如何通过Google Maps API反向地理编码显示所需的元素?

[英]How to display the desired elements from Google Maps API reverse geocoding?

I want to display a specific result using the Google Maps API reverse geocoding. 我想使用Google Maps API反向地理编码显示特定结果。 I'm pulling in what I want in the console, but I'm blanking on pulling it in the display. 我要在控制台中输入想要的内容,但是在将其显示在显示屏中时却空白。

In addition, I can't get the form field to populate with the data. 另外,我无法获取表单字段来填充数据。 It populates in the 它填充在

tag, but doesn't go into the form 标记,但不进入表格

JS JS

   (function() {
        var geocoder = new google.maps.Geocoder(),
            locElement = document.querySelector("#loc"),
            google_coords;
        navigator.geolocation.getCurrentPosition(function(e) {
            google_coords = new google.maps.LatLng(
                e.coords.latitude,
                e.coords.longitude // current address
            );
            geocoder.geocode({ latLng: google_coords }, 
        reverseGeocoderSuccess);
        });

        function reverseGeocoderSuccess(results, status) {
            var address;
            if (status === google.maps.GeocoderStatus.OK) {
                if (results[0]) {
                    var address_components = 
        results[0].address_components;
                    address = results[0].formatted_address;
                    locElement.innerHTML = address;

                    // print desired result to the console:
                    console.log(
                        address_components[3].short_name + ", " +address_components[5].short_name + " " + address_components[7].long_name + ", " + address_components[6].long_name
                    );
                }
            }
        }
    })(); 

HTML 的HTML

<div class="container-fluid">

<form class="form-horizontal" role="form">
    <fieldset class="address">
        <legend>Address</legend>

        <div class="form-group">
            <label class="control-label col-sm-2 col-md-3">
            Location
        </label>
            <div class="col-sm-4 col-md-3">
                <input class="form-control" type="text" id="loc" name="Location" value="" autocomplete="address-level2">
            </div>
        </div>

    </fieldset>
</form>

To have the result appear in the form input box you can replace 要使结果显示在表单输入框中,您可以替换

locElement.innerHTML = address;

with

document.getElementById("loc").value = address;

To display a Google Map with the location (which I think is what you're trying to do) you will have to create a Map object and give it a center of your address coordinates. 要显示具有该位置的Google Map(我认为这是您要尝试的操作),您必须创建一个Map对象,并为其提供地址坐标的中心。 Something like: 就像是:

const map = new google.maps.Map(document.getElementById('map'), {
          center: {
            lat: results[0].geometry.location.lat(), 
            lng: results[0].geometry.location.lng()
          },
            zoom: 8,
        });

For the above to work you will also need to add a div to your HTML with id of map: 为了使上述方法起作用,您还需要在HTML中添加一个ID为map的div:

<div id='map'></div>

You can then also add markers, pop-up boxes etc to the map object. 然后,您还可以将标记,弹出框等添加到地图对象。
