ContentType Accepts DataType

  • ContentType: When sending data to the server, use this content type. Default is application/x-www-form-urlencoded; charset=UTF-8, which is fine for most cases.
  • Accepts: The content type sent in the request header that tells the server what kind of response it will accept in return. Depends on DataType.
  • DataType: The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response. Can be text, xml, html, script, json, jsonp.
