how to fetch innerHTML / Text of another page

[zeedoo]

Hi,

When i open an external website using window.open, e.g. from www.domain.com i open www.google.com via window.open, then when trying to fetch its innerHTML from domain.com window, I get permission denied. How can i fetch its text/html from the parent window? Please help I really need this one ...

In theory you should be able to do it like so AS LONG as you assign the open to a variale first:


var NewWin = window.open("http://www.google.com");
NewWin. {Your Reference here};



Hope that helps :)

What you are doing here is violating the same origin policy (http://www.mozilla.org/projects/security/components/same-origin.html). In other words, you can only "talk" to other pages on your domain. If you must obtain data from another domain look into using an XMLHttpRequest object or perhaps better, a server-side solution.

thanks for your quick replies, could you please give me more information / code on how do i fetch the content using Javascript and XMLHttpRequest ... Thanks ...

No problem. See: <http://www.codingforums.com/showthread.php?t=30449>.

the thing i want to comment here is, i want the target page to be loaded in the window and then the text to be fetched for manipulation ... will XMLHttpRequest help in that?

In fact, if you want to get this working entirely cross-browser you'll have to use server-side. Mozilla won't let you access other domains in this context (of which I would suspect). However, IE on the other hand does (living up to its insecure reputation). In any case, this method returns to current source code of the page/file you request. You will not be able to execute JavaScript on that page; you'll just have access to the markup.

well can i with this method, display the target site in its windows and also search its code from the parent window ? If so please please give some lines of code which will achieve this ...
