将 Google Maps Place Form 集成到自动完成地址表单 javascript

Question

我正在尝试将此Place Form 集成到此Autocomplete address form 中。但我未能使这两项工作。目前它只适用于地址完整的表格，地图加载，但它不会自动指向输入的位置。请帮助我，我是 javascript 的菜鸟。 这是我正在研究的小提琴：http://jsfiddle.net/qrAGU/。非常感谢您的帮助。

JS：

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() {
    var mapOptions = {
center: new google.maps.LatLng(-33.8688, 151.2195),
zoom: 13
    };
    var map = new google.maps.Map(document.getElementById('map-canvas'),
    mapOptions);
    var input = (
    document.getElementById('autocomplete'));
    /*
var types = document.getElementById('type-selector');
map.controls[google.maps.ControlPosition.TOP_LEFT].push(input);
map.controls[google.maps.ControlPosition.TOP_LEFT].push(types);*/
// tried also moving the comment only for types, but still nothing  
    autocomplete = new google.maps.places.Autocomplete(
    input,
    { 
types: ['geocode'] 
    }
    );
    google.maps.event.addListener(autocomplete, 'place_changed', function() {
        fillInAddress();
        infowindow.close();
        marker.setVisible(false);
        autocomplete.bindTo('bounds', map);
        var place = autocomplete.getPlace();
        if (!place.geometry) {
            return;
        }
    });
    if (place.geometry.viewport) {
        map.fitBounds(place.geometry.viewport);
    } else {
        map.setCenter(place.geometry.location);
        map.setZoom(17);  // Why 17? Because it looks good.
    }
    marker.setIcon(/** @type {google.maps.Icon} */({
url: place.icon,
size: new google.maps.Size(71, 71),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(17, 34),
scaledSize: new google.maps.Size(35, 35)
    }));
    marker.setPosition(place.geometry.location);
    marker.setVisible(true);
    var address = '';
    if (place.address_components) {
        address = [
        (place.address_components[0] && place.address_components[0].short_name || ''),
        (place.address_components[1] && place.address_components[1].short_name || ''),
        (place.address_components[2] && place.address_components[2].short_name || '')
        ].join(' ');
    }

    infowindow.setContent('<div><strong>' + place.name + '</strong><br>' + address);
    infowindow.open(map, marker);
    //});

    // Sets a listener on a radio button to change the filter type on Places
    // Autocomplete.
    function setupClickListener(id, types) {
        var radioButton = document.getElementById(id);
        google.maps.event.addDomListener(radioButton, 'click', function() {
            autocomplete.setTypes(types);
        });
    }

}
google.maps.event.addDomListener(window, 'load', initialize);
// [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;
    }

    // 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);
            autocomplete.setBounds(new google.maps.LatLngBounds(geolocation,
            geolocation));
        });
    }
}

同时更新地图和表单，希望对你有帮助
