Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

Sending JSON to your web server using jQuery


Sending JSON to your server using jQuery is easy. Just get the data in the JSON format and specify it using the ajax method argument's data field.

How to do it...

Let's look at doAjax again, this time modified to send our request JSON:

function doAjax() {
  $('#debug').html("loaded... executing.");
 
  var request = { 
    call: "kf6gpe-7"
  };

  $.ajax({
    type: "POST",
    url: "/",
    data: JSON.stringify(request),
    dataType:"json"
  });
}

</script>
</body>
</html>

How it works…

The magic line in the previous listing is highlighted; it's the following line in the arguments passed to the ajax method:

    data: JSON.stringify(request),

Of course, we use JSON.stringify to encode the JavaScript object as JSON before assigning it to the data field.
