Change link destination based on whether user has mac or PC

问题

Is it possible to change the destination of a link based on whether the user has a mac or a PC using javascript?

To give an example: The Apple website allows download of Quicktime but it "knows" whether you are using a mac or a pc and directs you to the relevant page.

Background/Reason for doing this: I have built a website for someone and they have a number of audio and video files on there. Ideally they want it so that if the user is on a mac it will download a quicktime version of the file but if they are on a PC it will download a Windows Media Player file.

Cheers

回答1:

You can check the UserAgent header to tell Mac and PC browsers apart.

回答2:

Yes. It's not foolproof, but can be done. Here's a sample of Javascript detecting your OS. You could simply opt to display a different div or something similar depending on the result.

Here is an example

<html>
<head>
<script type="text/javascript">
function yourOS() {
var ua = navigator.userAgent.toLowerCase();
if (ua.indexOf("win") != -1) {
    return "Windows";
} else if (ua.indexOf("mac") != -1) {
    return "Macintosh";
} else if (ua.indexOf("linux") != -1) {
    return "Linux";
} else if (ua.indexOf("x11") != -1) {
    return "Unix";
} else {
    return "Computers";
}
}
</script>
