jQuery Question

$.post() doesn't send data as json but as x-www-form-urlencoded instead

This one is really weird. I've multiple

$.post()
in the code but there is one dunno why sends the json parameters as
x-www-form-urlencoded
instead and therefore doesn't work.

Here's the code:

$.post("/Route/SaveTransportProperties", { properties: JSON.stringify(propArray), currTravelBox: JSON.stringify(travelBoxObj), accessToken: getAccessToken()}, function(data)
{
//DO STUFF
});


The XHR looks like this in Firefox:

Any ideas why is this happening? I also enforced the type as 'json' but doesn't work either.

Answer

If you want to send the data as json then use the $.ajax function

You can specify type post and dataType json.

$.ajax({
  url: "mydomain.com/url",
  type: "POST",
  dataType: "xml/html/script/json", // expected format for response
  contentType: "application/json", // send as JSON
  data: $.param( $("Element or Expression") ),

  complete: function() {
    //called when complete
  },

  success: function() {
    //called when successful
 },

  error: function() {
    //called when there is an error
  },
});

Taken from ajax documentation

contentTypeString
Default: 'application/x-www-form-urlencoded; charset=UTF-8'
