Advanced JavaScript for Reputation

[taekwondokid42]

I'm working on something involving hosting advertisements, and I need several things:

1. Something that tells the server when an ad has been on screen for 2 or more seconds (the exact time is not necessary)

2. Something to tell the server when an ad gets clicked on

3. A picture-link that serves as the advertisement.

You are gonna want to use AJAX if you want that done quickly and quietly.
If I had time I would make a demo script for you but as of now I'm really busy.

ok thanks. Does AJAX run on all servers?

I will need a way for the ad to work on any server, even a poorly equipped one. One thing I could do is link the JS to the AJAX script on my server, but I'm not sure what the most efficient route would be.

AJAX is client side, more or less. It's basically a browser bar, and then you get the response. So if you request a page on your site, such as, test.html, your response text would contain the contents of the file.

AJAX consists of a server-side (usually php) and client-side (usually javascript) part. So you only will need a server with php and a user with javascript enabled.

thats exactly what I wanted to hear. Thank you. I'll start off with AJAX then.

if someone could give me a script though, I'd probably pay credits.

(marshian, I tried to give you rep, but it says spread some around first *roll*)



More things: I've been looking at google ads and wondering how they do it 12 lines of code. Does anyone have a deeper explaination?

 

[marshian]

You can do it in one line of code! Just put all code on one line...
(I've heard that before, I'm just too popular ;p)

:slap:
Edit:
I got the ajax end working, but now I need the JS that will activate stuff onclick and after 2 seconds of being on screen. Can anybody give me a tag or function that might do that?

 

[marshian]

Javascript execution after a fixed period is done using setTimeout(). eg:

document.onload = setTimeout(dostuff, 5000);
function dostuff() {
  //Gets executed 5 seconds after page load
}

This example should work if i'm not mistaking

Onclick is just adding the onclick field to a html element. Many of them support this event. eg:

<img src="http://forums.x10hosting.com/programming-help/image.png" alt="" onclick="javascript:dostuff()" />
<script language="javascript">
function dostuff() {
  //Gets executed when the user clicks the image.
}
</script>
