Two days ago, I came across a problem. After building a restful web service for my app. I happily tried to access the data from the web service using phone. I sent request for data from server using following code:

$.ajax({ type: ‘GET‘, dataType: ‘json‘, async :false, error : function
(xhr, ajaxOptions, thrownError) { alert(xhr.readyState); alert(xhr.status); alert(thrownError); }, success: function
(data) { alert(data); }});} |
I used Intel XDK environment. emulator can return data. But when I test with real phone(both iphone and android) , xhr.status returned value 0. I started to search why this happened. Finally, I was aware of this cross domain request problem. Then start to search ‘phone gap cross domain request‘. Overall, they give two solutions:
I tried both, but none of them work.
I started feeling bad and disappointed. I went through a hard time :( , But this time, I didn‘t give up. Kept searching, kept believing that every problem in engineering must get a corresponding solution for it. Answer is here:http://software.intel.com/en-us/html5/articles/how-to-access-JSON-data-in-HTML5-apps.
Adding following two tags in our file.
<script src="intelxdk.js"></script>
<script src="xhr.js"></script>
intelxdk.js and xhr.js actual files are not required,it will be included automatically in Intel XDK tools, just the script tags should be included.
Then I use the statement suggested from this site:
