合并到哪？this?

var a =document.getElementById("kiler2"), b =document.getElementById("kiler1");
alert(a.innerHTML+b.innerHTML);

[郭大侠_]

function test()
{
    var obj=document.getElementById("aa");
    var str=obj.innerText;
    alert(str);
    obj.innerHTML=str;
}

  <script>
      var a=document.getElementById("aa").getElementsByTagName("div");
      document.write(a[0].innerHTML+a[1].innerHTML);
</script>

调试过

[yuzi13631138780]

var aa=document.getElementById("aa");
      var a=document.getElementById("aa").getElementsByTagName("div");
      a[0].innerHTML+=a[1].innerHTML;
      aa.removeChild(a[1]);
