    onunload action

    Hi,
    I have an onunload event in the body tag. When it is activated I want to
    know if a <a></a> href was clicked and which one. Is there some document
    property or any other object available for such a thing?

    No, thanks, I don't want to use the onclick or any other event on the <a>
    tag.

    Thanks

    Frank

      document.body.o nunload=functio n(){
      if( document.active Element &&
      document.active Element.tagName &&
      document.active Element.tagName .toLowerCase()= ='a' )
      alert(document. activeElement.h ref);
      }

      This will not work in every browser, and it will work incorrectly if user
      focuses an <a> then changes his mind and types a new url in the address bar,
      since the link will be the active element, but not the reason for the
      unload.

      Perhaps a better approach is to put an onclick handler on every <a> after
      all.
      This isn't too difficult however, with a loop through all links onload:
      for(var
      i=0;i<document. links.length;i+ +)document.link s[i].onclick=somefu nction;

          Play with this:

          var clicked; // this is a global variable

          function init() { // call this onload
          var links = document.getEle mentsByTagName( 'a');
          links[0].prototype.oncl ick = function() { clicked = this.href };
          }

          Something like that; the idea is that each click on a link will write it's
          href into a global variable -- on unload just check the global's value.

              Thanks both, you sent me in the right direction. For the moment I decided
              on
              <SCRIPT FOR="hrefid" EVENT="onclick" >
              alert('yep');
              </script>
              This way the <a> does not contain javascript and it serves my purpose.

                  <head>
                  ...
                  <meta http-equiv="Content-Script-Type" content="text/javascript">
                  ...
                  </head>

                  <body>

                  <a href="whatever. htm" onclick="alert( 'yep'); return false" ...>...</a>

                  serves it even better (and without an ID) than your proprietary IE nonsense.
