Question

I have some Google Plus One javascript in my .ASCX file:

<script type="text/javascript">
    (function () {
        var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
        po.src = 'https://apis.google.com/js/plusone.js';
        var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
    })();
</script>

I need to hide this bit of code from IE7 and IE8 browsers.

What is the proper way to do this?

Answer 1

Markup Method

<%  If Not (Page.Request.Browser.Browser.StartsWith("IE", StringComparison.OrdinalIgnoreCase) AndAlso Page.Request.Browser.MajorVersion < 9) Then%>
This is either Not IE, or IE 9 or greater<br />
<% end if %>

Code-Behind Method

Just Put the Script Inside PlaceHolder & Set Its visibility to true/false. Use to following function to detect browser in asp.net.

public static bool IsIE(Page page)
{
  if (page != null && page.Request != null && page.Request.Browser != null)
  {
    return page.Request.Browser.Browser.StartsWith("IE", StringComparison.OrdinalIgnoreCase) && (page.Request.Browser.MajorVersion == 7 || page.Request.Browser.MajorVersion == 8);
  }

  return false;
}
