set google origin search box address with a variable-CodePudding

I'm trying to make origin SearchBox destination be string with legit direction, but when I do so I still need to select the first option for it to work (to calculate distance).

Got the this searching around to calculate distance between 2 points and it works perfectly:

But what happens is that I still have to click on the origin search box then this list all possible locations which in my case is the first one, how can I make the map either auto select the first option or recognize the address that is set in the input value?

    <script>

   var map = new google.maps.Map(document.getElementById('map-canvas'), {
  center: {
  lat: 9.0271554,
   lng: 79.4816371
         },
         zoom: 15
        });

     var marker = new google.maps.Marker({
     map: map,
     draggable: false
   });


      if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {

  map.setCenter(initialLocation);

CodePudding user response：

You can call the places service to get the PlaceId (with your string), then pass that placeId into the constructor for your AutocompleteDirectionsHandler or if you already have the PlaceId (you are allowed to store those), just use it, although you probably want to initialize the origin input with the string.

  var origin = "Allbrook, Panama";
  var originInput = document.getElementById('orign');
  originInput.value = origin;
  const request = {
    query: origin,
    fields: ["name", "geometry", "place_id"],
  };
  var originPlaceId;
  var service = new google.maps.places.PlacesService(map);
  service.findPlaceFromQuery(request, (results, status) => {
    if (status === google.maps.places.PlacesServiceStatus.OK && results) {
      originPlaceId = results[0].place_id;
      console.log("placeId=" originPlaceId " coords=" results[0].geometry.location.toUrlValue(6));
      new AutocompleteDirectionsHandler(map, originPlaceId);
      map.setCenter(results[0].geometry.location);
    }
  });

Add the initial origin placeId to the AutocompleteDirectionsHandler constructor:

function AutocompleteDirectionsHandler(map, originPlaceId) {
  this.map = map;
  this.originPlaceId = originPlaceId;
  // ...

let map;
function initMap() {
  map = new google.maps.Map(document.getElementById('map-canvas'), {
