jquery - building a list and sending to an AJAX method -

i building list array pass via ajax using data parameter.

everything looks when write out list console, ajax method doesn't it.

for (i = 0; < carlist.length; i++) {      var cardata = { "data": { "carid": '"' + carlist[i] + '"', "passengercar": "true", "automatic":"true" } };     console.log(cardata); }  $.ajax({ datatype: "json", data: cardata  .... 

am doing improper?
