当自动填写地址时，调用谷歌地图的位置ID

由于用于存储位置值的输入元素具有名为results的id属性

<input class="field" id="results" disabled="true"></input> 

你可以把保存位置值的行改成:

document.getElementById('results').value = (place.place_id);

修改示例

// This example displays an address form, using the autocomplete feature
// of the Google Places API to help users fill in the information.
var placeSearch, autocomplete;

  street_number: 'short_name',
  route: 'long_name',
  locality: 'long_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);
}
// [START region_fillform]
function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();
  document.getElementById('results').value = (place.place_id);
  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;
    }
