ajax async: false not honored for remote script loading

Description

$.ajax({

type: 'GET',

url: 'http://api.recaptcha.net/js/recaptcha_ajax.js',

dataType: 'script',

async: false,

success: function() { alert('a'); }

})

alert('b');

The alertt'(b') gets fired before alert('a') which should never happen. Looking into the source it seems that the 'async' option is never used when $a.ajax detects s.dataType === "script" && type === "GET" && remote. See line 5062 of jquery.js

resolution: → wontfix
status: new → closed

Remote scripts are not handled by XMLHTTPRequest, since XHR cannot be used for cross-domain access. Instead a 

script
tag is injected into the page.

I've closed this as wontfix, but it's really cantfix because of the technologies involved.

I've updated the documentation for $.ajax to clarify that 

async: false
cannot be used for cross-domain requests.
