我做了我的代码来找到HTML控件“源”,我想检查“ Src ”属性是否有值,我试图添加“内部文本”但它返回NULL。
<asp:DataList ID="DL_Media" runat="server" onitemdatabound="DL_Media_ItemDataBound">
<ItemTemplate>
<video width="215" height="160" runat="server" id="vd" controls>
<source src='<%# Eval("Media_File")%>' type="video/ogg"
runat="server" id="source"></source>
</video>
</ItemTemplate>
</asp:DataList>
protected void DL_Media_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
HtmlGenericControl video = e.Item.FindControl("vd") as HtmlGenericControl;
HtmlGenericControl source = e.Item.FindControl("source") as HtmlGenericControl;
if (source != null)
{
string x = "~/";
string y = "";
if (source.InnerText == x)
{
video.InnerText.Replace(x, y);
DL_Media.DataBind();
}
}
}
