Question

我希望获得服务器端div的'display'css值！
以下代码不起作用：

    if (div.Style["display"] == "none")
    {
        div.Style.Add("display", "table-row");
    }

我怎样才能在c＃中获得该值？

提前致谢

Answer 1

你不能这样做，但我猜你正在应用一些逻辑来做一些事情，如果你的div可见或不显示（dispay：none或none）。如果是这样的话，为什么不使用html输入元素并根据需要切换其值？

Answer 3

您无法在服务器端执行您要执行的操作。 Style属性仅适用于内联样式。考虑客户端JavaScript。

<div id="div" runat="server" style="display: none;">Foo</div>

Answer 4

~~div.Attributes [“style”]。添加（“display”，“table-row”）~~

使用此：

if (div.Attributes["style"].ToString().Contains("display:none;")) 
{ div.Attributes.Add("style", "display:table-row"); }

或尝试

div.Attributes["CLASS"].ToString().Contains("CLASS_NAME")

如何在代码后面读取（获取）服务器端div的css样式值（未设置）？
