Network error in Jquery post

I am getting an error when doing a Jquery post (Error: A network error occurred.)

With Postman, it does work, here is the cURL: 

POST /site/restapi/postalcode HTTP/1.1
Host: localhost:8080
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 14d39deb-fc28-3171-d688-18deaca7cbbe

{
"postalCode" : "9041AK",
"houseNumber" : "1"
}

Unfortunately with my javascript it does not:

$('input[name="houseNumber"]').blur(function() {
        // Check if the street and city can be fetched
        $.ajax({
            type : "POST",
            contentType : "application/json",
            url : "localhost:8080/site/restapi/postalcode",
            data: { postalCode : "9713GC", houseNumber : "1" },
            dataType: "json",
            crossDomain: true,
            success: function(data) {
                console.log(data);
            }}).fail(function(data, status, error) {
                console.log("error!" + error);
        });

    });

Edit: I have installed the firefox add-on Tamper Data, this gives insight to all requests being sent. This has given some additional information: no request is really being sent at all. (Apart from the GET request on loading the page.)

What is going on? Why does it not work?

Your url in the request is wrong.

If you write "localhost:8080/site/restapi/postalcode", then localhost will - depending on the implementation of the url parser - referrer to protocol or the path will interpreted as relative path, but then localhost:8080 in both cases would not be interpreted as host.

You have to write one of the following:

  • "http://localhost:8080/site/restapi/postalcode"
  • "https://localhost:8080/site/restapi/postalcode"
  • "//localhost:8080/site/restapi/postalcode"
  • "/site/restapi/postalcode"

Which one depends on the url you initiate request from.
