ASP.NET中对表单输入行有选择验证_a

好,下面我们来测试一下我们的代码,先在region name中输入一个值,如china,并提交,输出如下:

可以看到,这个时候,我们没有输入开始日期和结束日期,但系统没有提示出错信息,同样道理,只输入开始日期和结束日期,而不输入region name,也不会有提示出错信息。

程序的主要代码如下:

DisableClientValidation.aspx:

<form id="Form1" method="post" runat="server">

<TABLE id="Table1" cellSpacing="0" cellPadding="0" width="504"

align="center" borderColorLight="#996633" border="1">

<TR>

<TD style="FONT-WEIGHT: bold" align="center" colSpan="3">Region Wise Reports</TD>

</TR>

<TR>

<TD>Region Name</TD>

<TD>

<asp:TextBox id="txtRegionName" runat="server"></asp:TextBox></TD>

<TD>

<asp:RequiredFieldValidator id="rvRegion" runat="server" ControlToValidate="txtRegionName" ErrorMessage="Region is required"></asp:RequiredFieldValidator></TD>

</TR>

<TR>

<TD></TD>

<TD></TD>

<TD>

<asp:Button id="cmdRegion" runat="server" Text="Get Report"></asp:Button></TD>

</TR>

</TABLE>

<br>

<br>

<TABLE id="Table2" cellSpacing="0" cellPadding="0" width="504" border="1"

align="center" borderColorLight="#996633">

<TR>

<TD style="FONT-WEIGHT: bold" align="center" colSpan="3">Date Wise Reports</TD>

</TR>

<TR>

<TD>Start Date</TD>

<TD>

<asp:TextBox id="txtStartDate" runat="server"></asp:TextBox></TD>

<TD>

<asp:RequiredFieldValidator id="rvStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Start Date is required"></asp:RequiredFieldValidator></TD>

</TR>

<TR>

<TD>End Date</TD>

<TD>

<asp:TextBox id="txtEndDate" runat="server"></asp:TextBox></TD>

<TD>

<asp:RequiredFieldValidator id="rvEndDate" runat="server" ControlToValidate="txtEndDate" ErrorMessage="End Date is required"></asp:RequiredFieldValidator></TD>

</TR>

<TR>

<TD style="WIDTH: 139px"></TD>

<TD></TD>

<TD>

<asp:Button id="CmdDate" runat="server" Text="Get Report"></asp:Button></TD>

</TR>

</TABLE>

</form>

<script language="javascript">

function disableScript()

{

for(i=0;i< Page_Validators.length;i++)

{

//Page_Validators[i].isvalid=true;

ValidatorEnable(Page_Validators[i], false)

}

}

function enableRegionValidators()

{

for(i=0;i< Page_Validators.length;i++)

{

ValidatorEnable(Page_Validators[i], false)

}

ValidatorEnable(rvRegion, true)

}

function enableDateValidators()

{

for(i=0;i< Page_Validators.length;i++)

{

ValidatorEnable(Page_Validators[i], false)

}

ValidatorEnable(rvStartDate, true)

ValidatorEnable(rvEndDate, true)

}

</script>

<asp:Label id="lblReport" style="Z-INDEX: 101; LEFT: 144px; POSITION: absolute; TOP: 344px"

runat="server" Width="344px" Height="24px"></asp:Label>

DisableClientValidation.aspx:.cs主要代码:

private void Page_Load(object sender, System.EventArgs e)

{

cmdRegion.Attributes.Add("onclick","enableRegionValidators();");

CmdDate.Attributes.Add("onclick","enableDateValidators();");

}

private void cmdRegion_Click(object sender, System.EventArgs e)

{

rvStartDate.IsValid=true;

rvEndDate.IsValid=true;

lblReport.Text = "Region Wise Report For " + txtRegionName.Text.ToUpper();

}

private void CmdDate_Click(object sender, System.EventArgs e)

{

rvRegion.IsValid=true;

lblReport.Text = "Date Wise Report Betwee " + txtStartDate.Text.ToUpper() + " And " + txtEndDate.Text.ToUpper();

}
