我使用的代码取自 Google 开发者网站 (https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform),如下所示。使用此代码,在键入第一个字符后,google 自动完成地址列表将出现在地址文本框下方。我希望能够在 google 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我的目标。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());
});
}
}

客户希望仅在输入超过 2 个字符时才触发自动完成。 我找不到“开箱即用”的解决方案(功能请求在 Google 代码上的 https://code.google.com/p/gmaps-api-issues/issues/detail?id=10367 打开)。
感谢 Zme...@gmail.com ( https://code.google.com/p/gmaps-api-issues/issues/detail?id=3429 ),我可以制定出以下满足需求的解决方案。
if (1 < query.length) { // if 2 chars or more entered
if (undefined == self.googleAutocomplete) { //... and Google Autocomplete not set yet
console.debug('trigger autocomplete !');
self.googleAutocomplete = new google.maps.places.Autocomplete(self.HtmlElement, self.settings.google_options);
}
// ! Beware : with 2 chars => we are only SETTING the autocompletion : actual suggestions will start from 3rd char...
google.maps.event.addListener(self.googleAutocomplete, 'place_changed', function () {
// do whatever with suggestion selected...
}
} else if (undefined != self.googleAutocomplete) { // if less than 2 chars
console.debug('unbind autocomplete !');
// removing autocompletion : Thx to Zme...@gmail.com
//... on https://code.google.com/p/gmaps-api-issues/issues/detail?id=3429
$(".pac-container").remove();
google.maps.event.clearListeners(self.HtmlElement);
self.googleAutocomplete = undefined;
}
虽然它对我有用,但我仍然认为通过如此繁重的对象实例化/删除只是为了激活/禁用自动完成是一种耻辱。 不要犹豫,投票赞成在 Google Autocompletion Api 中实现这样的功能 https://code.google.com/p/gmaps-api-issues/issues/detail?id=10367 ,如果您认为它有用。
祝你有个美好的一天
