我的javascript每个问题只允许1个答案

my javascript allow only 1 answer per question

<script type="text/javascript">
    function GridSelectAllColumn(objType, chkName) {
        var oItem = objType.children;
        var theBox = (objType.type == "radio") ? objType : objType.children.item[0];
        var strPart = theBox.id.split("_");
        xState = theBox.checked;
        elm = theBox.form.elements;
        for (i = 0; i < elm.length; i++)
            if (elm[i].type == "radio" && elm[i].id != theBox.id && elm[i].id.indexOf(strPart[3]) > -1)
                elm[i].checked = !xState;
    }
</script>

我的gridview

my gridview

<asp:GridView runat="server" ID="question1"  CssClass="table table-striped table-bordered table-hover" DataKeyNames="ID" AutoGenerateColumns="false" HeaderStyle-BackColor="CornflowerBlue" HeaderStyle-Font-Bold="true" HeaderStyle-ForeColor="White" CellPadding="5">

                <asp:BoundField DataField="Code" HeaderText="Question" ItemStyle-ForeColor="White" ItemStyle-HorizontalAlign="Left" ItemStyle-BackColor="graytext" />

                <asp:TemplateField HeaderText="Low">
                    <ItemStyle HorizontalAlign="Center" />
                    <ItemTemplate>
                        <asp:RadioButton runat="server" ID="check1" onclick="javascript:GridSelectAllColumn(this, '1');" />
                    </ItemTemplate>
                </asp:TemplateField>

                <asp:TemplateField HeaderText="High">
                    <ItemStyle HorizontalAlign="Center" />
                    <ItemTemplate>
                        <asp:RadioButton runat="server" ID="check2" onclick="javascript:GridSelectAllColumn(this, '2');" />
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>

        {
            foreach (GridViewRow row in question1.Rows)
            {
                string code = row.Cells[0].Text;
                bool low = (row.FindControl("check1") as RadioButton).Checked;
                bool high = (row.FindControl("check2") as RadioButton).Checked;

            }
        }
