As you have correctly stated getElementsByTagName does not return an array, hence UBound() will not work on it. Treat it as a collection.

正如您正确地声明了getElementsByTagName不返回数组，因此UBound()不会对它起作用。把它当作收藏品。

For-Eaching through it should work:

通过它进行操作应该是有效的:

 Set NodeList = document.getElementById("itemsTable").getElementsByTagName("TR") 
 For Each Elem In NodeList
  ' stuff 
  MsgBox Elem.innerHTML
 Next

If you have IE8+, you can use the "item" method. So it'd be:

如果你有IE8+，你可以使用“item”方法。所以它会:

Dim elem: Set elem = document.getElementById("itemsTable").getElementsByTagName("TR").item(1);

elems isn't an array in Javascript either, it is a NodeList, it just happens to share some properties with a Javascript Array object.

elems也不是Javascript中的数组，它是NodeList，它只是碰巧与Javascript数组对象共享一些属性。

I don't know VB, but I assume you could do:

我不知道VB，但我想你可以:

for j = 0 to elems.length - 1      
   ' stuff 
next
