我如何将自动完成与地理编码结合起来以获得纬度。 &液化天然气。从这个自动完成功能的表单输入？

Question

我正在制作此表单，用户在其中输入他们的 post 代码，它 自动完成 来自 google.maps.places 下拉列表的完整地址。唯一缺少的是 latitude 和 longitude，我打算为其创建隐藏字段，然后 onsubmit post 添加到我的 google 工作表电子表格的适当字段中。

我坚持的是将地理编码API调用与自动完成Javascript功能结合起来。我想要做的是添加带有自动完成功能的地理编码 API 调用，以便 Lat。 Lng 被发送到隐藏字段，我已经尝试解决这个问题 3 天了，我想知道是否有人有 解决方案。

这是我的代码：

var placeSearch, autocomplete;
  var componentForm = {
    street_number: 'short_name',
    route: 'long_name',
    locality: 'long_name',
    administrative_area_level_1: 'short_name',
    country: 'long_name',
    postal_code: 'short_name'
  };

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
    /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
    {types: ['geocode']});

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  autocomplete.addListener('place_changed', fillInAddress);
}

function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType]) {
      var val = place.address_components[i][componentForm[addressType]];
      document.getElementById(addressType).value = val;
    }
  }
}

// Bias the autocomplete object to the user's geographical location,
// as supplied by the browser's 'navigator.geolocation' object.
function geolocate() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var geolocation = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }
}

<form id="myform" method="POST" 
              action="https://script.google.com/macros/s/AKfycbzF_r-4ENEXSMD36Ry_gQ9iSQ5dqfpZiw3VytR7LmpSAwxbEcRelxhGJroi8QCBavEI/exec"

                  </div>
                </div>

                <div class="form-group row">
                  <label>Lat</label>
                  <div class="col-sm-4">

                  </div>
                </div>

              </div>
            <div class="form-group row">
              
              <div id="submit">
                <button type="submit" value="Submit" >Submit</button>
              </div>
            </div>
            </form>
            <script
        src="https://maps.googleapis.com/maps/api/js?key=AIzaSyB_MrpX85obMpsk_eEdfE-iPIt06qbHyt0&libraries=places&callback=initAutocomplete"
        async defer></script>

现在我还有调用 google 地理编码 API

的代码片段

 document.getElementById('myform').addEventListener('submit', function(e){
    e.preventDefault(); //prevent form submit
    const place = autocomplete.getPlace(); //get place from autocomplete
    if (!place || !place.geometry) { //check if valid location
      swal("You have provided an Invalid address","Enter a valid Address", "warning");
      return;
    }
    // It is valid, proceed to geocode!
    else {
      // Listen for form submit
      document.getElementById('myForm').addEventListener('submit', geocode);
      function geocode(e){
        // Prevent actual submit
        e.preventDefault();
        var location = document.getElementById('location-input').value; //* I think this is where I might have made a mistake
        axios.get('https://maps.googleapis.com/maps/api/geocode/json', {
            params:{
                address: location,
                key: 'AIzaSyB_MrpX85obMpsk_eEdfE-iPIt06qbHyt0'
            }
        })
        .then(function(response){
            // Log full response
            console.log(response);
    
            // Formatted Address
            var formattedAddress = response.data.results[0].formatted_address;
            
            // Address Components
            var addressComponents = response.data.results[0].address_components;
    
            // Get values from the input fields
            var veg_planted = getInputVal('veg_planted');
        
            // Get geometry 
            var lat = response.data.results[0].geometry.location.lat;
            var lng = response.data.results[0].geometry.location.lng;
            var coords= (formattedAddress + ": " + lat + "," + lng);
            console.log(coords);
    
            // Save messages
            saveMessage(veg_planted, coords);
            
        })
        .catch(function(error){
            console.log(error);
        });
    }
    }
  });

这个功能可以与自动完成功能集成吗我必须让表格填写纬度。和液化天然气。价值观？如果那里有人有解决方案，那将对我有很大帮助。谢谢。

您不需要使用地理编码器。 API returns lat/lng 坐标在其响应中的位置（如果有的话）。

PlaceResult.geometry
geometry optional
Type: PlaceGeometry optional
The Place’s geometry-related information.

PlaceGeometry interface
Defines information about the geometry of a Place.
Properties
location optional
Type: LatLng optional
The Place’s position.

document.getElementById("Lat").value = place.geometry.location.lat();
document.getElementById("Lng").value = place.geometry.location.lng();

工作代码片段：

var placeSearch, autocomplete;
var componentForm = {
  street_number: 'short_name',
  route: 'long_name',
  locality: 'long_name',
  administrative_area_level_1: 'short_name',
  country: 'long_name',
  postal_code: 'short_name'
};

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
    /** @type {!HTMLInputElement} */
    (document.getElementById('autocomplete')), {
      types: ['geocode']
    });

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  autocomplete.addListener('place_changed', fillInAddress);
}

function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    document.getElementById(component).value = '';
    document.getElementById(component).disabled = false;
  }
  document.getElementById("Lat").value = place.geometry.location.lat();
  document.getElementById("Lng").value = place.geometry.location.lng();

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType]) {
      var val = place.address_components[i][componentForm[addressType]];
      document.getElementById(addressType).value = val;
    }
  }
}

// Bias the autocomplete object to the user's geographical location,
// as supplied by the browser's 'navigator.geolocation' object.
function geolocate() {
  if (navigator.geolocation) {
    navigator.geolocation.getCurrentPosition(function(position) {
      var geolocation = {
        lat: position.coords.latitude,
        lng: position.coords.longitude
      };
      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }
}

how do I combine autocomplete with geocode to get Lat. & Lng. from form input in this autocomplete function?

javascript
