Lets say for example i have an google search results page opened in a window or a tab in firefox.Is there a way i can retrieve the html code of that tab or window using javascript? I suppose that the webpage html is saved temporarily somewhere in computer memory. Can i load the webpage using memory saved address? Is there a way for javascript to read html files saved in the same folder as the original?For example i have saved the webpage in a folder on my computer.If i create an html file inside the same folder does javascript consider the saved webpage as the same domain?

What you would need is some server-side code that will retrieve the other site's code for you to manipulate. JavaScript can't do it for you (unless the user explicitly and foolishly opens up that security hole for you).Blazemonger– Blazemonger2011-12-20 17:27:39 +00:00Commented Dec 20, 2011 at 17:27

The OTHER site has to ask the user to grant permission. Do you control both sites? If not, you're out of luck without using server-side code.Blazemonger– Blazemonger2011-12-20 17:33:52 +00:00Commented Dec 20, 2011 at 17:33

No. JavaScript lives and dies within the browser. It does not have access to the file-system.Bhesh Gurung– Bhesh Gurung2011-12-20 17:39:45 +00:00Commented Dec 20, 2011 at 17:39

No, you most certainly can't do that unless you control both pages. This would be a huge security hole.

There is a custom search API which may help if you specifically want to do Google searches. It appears to have a JSONP implementation which should let you make a cross-domain request, but I haven't tried it out so I'm not sure how well it works.
