Re: Error "Access-Control-Allow-Origin header not found"

It is better to use http instead of https.  Because https is a secure protocol to consume service from database.

Please find below codes to solve your issue, I hope this will helpful to you.

$.ajax({

  url:'https://,
  data: myData,
  type:'GET',
  crossDomain:true,
  dataType:'jsonp',
  success:function(){ alert("Success");},
  error:function(){ alert('Failed!');},
  beforeSend: setHeader
});
