use this for your javascript code:

$(document).ready(function() {

  jQuery.validator.addMethod("noSpace", function(value, element) { 
     return value.indexOf(" ") < 0 && value != ""; 
  }, "Space are not allowed");

  $("#myform").validate({
    errorLabelContainer: $("#error"),
    rules: {
      fname: { required: true, noSpace: true },
      lname: { required: true, noSpace: true }
    },
    messages: {
      fname: { required: 'Please enter your name' },
      lname : { required: "Please enter your last name" }
    }
  });

  $('#submit').click(function() {
    var valid = $("#myform").valid();
    if(!valid) {
      return false;
    }
    $.ajax({
      beforeSend: function() {
        // display loading message
      },
      type: "POST",
      url: 'save',
      data:  $('#formdata').serialize(),
      dataType: 'json',
      cache: false,
      success: function(result) {
        if(result.error) {
          // show error message
        }
        else {
          // redirect to another page
        }
      },
      error: function (response, desc, exception) {
        // show ajax error
      },
      complete: function() {
        // hide loading message
      }
    });
  });
});
