document.getElementsByTagName在vbscript中工作吗？ [英] does document.getElementsByTagName work in vbscript?

问题描述

  elems = document.getElementById（itemsTable ）.getElementsByTagName（TR）
 for j = 0 to ubound（elems） -  1 
'stuff 
 next 
  

好吧，那不会起作用，显然elems是一个对象，而不是像你在那个 javascript中看到的数组。尽管如此，我仍然坚持使用VBScript。

那么我该如何迭代vbscript中的表中的所有行呢？

编辑：是的，它是vbscript，它很糟糕。我在这里没有选择，所以不要说使用jQuery !!。

解决方案

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
