 <td class="a"></b><a href="edit.php?id=$id">edit</a></td> 

how do i get the id using #contactForm

any idea’s

Sorry, I don’t quite understand your question.
Which id do you mean?

#contactForm is a fragment identifier.

You can select the link whose href this is like so (using jQuery):

$('a[href="#contactForm"]')

or (vanilla JavaScript):

var links = document.getElementsByTagName("a");
for(var i=0, len = links.length; i < len; i++){
  hash = links[i].href.split('#')[1]	
  if(hash === "contactForm"){
    //do something with links[i]
  }
}
