To use the QTObject embed, you simply create a new QTObject, add the parameters you want, and then write it to the page. The script will check to see whether the QuickTime plugin is available and write the embed code to the page or the alternate content if the user doesn’t have the required plugin. Here is an example of what a simple movie embed would look like (I used a fun little video I found floating around the Internet as a sample movie, but it can be any .jpg, .gif, .png, or even another .mov file.): (View Example)
var myQTObject = new QTObject("bushuncensored.mov", "bushfinger", "320", "255");
In this example the ‘
myQTObject.addParam()‘ isn’t needed, but it’s a nice addition that will keep the movie from starting before the user figures out what they are looking at.
The parameters from left to right are the path to the mov file, the ID of the mov file, the width, and then the height of the file. If you are showing the QuickTime controls, you need to add 15 pixels or so to the height of the movie or the controls will be pushed down and the user won’t be able to see them.
var myQTObject = new QTObject("bushplaceholder.jpg", "bushfinger", "320", "255");
This uses a few extra parameters that allow you to use a placeholder image that will load in the place of your movie until the user clicks on it. Your movie would then load in the place of the image and start when it has loaded enough to start playing. You simply replace the mov source from the first example with your placeholder image (you remembered to add 15 pixels to the height of the image to account for the QuickTime controls, right?) and then an extra few parameters to tell the QuickTime embed where to find the real movie, the target QuickTime object, and finally telling it to hide the controls before the real movie loads.
There is also the option of redirecting the user to another page if there is no QuickTime plugin found by using this code:
myQTObject.redirect = "upgradepage.html";, and there is a built in bypass of the detect script by including
Also, be sure you use this in combination with
object tags, it will validate as XHTML 1.0 (strict or transitional). Please note that it will not work with pages sent as
application/xhtml+xml since it uses
document.write(). Another note: I’m not checking for the version of the QuickTime plugin installed, and I couldn’t find any older QuickTime players for testing, so I’m not sure how this will treat users who are using QuickTime 4 to view content that requires QuickTime 6. I seem to remember QuickTime having an auto-update feature or some built in notification if you need to upgrade, so I’m not too worried about it, but if anyone has some experience in this area, I’d love to hear how this embed method behaves under those circumstances.
I’ve tested this on IE 6, 5.0, 5.5 on PC, Firefox on Mac and PC, and Opera and Safari on Mac. It has worked great every time, but everyone knows there can always be little bugs that pop up, so if anyone finds something wrong with the code, let me know.
UPDATE (02-11-2005): Just fixed a few bugs – one that was giving problems if the user didin’t have QuickTime installed on Internet Explorer for PC, and adjusted the default Alternate text.
UPDATE (02-16-2005): Not sure how something like this slipped past, but Thiago found a little bug in the VB Script that was giving some problems in IE on a PC. The files have all been updated.
