html – 表行,你可以将高度设置为零吗？

你为什么问！那么,当用户单击父行时,我有一行动态构建和显示.麻烦的是,如果没有行,单击时,它仍然会显示一个空的1像素高排.

这是子网格视图：

<asp:TemplateField HeaderStyle-CssClass="hidden-@R_696_8620@n" ItemStyle-CssClass="hidden-@R_696_8620@n" FooterStyle-CssClass="hidden-@R_696_8620@n">
                <ItemTemplate>
                    <tr>
                        <td colspan="8" >
                            <div id='<%# Eval("PublicationID") %>' style="display: none; position: relative;">
                                <asp:GridView ID="GridView2_ABPubs" runat="server" AutoGenerate@R_696_8620@ns="false" Width="100%"
                                    DataKeyNames="PublicationID" Font-Names="Verdana" Font-Size="small">
                                    <@R_696_8620@ns>
                                        <asp:TemplateField>
                                            <ItemTemplate>
                                                <asp:checkBox ID="ChildPublicationSELEctor" runat="server" />
                                            </ItemTemplate>
                                        </asp:TemplateField>
                                        <asp:BoundField DataField="NameAbbrev" HeaderText="Publication Name" SortExpression="NameAbbrev" />
                                    </@R_696_8620@ns>
                                </asp:GridView>
                            </div>
                        </td>
                    </tr>
                </ItemTemplate>
            </asp:TemplateField>

CSS：

.hidden-@R_696_8620@n 
{
    display: none;  
}

JavaScript的：

<script language="JavaScript" type="text/javascript">
    var currentlyOpenedDiv = "";
    function CollapseExpand(object) {
        var div = document.getElementById(object);
        //if (currentlyOpenedDiv != "" && currentlyOpenedDiv != div) {
        //    currentlyOpenedDiv.style.display = "none";
        //}
        if (div.style.display == "none") {
            div.style.display = "inline";
            currentlyOpenedDiv = div;
        }
        else {
            div.style.display = "none";
        }
    }
</script>
