这里是HTML代码   <!-- 查看图片 -->
    <div id="PictureDetail" runat="server">
        <div>
            <asp:Button ID="closeButton" runat="server" Text="关闭" />
            &nbsp;&nbsp;&nbsp;&nbsp;
            <asp:Button ID="setCover" runat="server" Text="设为相册封面" OnClick="setCoverButtonClick" />
            <!-- 图片id，隐藏不显示 -->
            <asp:TextBox ID="pictureId" runat="server"></asp:TextBox>
        </div>
        <div>
            <asp:Table BorderColor="2" runat="server">
                <asp:TableHeaderRow runat="server">
                </asp:TableHeaderRow>
                <asp:TableRow runat="server">
                    <asp:TableCell ID="TableCell1" HorizontalAlign="Center" runat="server">
                        <div id="showImg">
                            <asp:Image ID="img" CssClass="showPicture" runat="server" /></div>
                    </asp:TableCell>
                </asp:TableRow>
                <asp:TableRow runat="server">
                    <asp:TableCell runat="server">
                        <asp:Label ID="Label1" runat="server" Text="标题："></asp:Label>
                        <asp:TextBox ID="title" runat="server"></asp:TextBox>
                    </asp:TableCell>
                </asp:TableRow>
                <asp:TableRow runat="server">
                    <asp:TableCell ID="TableCell3" runat="server">
                        <asp:Label ID="Label2" runat="server" Text="信息："></asp:Label>
                        <asp:TextBox ID="info" runat="server"></asp:TextBox>
                    </asp:TableCell>
                </asp:TableRow>
                <asp:TableRow runat="server">
                    <asp:TableCell runat="server">
                        <asp:Button ID="okButton" runat="server" Text="修改" OnClick="okButtonClick" />&nbsp;&nbsp;
                        <asp:Button ID="deleteButton" runat="server" Text="删除" OnClick="deleteButtonClick" />
                    </asp:TableCell>
                </asp:TableRow>
                <asp:TableFooterRow runat="server">
                </asp:TableFooterRow>
            </asp:Table>
        </div>
    </div>
这里是JS代码
// 图片显示
function show(id, imgUrl, title, info) {
    document.getElementById("pictureId").value = id;
    document.getElementById("img").src = imgUrl;
    document.getElementById("title").value = title;
    document.getElementById("info").value = info;
    document.getElementById("newArea").style.display = "block";
    document.getElementById("PictureDetail").style.display = "block";
}
