我有ascx页面,我有一个网格,我已经添加了单选按钮,我想检查至少应该检查一个复选框,然后再卸载页面或点击btn save。
<asp:GridView ID="grdTest" runat="server" DataKeyNames="Id" AutoGenerateColumns="False" HorizontalAlign="Center" GridLines="None" onrowcreated="grdTest_RowCreated">
<asp:TemplateField >
<ItemTemplate>
<asp:TextBox ID="txtText" Rows="10" Columns="40" runat="server" TextMode="MultiLine" Height="55px" Text='<%# Eval("Text") %>'></asp:TextBox>
<asp:Button ID="btnSave" runat="server" Text="Save" CommandName="Save"/>
<span id="checkbox">
<asp:RadioButton ID="rbtnTest" runat="server" Checked='<%# Eval("Correct") %>' TextAlign="Left" Height="28px" />
</span>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtText" Rows="10" Columns="40" runat="server" TextMode="MultiLine" />
<asp:Button ID="btnSave" runat="server" Text="Save" CommandName="Save"/>
<asp:CheckBox ID="rbtnTest" runat="server" Enabled="true" TextAlign="Left"/>
</EditItemTemplate>
</asp:TemplateField>
</asp:GridView>
这有什么可能帮助我?
答案 0 :(得分:2)
<script type="text/javascript" language="javascript">
function Validate_Checkbox()
{
var chks=document.getElementsByTagName('input');
var hasChecked = false;
for (var i = 0; i < chks.length; i++)
{
if (chks[i].checked)
{
hasChecked = true;
break;
}
}
if (hasChecked == false)
{
alert("Please select at least one checkbox..!");
return false;
}
return true;
}
</script>
在提交按钮上你必须写
OnClientClick="return Validate_Checkbox()"
