Question

How do I send a cross-domain POST request via JavaScript?

Notes - it shouldn\'t refresh the page, and I need to grab and parse the response afterwards.

I know this is an old question, but I wanted to share my approach. I use cURL as a proxy, very easy and consistent. Create a php page called submit.php, and add the following code:

Then, in your js (jQuery here):

$.ajax({
type: 'POST',
url: 'submit.php',
crossDomain: true,
data: '{"some":"json"}',
dataType: 'json',
success: function(responseData, textStatus, jqXHR) {
    var value = responseData.someKey;
},
error: function (responseData, textStatus, errorThrown) {
    alert('POST failed.');
}
});
