document.getElementsByTagName在vbscript中工作吗？

问题描述

  
  因此 UBound（）不起作用。将它作为一个集合处理。
 
 
 
通过它进行Eaching应该可以工作： 
 
 
  Set NodeList = document.getElementById（itemsTable）。getElementsByTagName（TR）
 For Each Elem In NodeList 
'stuff 
 MsgBox Elem.innerHTML 
 Next 
  
 
Well, it works, it just doesn't produce anything worthwhile: 
elems = document.getElementById("itemsTable").getElementsByTagName("TR") 
for j = 0 to ubound(elems) - 1      
   ' stuff 
next
Well, that won't work, apparently elems is an object, not an array like you'd get in that fancy javascript. I'm stuck with vbscript though. 
So what do I do to iterate all the rows in a table in vbscript? 
Edit: Yes, it's vbscript and it sucks. I don't have a choice here, so don't say "Use jQuery!!". 
 解决方案 
As you have correctly stated getElementsByTagName does not return an array, hence UBound() will not work on it. Treat it as a collection.
For-Eaching through it should work:
 Set NodeList = document.getElementById("itemsTable").getElementsByTagName("TR") 
 For Each Elem In NodeList
  ' stuff 
  MsgBox Elem.innerHTML
 Next
