javascript function in Linkbutton not firing in FireFox browser

[jegathambigai]

when i click the link button in Masterpage the window has to close. This function is working properly in IE but in fireFox or chrome or Safari
Other than IE in all browsers postback is happening.

my code :

<asp:LinkButt on ID="Logout" runat="server" OnClientClick=" closewindow();" >Logout</asp:LinkButton>


<script>
function closewindow()
{
window.close();
}
</script>

Please help me to solve this issue.

Thanks in advance

If you want to prevent the ASP.NET button from causing a postback, then have the Javascript function return false and set your on OnClientClick attribute as follows

<script type="text/javascript">
function closewindow()
{
window.close();
return false
}
</script>
