Href and onClick?

[Dave Mennenoh]

I have a Flash based video player that uses a javaScript function on the
page to modify variables within the Flash. This is so, external, jpg,
thumbnails can change the video without reloading the page. This works great
using:

<a href="javascrip t:changeVideo(' videoName.flv') "><img
src="thumbname. jpg"></a>

Now, my client wants to be able to track which videos are watched by calling
a cgi script she has in place. I've been trying all morning to come up with
something so I can call my current changeVideo() function, and also post a
variable to a cgi.

<a href="javascrip t:changeVideo(' videoName.flv') "
onClick="myTrac ker('videoName. flv');"><img src="thumbname. jpg"></a>

Then, within myTracker I am trying to submit a form with a hidden field...
it does work, except when I submit the form I redirect to the url I am
calling. I need to 'silently' post the form data.

function myTracker(vname ){
//set form value
document.hidden Video.vname.val ue=vname;
document.hidden Video.submit();
}

You could use a hidden frame to submit to the Cgi page so that the user
never sees it...

You have two choices:
- You can use AJAX
- You can use a Iframe

I would choose to use AJAX personally since it's so lightweight
Make sure you choose to post and not get.
Here is an example

There are more than that.
- You can use AJAX
- You can use a Iframe
3) Use a process a lot more reliable - set the .src property of an image
to the cgi script.

Title of that entry in the group FAQ?

4.34 How do I run a server side script?

Then you would choose the worst way of doing it.

With the FAQ answer using an image, you don't have to do either.

Irrelevant and useless to the OP's question.

Thanks for all the help! I ended up going with a hidden iframe which seems
to work. Are there any issues with that? I see Randy said setting the SRC
property of an image is more reliable. Wondering why.

And thank you for quoting what you are replying to next time.

Yes, hidden IFrame's have been used for years.
Are there any issues with that?
Not really. Most browsers support it enough that it isn't an issue.
I see Randy said setting the SRC property of an image is more reliable.
Wondering why.

Only because more browsers support image src setting than IFrame's. And
the history trail issue when it comes to Frames and IFrames. If you need
to transmit a lot of data then the hidden iframe is the way to go. If
the only thing you need to do is trigger a server side script, then
setting the .src property of a hidden image is simpler, doesn't mess
with the History trail, and is very very widely supported. It is, by
far, the best way to do it. And that reliability is precisely why the
FAQ entry on this issue uses that method.

Thanks, but I use OE's news reader.

And that reliability is precisely why the FAQ entry on this issue uses
that method.

If i have issues with the iframe I'll check that out.
