我在页面上有一些链接,例如:
< a id="Digg" runat="server">< img alt="Digg" id="imgDigg" runat="server" src="~/resources/images/icons/social/digg_32.png" border="0" />< /a>
我有一个可以“打开”它们的数据库表,在我的代码后面我有以下内容:
string[] SocialMedia = new string[] { "Twitter", "Facebook", "LinkedIn", "Digg", "Email", "Print" };
private void CheckForSocialMedia()
{
int i = 0;
for (i = 0; i < SocialMedia.Length; i++)
{
bool AddSocialMedia = (bool)AllowSocialMedia(SocialMedia[i]);
if (AddSocialMedia == false)
{
// Hide the link: Digg.Visible = false;
}
}
}
protected bool AllowSocialMedia(string sSocialMedia)
{
SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["dbConn"].ConnectionString);
SqlCommand myCommand = myConnection.CreateCommand();
myCommand.CommandText = " select Settings.AllowsocialMedia " +
" from ArticleSocialMediaSettings Settings " +
" inner join SocialMedia on Settings.SocialMediaId = SocialMedia.id " +
" where SocialMedia.NetworkName = '" + sSocialMedia + "'" +
" and Settings.RetailerId = '1234'";
myConnection.Open();
try
{
SqlDataReader myReader = myCommand.ExecuteReader();
if (myReader.Read())
{
return (bool)myReader["AllowsocialMedia"];
}
}
catch (Exception ex)
{
throw ex;
}
return true;
}
如果函数返回false,我该如何隐藏链接?或者有更好的方法吗?

看起来这是检查数据库的正确方法。要隐藏您可以使用的链接:
document.getElementById("Digg").style.display = "none";

使用datalist重新设计
