Please see the code below.
if(ieVersion == "6.0")
{
window.opener=null;
window.close();
}
else if(ieVersion == "7.0")
{
window.open('', '_parent', '');
window.close();
}
It should be noted here that if you want to close the entire browser under IE7, window.open( '','_parent', ''); The second parameter in should be changed to '_self', '_parent' closes a single tab page.
