输入5个字符后，Google Place自动填充地址表单 [英] Google Place Autocomplete Address Form after typing 5 characters
问题描述
我使用的是Google开发者网站提供的代码（ https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform ），如下所示。使用此代码，在输入第一个字符后，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列表下拉之前键入5个字符。我期待着你们中的任何人都能帮助我实现我的目标。先谢谢你！
//此示例使用Google Places API的自动填充功能
//来显示地址表单用户填写信息。
var placeSearch，autocomplete;
var componentForm = {
street_number：'short_name'，
route：'long_name'，
locality：'long_name'，
administrative_area_level_1：'short_name'，
国家：'long_name'，
postal_code：'short_name'
};
函数initAutocomplete（）{
//创建自动填充对象，将搜索限制为地理区域
//位置类型。
autocomplete = new google.maps.places.Autocomplete（
/ ** @type {！HTMLInputElement} * /（document.getElementById（'autocomplete'）），
{types：['地理编码']}）;
//当用户从下拉列表中选择一个地址时，填写表单中的地址
//字段。
autocomplete.addListener（'place_changed'，fillInAddress）;
}
函数fillInAddress（）{
//从自动填充对象中获取地点详细信息。
var place = autocomplete.getPlace（）;
（componentForm中的var组件）{
document.getElementById（component）.value ='';
document.getElementById（component）.disabled = false;
}
//从地点详细信息
//获取地址的每个组成部分，然后填写表单中相应的字段。
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;
}
}
}
//将自动完成对象偏移到用户的地理位置
//，由浏览器的'navigator.geolocation '对象。
函数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（））;
}）;
}
}
A客户希望仅在输入超过2个字符时触发自动完成功能。
我找不到开箱即用解决方案（功能请求已在 https://code.google.com/p/gmaps-api-issues/issues/detail？id = 10367 on Google Code）。
Thx to Zme ... @ gmail.com（ https://code.google.com/p/gmaps-api-issues/issues/detail?id=3429 ），我可以制定出满足如果（1< query.length）{//如果输入2个字符或更多字符
if（（$ <$ p
$> undefined == self.googleAutocomplete）{// ...和Google Autocomplete尚未设置
console.debug（'trigger autocomplete！'）;
self.googleAutocomplete = new google.maps.places.Autocomplete（self.HtmlElement，self.settings.google_options）;
}
//！注意：2个字符=>我们只是设置自动完成：实际的建议将从第三个字符开始...
google.maps.event.addListener（self.googleAutocomplete，'place_changed'，function（）{
//做任何事建议选择...
}
} else if（undefined！= self.googleAutocomplete）{//如果小于2个字符
console.debug（'unbind autocomplete！'）;
//移除自动完成：Thx至Zme ... @ gmail.com
// ...在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，但我仍然认为通过这样重的物体是一种耻辱实例/删除只是为了activa te /取消自动完成。
请不要犹豫，您可以投票支持在Google Autocompletion API中实现此功能 https://code.google.com/p/gmaps-api-issues/issues/detail?id=10367 ，如果您认为它有用。
祝你有美好的一天
I am using the code taken from the Google Developer website (https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform), which is indicated below. With this code, the google autocomplete address list appears below the address text-box just after typing the first character. I would like to be able to type 5 characters before the google list drops down. I look forward anyone of you could help me to get my aim. Thank you in advance!
// 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());
});
}
}
A customer wanted to have autocompletion triggered only if more than 2 chars were entered. I could not find an "out-of-the-box" solution (feature request opened at https://code.google.com/p/gmaps-api-issues/issues/detail?id=10367 on Google Code).
Thx to Zme...@gmail.com (https://code.google.com/p/gmaps-api-issues/issues/detail?id=3429), I could work out following solution that fulfills the need.
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;
}
Although it worked for me, I still think it is a shame to go through such heavy object instanciation/deletion just to activate/disactivate autocompletion. Do not hesitate to vote in favor of having such a feature implemented in Google Autocompletion Api at https://code.google.com/p/gmaps-api-issues/issues/detail?id=10367, if you deem it usefull.
Have a good day
