this to call each of the top menu

var arrayTop=document.getElementById("topmenu").getElementsByTagName("a");
for (i=0;i<arrayTop.length;i++){
  document.getElementById(arrayTop[i].id).addEventListener("click",topMenu,false);
}

the HTML

<div id="topmenu">
  <a id="help" href=#><span>Help</span></a>
  <a id="frum" href=#><span>Forum</span></a>
  <a id="home" href=#><span>Home</span></a>
</div>

but,how to apply addEventListener() when the id isn't specified? since some of the elements will have the same id. so i'll change the id attribute to be

<div id="topmenu">
  <a mnuid="help" href=#><span>Help</span></a>
  <a mnuid="frum" href=#><span>Forum</span></a>
  <a mnuid="home" href=#><span>Home</span></a>
</div>

  • 1 Conceptually, you should not assign the same ID to more than one elements. Also, the attribute "mnuid" is not valid. Why don't you change that "mnuid" to "id" ? – doc_id Commented Jan 24, 2011 at 3:28

Reset to default 8

You don't need the id. You already have the elements from the call to getElementsByTagName.

var arrayTop = document.getElementById("topmenu").getElementsByTagName("a");
for (var i = 0; i < arrayTop.length; i++)
{
    arrayTop[i].addEventListener("click",topMenu,false);
}
