jQuery: I get OPTIONS request instead of GET

Question

I am using simple jQuery

$.get( .... );

Here instead of getting GET response I get OPTIONS.( checked in firebug Net)

Same code is working fine in Safari. Looks like some problem with Firefox.

Any workaround / solutions to fix this problem..

Thanks

Answer 1

Hi

I'm getign the same but with $.load(); Did you find solution ?

Answer 2

This is likely due to restrictions on Javascript doing cross-domain XMLHttpRequests. This is generally not allowed for security reasons. See the question referenced above, or a similar question I asked.

To solve this problem:

• Write a sever side component (using PHP or whatever) that will retrieve the remote resource on behalf of your AJAX request, or
• Do a JSONP call: see http://www.insideria.com/2009/03/what-in-the-heck-is-jsonp-and.html (or hunt around StackOverflow for JSONP) :)

Hope that helps!

Answer 3

The OPTION request what you see is the preflighted request, you can read about that here:

• https://developer.mozilla.org/En/HTTP_access_control
• http://www.w3.org/TR/cors/
• http://msdn.microsoft.com/en-us/library/cc288060(VS.85).aspx

It's because you're requesting a cross-domain XMLHttpRequest so the browser has to check whether your request is allowed on the remote server or not.

There are two solutions to solve the problem (as mentioned above):

• implement the response for the OPTION request with the corresponding Access-Control-* headers
• use JSONP instead of simple JSON

KARASZI István's answer is accurate. I've also stumbled upon the same issue, here's my insights on it; http://engin.bzzzt.biz/2010/01/25/cross-domain-xhr-access-control-preflight/

Answer 5

I had the same issue, because in my head i had

<base href="http://local.develepment.url" />

which i changed to

<base href="http://&lt;?php echo $_SERVER['HTTP_HOST']?>/" />
