Find the first occurance of an html tag that is visible

Recommended Posts

Spiff59

I'm wanting to grab the text from within a particular classame inside a particular HTML tag.

The _IE* functions work fine for that, but they return a collection of all matches. I'm only interested in the contents of the first match in the portion of the page currently being displayed. If my webpage is, for instance, three screens tall, and the target tag/classname occurs a couple times on each screen, is there a way to know which of the matching items are presently visible on the page?

Or, in a single sentence:

How does one determine which portion of a webpage's HTML is currently being displayed on screen?

Thank you.

To the first part of your question, you can iterate through the collection and get the matching item.

As for the second part - thats a Dale question. If you haven't already, have a look at debug bar as that can provide good clues.


Post your code because code says more then your words can. SciTe Debug mode - it's magic: #AutoIt3Wrapper_run_debug_mode=Y.

Read the help file a little closer. When you get collections with _IE* function, you can provide a 0-based index to specify which instance you want. The default is -1, which returns a collection of all instances.

I don't think there is an "OnScreen" property for an element, but you can get the browser window position with WinGetPos(), and get element position with _IEPropertyGet() using "screenX" and "screenY" properties. Then do the math.

:D

I think I'm out of luck. The occurance of the matching tag I want would be whatever one happens to be the first visible on the current screen. I have no way of knowing which occurance that may be.

Edit: I figured it out. Shell.Application.Windows().document.documentelement.scrolltop
