【问题描述】:
我正在使用从 Google 开发者网站 (https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform) 获取的代码,如下所示。使用此代码,Google 自动完成地址列表会在输入第一个字符后出现在地址文本框下方。我希望能够在谷歌列表下拉之前输入 5 个字符。我期待你们中的任何人都可以帮助我实现目标。先感谢您!
// 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;
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());
});
}
}
【问题讨论】:
-
您可以使用 AutocompleteService。每个服务调用将被计为一个请求。服务 = 新的 google.maps.places.AutocompleteService(); service.getQueryPredictions({ input: '伦敦附近的酒店' }, function(predictions, status){}); (阅读更多blog.woosmap.com/…)。唯一需要注意的是退货地址没有邮政编码。
