How to annoy a little bit less to our visitors (And still show ads)

How to annoy a little bit less to our visitors (And still show ads); well; making a little option to close; for example if you have a big adsense ad and you want the users to be able to erase the ad, here is the code:

<script   type="text/javascript">
function lclean()

{
   document.getElementById("clean").innerHTML="";
   document.getElementById("closebtn").innerHTML="";
}

</script>

<a  onClick="clean()" id="closebtn">[CLOSE] </a>
<div id="[B]clean[/B]"></div>

Code (markup):

Inside the DIV with ID Clean must be the content to be erased (the ad)

You can look my example at www.jraw.net (click on any blog entry)
Easy trick!

 

Thanks but where will I put the ad code?

 

Not all networks allow ads to be put in floating banners i guess

 

This code does work on mine... where will i put the ad code?

 

Example:

Current Ad code

[COLOR="DarkOrange"]<div>google_ad_client = "pub-9286332797346108"; 
/* 728x90, created 12/24/09 */ 
google_ad_slot = "4731117427";
google_ad_width = 728; 
google_ad_height = 90; 
r</div>[/COLOR]

Code (markup):

Modificated version with close button

<script   type="text/javascript">
function clean()

{
   document.getElementById("clean").innerHTML="";
   document.getElementById("closebtn").innerHTML="";
}

</script>

<a  onClick="clean()" id="closebtn">[CLOSE] </a>
<div id="clean">

[COLOR="DarkOrange"]<div>google_ad_client = "pub-9286332797346108"; 
/* 728x90, created 12/24/09 */ 
google_ad_slot = "4731117427";
google_ad_width = 728; 
google_ad_height = 90; 
r</div>[/COLOR]

</div>

Code (markup):

Simple

 

Good trick.. Is it legal?? Will google allow it??

 

You are just giving the option to hide it, what could be ilegal about that?

 

I tried this but it doesnt work on adbrite... The close button is not clickable

 

Mmmm... it works for me in adsense; and also with an affiliaton script from jlist.com
