Pour IE on trouve ce script plus simple partout :
<SCRIPT LANGUAGE=JavaScript>
var RealMode=0;
var RealPlayer5=0;
var RealPlayer4=0;
var RealPlayerG2=0;
if (navigator.userAgent.indexOf("MSIE")<0 )
{
numPlugins = navigator.plugins.length;
for (i = 0; i < numPlugins; i++)
{
plugin = navigator.plugins[i];
if (plugin.name.substring(0,10)=="RealPlayer")
{
RealMode=1;
}
}
}
document.write('<SCRIPT LANGUAGE=VBScript\> \n');
document.write('on error resume next \n');
document.write('RealPlayerG2 = (NOT IsNull(CreateObject("rmocx.RealPlayer G2 Control")))\n');
document.write('RealPlayer5 = (NOT IsNull(CreateObject("RealPlayer.RealPlayer(tm) ActiveX Control (32-bit)")))\n');
document.write('RealPlayer4 = (NOT IsNull(CreateObject("RealVideo.RealVideo(tm) ActiveX Control (32-bit)")))\n');
document.write('</SCRIPT\> \n');
if (RealMode || RealPlayerG2 || RealPlayer5 || RealPlayer4)
{
alert("You Have RealPlayer! CLICK OK, then CLOSE THE WINDOW and listen to our audio clips!");
}
else
{
alert("You DO NOT have RealPlayer. You will need to download and install the FREE RealPlayer to listen to our audio clips. CLICK OK, then DOWNLOAD the FREE RealPlayer.");
}
</SCRIPT>
Et pour Netscape, tu as cet exemple très complet "Browser and Real Player Support" (http://www.alllearn.org/help/browser.html)
