DOM of another window or URL

Copy linkTweet thisAlerts:
Nov 02.2005

Question: Why is the result of this:

[CODE]
 var main2 = ‘ ‘;
main2 = window.open(“http://www.google.com”, “main2”);
document.write(main2.location.href);
[/CODE]

this?:

[CODE]
 about:blank
[/CODE]

I would think it should be:

[CODE]
 http://www.google.com
[/CODE]

Furthermore, is there any simple way to grab the DOM by supplying a URL? I’m looking to turn the web into my database (with support for cookies) with Javascript or PHP but not with Perl, as described in this <a href=http://www.developer.com/lang/article.php/3495126>article</a>.

@KorNov 02.2005 — you have gave the same name to the variable and to the name of the window (which are different things)

var main2 = window.open("http://www.google.com", "[COLOR=Red]doesntmatter[/COLOR]");

document.write(main2.location.href);

@robinhoodeauthorNov 02.2005 — Ok.. yet this:

var whatever = window.open("http://www.google.com");

document.write(whatever.location.href);

or this:

var whatever = window.open("http://www.google.com");

document.write(whatever.location);

still returns:

about:blank

I'm trying to extract info on a given web page (one which has cookies), from the web browser. This is just a start in that direction.

@KorNov 02.2005 — well, yes. If the two pages are from different domains, you can not reach them via javascript. But you can use AJAX to grab information from another page, if different domain.

Success!
