我有id="Pickup Location"
和id="Drop Location"
这两个字段。我想用印度城市的名称自动完成字段。
<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谷歌API代码,它工作得很完美。但是,JS是为输入字段编写的,只能与id="autocomplete"
一起工作。
那么现在,我如何重写JS,使它同时接受Pick Location
和Drop Location
呢?
PS:我不需要id=autocomplete
字段,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());
});
}
}

这段代码需要做一些修改,所以我将保持它的基本性。
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,我已经删除了这些代码。geolocate()
函数看起来只用于在Map上绘图,而您的代码中没有这个函数,因此我删除了它。所以下面的内容只适用于自动完成。你仍然需要弄清楚如何通过谷歌MapAPI只返回印度城市。

下面的代码应该可以根据你的要求为你工作!确保你写的表单填写过程工作正常
