Question

据我所知，谷歌地址自动填充并不会将街道号码和路线（街道名称）合并为一个字段。我想以我的形式这样做，但我的结果是NaN。这是我的代码：

  </head>

<body onload="initialize()">
<div id="locationField">
      <input id="autocomplete" placeholder="Enter your address"
             onFocus="geolocate()" type="text"></input>
    </div>
<table id="address">
  <tr>
    <td>Address</td>
    <td colspan="3"><input class="field" id="address" disabled="true"></input></td>
  </tr>
      <tr>
        <td class="label">Street address</td>
        <td class="slimField"><input class="field" id="street_number"
              disabled="true"></input></td>
        <td class="wideField" colspan="2"><input class="field" id="route"
              disabled="true"></input></td>
      </tr>
      <tr>
        <td class="label">City</td>
        <td class="wideField" colspan="3"><input class="field" id="locality"

和javascript：

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 initialize() {
  // 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.
  google.maps.event.addListener(autocomplete, 'place_changed', function() {
    fillInAddress();
  });
}


// [START region_fillform]
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;
  }
// combine street_number and route to become address
var newAddress = place.address_components.street_number + place.address_components.route;
var el = document.getElementById('address');
el.textContent = newAddress;

  // 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;
    }
  }
}
// [END region_fillform]

// [START region_geolocation]
// 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 = new google.maps.LatLng(
          position.coords.latitude, position.coords.longitude);
      var circle = new google.maps.Circle({
        center: geolocation,
        radius: position.coords.accuracy
      });
      autocomplete.setBounds(circle.getBounds());
    });
  }

没有属性

place.address_components.street_number

和

place.address_components.route

您必须遍历place.address_components并检查types-array是否包含特定功能（如函数末尾的循环中所示）

function fillInAddress() {
  var components  = {
                        street_number: 'short_name',
                        route: 'long_name'
                    },
      address     = [],
      place       = autocomplete.getPlace();

      for (var i = 0; i < place.address_components.length; i++) {
        var addressType = place.address_components[i].types[0];
        if (components[addressType]) {
          var val = place.address_components[i][components[addressType]];
          address[(addressType===route)?'unshift':'push'](val)
        }
      }
      //I simply make an alert, because it's not clear what you're trying to achieve,
      //in your current code the form-fields(except autocomplete)  are redundant
      if(!address.length){
        alert('n/a');
      }
      else{
        alert(address.join(' '));
      }

}

//this combines both street number and street name into a new input section
//with ad id of 'address1'
//here is the HTML input field
//<input type="field" id="address1" aria-required="true">

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

    // Initialize fulladdress for when we combine street number and street name
    var fullAddress="";

    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 then fill-in 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]];
            // retrieve first value (street number)
            switch(i){
                case 0:
                    fullAddress= val;
                    fullAddress= fullAddress.concat(" ");
                    break;
                case 1:
                    fullAddress= fullAddress.concat(val);
                    document.getElementById("address1").value = fullAddress;
                    break;
                default:
                    document.getElementById(addressType).value = val;
                }
            }
        }
