我在保存此表单的同时设计了一种检查形式，我必须检查是否已选中所有单选列表单选按钮，我也编写了javascript，但没有给出期望的输出，因此请帮助我。
<script type="text/javascript">
var validateradios = function () {
var icount = 0;
var grid = document.getElementById('<%=gvQuestion.ClientID %>');
alert(grid.rows.length);
for (var i = 1; i < grid.rows.length; i++) {
var row = grid.rows[i];
var targetcell = row.cells[2];
var inputs = targetcell.getElementsByTagName("input");
alert(inputs.length);
for (var j = 0; j < inputs.length; j++)
if (inputs[0].checked) {
icount++; break;
}
}
if (icount == (grid.rows.length - 1))
alert(' all rows checked');
else
alert('some rows need to be checked');
}
</script>
////Gridview code
<asp:GridView ID="gvQuestion" runat="server" AutoGenerateColumns="false" CssClass="data-grid">
<Columns>
<asp:TemplateField HeaderText="Questions">
<ItemTemplate>
<asp:Label ID="lblQuestions" runat="server" Text='<%# Eval("Questions")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lblDescription" runat="server" Text='<%# Eval("Description")%>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Opinion">
<HeaderStyle Width="150px" />
<ItemTemplate>
<asp:RadioButtonList ID="radioButtonOpinion" runat="server" RepeatLayout="Flow" AutoPostBack="false">
<%-- OnSelectedIndexChanged="radioButtonGender_SelectedIndexChanged"--%>
<asp:ListItem Value="1" Text="Strongly Disagree"></asp:ListItem>
<asp:ListItem Value="2" Text="Disagree"></asp:ListItem>
<asp:ListItem Value="3" Text="Neutral"></asp:ListItem>
<asp:ListItem Value="4" Text="Agree"></asp:ListItem>
<asp:ListItem Value="5" Text="Strongly Agree"></asp:ListItem>
</asp:RadioButtonList>
<asp:RequiredFieldValidator ID="ReqiredFieldValidator1" runat="server" ValidationGroup="s"
ControlToValidate="radioButtonOpinion" ErrorMessage="*Please select"></asp:RequiredFieldValidator>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
这是行不通的，因为我错过了之后的开合大括号
（var j = 0; j <inputs.length; j ++）{
<script type="text/javascript">
var validateradios = function () {
var icount = 0;
var grid = document.getElementById('<%=gvQuestion.ClientID %>');
alert(grid.rows.length);
for (var i = 1; i < grid.rows.length; i++) {
var row = grid.rows[i];
var targetcell = row.cells[2];
var inputs = targetcell.getElementsByTagName("input");
for (var j = 0; j < inputs.length; j++) {
if (inputs[j].checked) {
icount++; break;
}
}
}
alert(icount)
if (icount == (grid.rows.length - 1))
alert(' all rows checked');
else
alert('some rows need to be checked');
}
</script>
