javascript - 设置变量，而不是让最终用户从 html 表单中输入它们

Question

我试图设置这些变量（to、from 和 mode），而不是让用户输入它们。我错过了什么步骤？

var from = (40.750484, -111.811177);
var to = (40.775041, -111.718560);
var mode = driving;

//$('#directions-form').submit(function(e) {
  //$('#error').hide();
  ds.route({
    origin: from,
    destination: to,
    travelMode: mode
  }, function(result, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      fitBounds = true;
      dr.setDirections(result);
    }
    else {
      $('#error').text(status).show();
    }
    recalcHeight();
  });
  e.preventDefault();
  return false;
});

ds.route(from,to,mode);

尝试...

var from = new google.maps.LatLng(40.750484, -111.811177);
var to = new google.maps.LatLng(40.775041, -111.718560);
var mode = google.maps.TravelMode.DRIVING;
