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?
There are a number of ways to do this, if you are already including jQuery, you could use its browser sniffing functions. The other option is you could use IE conditional comments: http://msdn.microsoft.com/en-us/library/ms537512%28v=vs.85%29.aspx.
<% 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 %>
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;
}
<!--[if !(IE 7)&!(IE 8)]>
You are not using IE7 or IE8
<![endif]-->
