问题
I'm trying to add Google Places Autocomplete on my Website. I'm having a problem with binding my search textbox with Autocomplete without the use of instantiating a google map. What I'm trying to do is, I want to use the autocomplete as a text suggestion on my search field. but sadly, all the tutorials I've seen had autcomplete being used along with a google map. Is there any way around this?
Thanks in advance.

Guys you can use following code.
<!DOCTYPE html>
<html>
<head>
<link type="text/css" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500">
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
<script>
var autocomplete;
function initialize() {
autocomplete = new google.maps.places.Autocomplete(
/** @type {HTMLInputElement} */(document.getElementById('autocomplete')),
{ types: ['geocode'] });
google.maps.event.addListener(autocomplete, 'place_changed', function() {
});
}
</script>
</head>
<body onload="initialize()">
<div id="locationField">
<input id="autocomplete" placeholder="Enter your address" onFocus="geolocate()" type="text"></input>
</div>
</body>
</html>
Edit: Google Maps now require an API key for this to work.

This is a pretty old thread but google now requires an API for all of their maps based services and I felt that the code example could be simplified a little.
Inside head element (update code with your input element id attribute):
<script type="text/javascript">
function initAutocomplete() {
// Create the autocomplete object, restricting the search to geographical
// location types.
autocomplete = new google.maps.places.Autocomplete(
/** @type {!HTMLInputElement} */(document.getElementById('YOUR_INPUT_ELEMENT_ID')),
{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();
}
</script>
Inside your page confirm you have a text input with an ID attribute that matches the above script:
<input type="text" id="YOUR_INPUT_ELEMENT_ID" />
Just before the close of your body tag add this script (update with your own API key):
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places&callback=initAutocomplete" async defer></script>
Other notes:
- This is a slightly modified version of the original help/example article found here
- You need an active API key for Google Places API Web Service and to enable Google Maps Javascript API from Google Developer Console

Just replace the Secretkey with your api key.
<head>
<link type="text/css" rel="stylesheet" href="https://fonts.googleapis.com/css?family=Roboto:300,400,500">
<script src="https://maps.googleapis.com/maps/api/js?key=Secretkey&libraries=places" async defer></script>
<script>
var autocomplete;
function initialize() {
autocomplete = new google.maps.places.Autocomplete(
/** @type {HTMLInputElement} */
(document.getElementById('autocomplete')),
{ types: ['geocode'] }
);
google.maps.event.addListener(autocomplete, 'place_changed', function() {});
}
</script>
</head>
<div id="locationField">
<input id="autocomplete" name="location" placeholder="Enter your address" onFocus="geolocate()" type="text"></input>
</div>

See this Google Geo Dev blog post: http://googlegeodevelopers.blogspot.com/2012/05/faster-address-entry-with-google-places.html
It has links to the relevant methods, including Autocomplete.getPlace()
It also notes that, "You are free to use Autocomplete in any application, even if you are not displaying a map. All we ask is that you display the ‘powered by Google’ logo under the text field when you use Autocomplete without a map".

function initialize()
{
var input = document.getElementById('location');
var autocomplete = new google.maps.places.Autocomplete(
/** @type {HTMLInputElement} */(input),
{
types: ['(cities)'],
});
google.maps.event.addListener(autocomplete, 'place_changed', function() {
var place = autocomplete.getPlace();
if (!place.geometry) {
return;
}
//document.getElementById('fLat').value = place.geometry.location.lat();
//document.getElementById('fLong').value = place.geometry.location.lng();
var address = '';
if (place.address_components)
{
address = [
(place.address_components[0] && place.address_components[0].short_name || ''),
(place.address_components[1] && place.address_components[1].short_name || ''),
(place.address_components[2] && place.address_components[2].short_name || '')
].join(' ');
}
LoadEventCategory();
LoadYelpData();
});
}
google.maps.event.addDomListener(window, 'load', initialize);
回答6:
try this also
<script>
google.maps.event.addDomListener(window, 'load', initialize);
function initialize() {
var input = document.getElementById('autocomplete_search');
var autocomplete = new google.maps.places.Autocomplete(input);
autocomplete.addListener('place_changed', function () {
var place = autocomplete.getPlace();
// place variable will have all the information you are looking for.
$('#lat').val(place.geometry['location'].lat());
$('#long').val(place.geometry['location'].lng());
});
}
</script>

You can use below code , just replace key with your gmaps key
