Question

I have a web application. On the client side I basically need to get the values of some fields and turn them into JSON and then send them to the server in an AJAX kind of way.(asynchronous)

How would you do that? I also am using jQuery

Answer 1

If you want to create JSON (also called stringifying) on the client side, you can use the stringifier from json.org. More details about its use here.

You would then use your normal jQuery.ajax(...) like so:

function sendJSON(dataToStringify) {
   var stringifiedData = JSON.stringify(dataToStringify);

   jQuery.ajax({
      url: 'http://some.url.here',
      data: {stringified: stringifiedData},
      success: function(data) {
         //code to handle successful AJAX post
      },
      error(XMLHttpRequest, textStatus, errorThrown) {
         //code to handle errors
      }
   });
}
