OnFocus = "this.blur ();" problem

Question

// I am trying to apply an "onfocus="this.blur();"" so as to remove the dotted border lines around pics that are being clicked-on
  // the effect should be applied to all thumb-nail links/a-tags within a div..

  // sudo code (where I am):
  $(".box a").focus(  // so as to effect only a tags within divs of class=box |  mousedown vs. onfocus vs. *** ?? | javascript/jquery... ???
  function () 
  {
      var num = $(this).attr('id').replace('link_no', ''); 
      alert("Link no. " + num + " was clicked on, but I would like an  onfocus=\"this.blur();\" effect to work here instead of the alert...");

      // sudo bits of code that I'm after:
      // $('#link_no' + num).blur();
      // $(this).blur();
      // $(this).onfocus = function () { this.blur(); };


  }
  );

 // the below works for me in firefox and ie also, but I would like it to effect only a tags within my div with class="box"
   function blurAnchors2() 
             {
              if (document.getElementsByTagName) {
                   var a = document.getElementsByTagName("a"); 
                    for (var i = 0; i < a.length; i++) {
                          a[i].onfocus = function () { this.blur(); };
              }
                }
          }

Answer 1

Thanks guys, I went for css ( a:focus):

img, a:focus{
    outline: none;
}

It seems to work correctly (tabbing still works, and the borders are gone when clicked) for me ... in both ie and firefox. Now you have to modify some other links to use it ...

Thanks again.

It is not recommended to wash. If everything you are looking for hides the focus lines, use instead:

a[i].onfocus = function () { this.hideFocus = true; };

This will work for all versions of IE. For other browsers (including IE8 in standard mode), you can set the outlineCSS style to hide the focus paths:

a {
    outline: none;
}

I would suggest using only CSS to remove the border.

img, a:active{
    outline: none;
}

Or is there a specific reason JS needs to be used?
