AJAX request using jQuery does not work

Question

So I am new to jQuery and I\'m trying to set up an html page that has tabs. Each tab should show a different html page as follows:

   <         


        
                      

              相关标签:
       
      

Answer 1

In your case, it does not work because you're trying to access a file from user computer. It poses security risks because if javascript is able to access local files, javascript is able to steal files from client machine.

Even when I reference http://www.facebook.com in the url it doesn't work

The reason for this is: AJAX requests are subject to the same-origin policy. Facebook is on another domain, that's why it does not work.

One more thing to keep in mind, some browsers think absolute URLs are cross-domain requests even if it's in the same domain, only relative Urls work, so avoid using absolute Urls.

To fix your issues, try deploying on a server and use relative URLs instead of absolute URLs.
