100分求解：ASP.NET和数据校验

[justforfun9912]

如下一段代码是浏览器上看到的：
<TR>
<TD class="firstcol">证件类型</TD>
<TD>

对应的ASPX描述是这样的：
<TD class="firstcol">证件类型</TD>
<TD>
<ASP:RADIOBUTTONLIST id="fld_pid_type" runat="server" repeatdirection="Horizontal" repeatlayout="Flow"
enableviewstate="False">
<ASP:LISTITEM value="I">公民身份证</ASP:LISTITEM>
<ASP:LISTITEM value="T">临时身份证</ASP:LISTITEM>
<ASP:LISTITEM value="S">军官证</ASP:LISTITEM>
<ASP:LISTITEM value="P">中华人民共和国护照</ASP:LISTITEM>
<ASP:LISTITEM value="L">营业执照</ASP:LISTITEM>
<ASP:LISTITEM value="O">其他有效证件</ASP:LISTITEM>
</ASP:RADIOBUTTONLIST>
<ASP:REQUIREDFIELDVALIDATOR id="RequiredFieldValidator10" runat="server" controltovalidate="fld_pid_type" display="Dynamic"
errormessage="*" enableviewstate="False"></ASP:REQUIREDFIELDVALIDATOR></TD>
</TR>
<TR>
<TD class="firstcol">证件号码</TD>
<TD>
<ASP:TEXTBOX id="fld_pid_info" runat="server" enableviewstate="False" columns="20" maxlength="20"></ASP:TEXTBOX>
<ASP:REGULAREXPRESSIONVALIDATOR id="rgv_pid_info" runat="server" controltovalidate="fld_pid_info" display="Dynamic"

<ASP:REQUIREDFIELDVALIDATOR id="RequiredFieldValidator43" runat="server" controltovalidate="fld_pid_info" display="Dynamic"
errormessage="*" enableviewstate="False"></ASP:REQUIREDFIELDVALIDATOR></TD>
</TR>


请教：我如何在客户端添加一些JavaScript代码，使得选中证件类型＝身份证时，规则表达式校验器rgv_pid_info才起作用，而选中其他证件类型时，不需要校验是否输入了15、18个数字字符？

不懂！up

[brightheroes]

给你的RADIOBUTTONLIST 加上一个事件
当选中中证件类型！＝身份证
设置这个验证控件的enable为true

[yichuan1982]

呵呵，沾光，同意

[yichuan1982]

*.attrubute.add

[brightheroes]

在客户端处理好像不是很方便，嗯

[lr2651]

干嘛还在javascript里写啊，直接在dropdownlist的selected_change事件里写
if (dropdownlist.selecctValue != "I")
{
验证控件.Enable = false;
}
就好了

不可避免的要刷新一次

private void RadioButtonList1_SelectedIndexChanged(object sender, System.EventArgs e)
{
if(this.RadioButtonList1.SelectedItem.Text = "公民身份证")
this.RequiredFieldValidator1.Enabled = false;
}

[penning]

你可以让验证控件EnableClientScript="False"，再服务器端根据用户的选择再决定是否Validate();
MSDN的例子
<%@ Page Language="C#" AutoEventWireup="True" %>

<html>
<head>
<script runat="server">

void Button_Click(Object sender, EventArgs e)
{

Random rand_number = new Random();

Compare1.ValueToCompare = rand_number.Next(1, 10).ToString();
Compare1.Validate();

if (Page.IsValid)
{
lblOutput.Text = "You guessed correctly!!";
}
else
{
lblOutput.Text = "You guessed poorly";
}

lblOutput.Text += "<br><br>" + "The number is: " + Compare1.ValueToCompare;

}

</script>

</head>
<body>

<form runat=server>

<h3>Validator Example</h3>

<h5>Pick a number between 1 and 10:</h5>

<asp:TextBox id="TextBox1"
runat="server"/>

<asp:CompareValidator id="Compare1"
ControlToValidate="TextBox1"
ValueToCompare="0"
EnableClientScript="False"
Type="Integer"
Display="Dynamic"
ErrorMessage="Incorrect guess!!"
Text="*"
runat="server"/>

<asp:RequiredFieldValidator id="Require1"
ControlToValidate="TextBox1"
EnableClientScript="False"
Display="Dynamic"
ErrorMessage="No number entered!!"
Text="*"
runat="server"/>

<br><br>

<asp:Button id="Button1"
Text="Submit"
OnClick="Button_Click"
runat="server"/>

<br><br>

<asp:Label id="lblOutput"
Font-Name="verdana"
Font-Size="10pt"
runat="server"/>

<br><br>

<asp:ValidationSummary
id="Summary1"
runat="server"/>

</form>

</body>
</html>

你把 规则表达式校验器rgv_pid_info的功能也用js写
否则也要刷新页面

[justforfun9912]

感谢回复。我用了个很笨的办法，可以不刷新页面。
<SCRIPT language="javascript" type="text/javascript">
function check_clear (vForm, vValidator)
{
for(i=0;i<vForm.elements.length;i++)
{
e = vForm.elements[i];
if(e.type=='radio' && e.id=="UC_CustomerData1_fld_pid_type_0")
{
vValidator.enabled = e.checked;
}
}
}
</SCRIPT>

然后给这个单选列表添加一个客户端的onclick事件：
fld_pid_type.Attributes.Add ("onclick", "javascript:check_clear (Form1, UC_CustomerData1_rgv_pid_info);");

效果不是很好，但已经满足了我的需要。
