jquery $.ajax problem

jquery $.ajax problem

i have html form like this.

<form action="xyxz/reguser.asp" method="post" enctype="multipart/form-data">
  First name: <input type="text" name="fname"><br>
  Last name: <input type="text" name="lname"><br>
  <input type="submit" value="Submit">
</form>

I like to use Action , method and enctype in $.ajax method instead of using it in html form.

Action = url , method = get/post 

How to specify enctype in $.ajax ?

is that enctype = contentype ?

 $.ajax({ type: "post", url: "xyxz/reguser.asp", data: postData, contentType: "multipart/form-data",
 success: function(responseData, textStatus, jqXHR) { alert("data saved") }, error: function(jqXHR, textStatus, errorThrown) { console.log(errorThrown); } })
