我有两个字段:id="Pickup Location"
和 id="Drop Location"
。我想自动填写包含印度城市名称的字段。
<input type="text" value="" name="form[Pickup Location]" id="Pickup Location" onfocus="geolocate()" class="rsform-input-box">
<input type="text" value="" name="form[Drop Location]" id="Drop Location" onfocus="geolocate()" class="rsform-input-box">
我有这个自动完成的 Google API 代码,并且运行完美。但是,JS 是为输入字段编写的,仅适用于 id="autocomplete"
。
那么现在,我该如何重写 JS,使其同时接受 Pick Location
和 Drop Location
呢?
PS:我不需要 id=autocomplete
字段,并将丢弃它。
<input id="autocomplete" onFocus="geolocate()" type="text">
<script>
// This example displays an address form, using the autocomplete feature
// of the Google Places API to help users fill in the information.
// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">
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());
});
}
}
</script>

最佳答案
该代码需要进行相当多的更改,因此我将保持基本内容。
fillInAddress()
函数需要 html 元素来存储两个位置的值。由于这些元素不存在,我已删除该代码。
geolocate()
函数看起来仅用于在 map 上绘图,这在您的代码中不存在,因此我将其删除。
因此以下内容仅适用于自动完成。您仍然需要弄清楚如何通过谷歌地图 API 仅返回印度城市。
var placeSearch, pickupLocation, dropLocation;
function initAutocomplete() {
// Create the autocomplete object, restricting the search to geographical
// location types.
pickupLocation = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */
(document.getElementById('Pickup_Location')), {
types: ['geocode']
});
dropLocation = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */
(document.getElementById('Drop_Location')), {
types: ['geocode']
});
}
<input type="text" value="" name="form[Pickup Location]" id="Pickup_Location" placeholder="Pickup Location" class="rsform-input-box">
<input type="text" value="" name="form[Drop Location]" id="Drop_Location" placeholder="Drop Location" class="rsform-input-box">
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyADbpfJGWwRh5um_gd2gNySgrI5FAy2RZk&libraries=places&callback=initAutocomplete" async defer></script>
