Question

I am developing an extension for Mozilla Firefox. A main function is to get the URL that the user is visiting and process it later. I tried the following Javascript code:

window.onload = function(){
  alert(document.referrer);
}

That didnt work so I tried to inject an onclick event to every link using this:

window.onload = function(){ 
    var links = document.links;
    for(var i=0;i<links.length;++i){  
        links[i].onclick = show_href();
    }
}

function show_href(){
    alert(this.href);    
}

But that also doesnt work. Any other approach?

Answer 1

Try this:

<a href="#xxx">linktextx</a>
<a href="#yyy">linktexty</a>
<a href="#zzz">linktextz</a>
<script>
    window.onload = function() {
    var links = document.links;
    for(var i=0;i<links.length;i++){
        links[i].onclick = function(){alert(this.href)};
      }
    }
</script>
