 Posted: Mon Aug 25, 2008 7:54 pm Post subject: Detect when a page is loaded (reliable, cross-browser) |
 |
|
I needed this feature and I've seen there was no solution which worked reliably in Firefox and Opera (I don't use IE, I assume there is some COM solution for it).
It uses user Javascript to monitor when the page is loaded and modifies the page title if it's loaded, so one can query it with wingetttitle.
For Firefox GreaseMonkey needs to be installed for the script to work, Opera has the necessary functionality built-in.
It's not a pure AutoHotkey solution, but at least it works reliably.
| Code: | // ==UserScript==
// @name loaded
// @namespace my
// @description indicate if a page is loded
// @include http://www.cnn.com
// ==/UserScript==
window.addEventListener(
'load',
function (e) {
document.title += " [loaded]";
}, false);
|
See also this topic for an other feature using the same technique.

Unfortunately there is no COM interface to the afore mentioned browsers thus no AHK COM solution to be had
Thank you keyboardfreak this has been many times asked for and is the best idea I have seen but it as you mentioned isnt an ahk solution but a Grease Monkey/Javascript Solution. Albeit a pretty darn good one
I think once Firefox exposes its internal methods and properties to other languages other than mozilla plug in based then the move from IE to mozilla in the corp world can finally begin. But not untill then
another interesting solution I found is

As far as COM IE and Gui Browsers go
http://www.autohotkey.com/forum/viewtopic.php?t=34972&highlight=
The above link is a complete COM IE Gui Browser tutorial
This is just an excerpt the first 2 snippets do not standalone but the 3rd one that I got from Sean does

another way to check if a page has loaded using javascript via com | Code: | pwin:=COM_Invoke(doc:=COM_Invoke(pwb,"Document"),"parentWindow")
if pwin is integer
loop
If rdy:=COM_Invoke(pwin, "execScript","var rdy=document.readyState","rdy") = "complete"
break |
of course always release objects not textyou wouldnt release rdy but you would release doc in the example above
a comletely independent way to check readystate requires tab if enabled to be the selected tab but doesnt require the window to be active

Simple yet effective, another why didn't I think of that  If there are any GM clones for IE window.attachEvent('onload',function (){document.title+=' [loaded]';}); would be a valid hook.

Not sure why, perhaps it's an anti-XSS rule. Firefox doesn't have this problem. Here's an example of the embedded script, which works.
