Post data to JsonP
ajax, javascript, jquery, json, jsonp
Solution
It is not possible to do an asynchronous `POST` to a service on another domain, due to the (quite sensible) limitation of the same origin policy. JSON-P only works because you're allowed to insert `<script>` tags into the DOM, and they can point anywhere.
You can, of course, make a page on another domain the action of a regular form POST.
Edit: There are some interesting hacks out there if you're willing to go to a lot of effort inserting hidden `<iframe>`s and mucking about with their properties.
Problem
Is it possible to post data to JsonP? Or does all data have to be passed in the querystring as a GET request? I have alot of data that I need to send to the service, cross domain, and it is too large to send via the querystring What are the options for getting around this?
