Retrieving JSON data

Here is a URL that returns JSON data: Link. I am attempting to access this data with the following script:

$.ajax({ 
type: 'GET', 
url: 'http://www.spritpreisrechner.at/espritmap-app/GasStationServlet?data=%5B%22Stgilgen%22%2C%22DIE%22%2C13.3597716%2C47.7689327%2C13.3597716%2C47.7689327%5D', 
dataType: 'jsonp',
success: function (data) { 
    $( "body" )
        .append( "Kredit: " + data.kredit ) 
        .append( "postalCode: " + data.postalCode ); 
} });

Unfortunately, this script does not seem to be working. Any suggestions on how to make it work?

Answer №1

To ensure successful access to another domain, make sure to set the "crossDomain" flag to true in your jQuery code. This may seem redundant, especially when using jsonp, but it is essential.

http://api.jquery.com/jQuery.ajax/

Answer №2

If you find yourself unable to access a certain domain, like Spritepreisrechner.at, the best course of action would be to reach out to them and request to have your domain added to their Access-Control-Allow-Origin. Without owning or having authorization for that domain, accessing it may not be possible.

An alternative approach is to utilize the server side of your application to handle the request and generate the response. This can be done by creating a proxy page that forwards the request. For instance, if your server side is running on PHP, you could include a basic script like this:

<?php echo file_get_contents("http://www.spritpreisrechner.at/espritmap-app/GasStationServlet?data=%5B%22Stgilgen%22%2C%22DIE%22%2C13.3597716%2C47.7689327%2C13.3597716%2C47.7689327%5D");

Keep in mind that using jsonp won't work in this scenario, as the JSON data lacks a callback function necessary for access.

Answer №3

Received the information

$(document).ready(function () {
$.ajax({
    type: 'GET',
    url: 'http://jsonp.guffa.com/Proxy.ashx?url=www.spritpreisrechner.at/espritmap-app/GasStationServlet?data=%5B"Stgilgen"%2C"DIE"%2C13.3597716%2C47.7689327%2C13.3597716%2C47.7689327%5D',
    dataType: 'jsonp',
    success: function (data) {
        console.log(data);
    }
});

});

Thank you to everyone who helped!
