button.
