This question already has an answer here:
I'm using a Google Places Autocomplete and I simply want it to select the top item in the results list when the enter key is pressed in the form field and suggestions exist. I know this has been asked before:
Google maps Places API V3 autocomplete - select first option on enter
Google maps Places API V3 autocomplete - select first option on enter (and have it stay that way)
But the answers in those questions don't seem to actually work, or they address specific added functionality.
It also seems like something like the following should work (but it doesn't):
$("input#autocomplete").keydown(function(e) {
if (e.which == 13) {
//if there are suggestions...
if ($(".pac-container .pac-item").length) {
//click on the first item in the list or simulate a down arrow key event
//it does get this far, but I can't find a way to actually select the item
$(".pac-container .pac-item:first").click();
} else {
//there are no suggestions
}
}
});
Any suggestions would be greatly appreciated!
I've read the many answers of this question, and of the linked questions' answers so many times, before finding that the best answer is this one (Nota: sadly, it's not the accepted answer!).
I've modified 2 or 3 lines to turn it into a ready-to-use function that you can copy/paste in your code and apply to many input elements if needed. Here it is:
var selectFirstOnEnter = function(input){
// store the original event binding function
var _addEventListener = (input.addEventListener) ? input.addEventListener : input.attachEvent;
// Simulate a 'down arrow' keypress on hitting 'return' when no pac suggestion is selected, and then trigger the original listener.
function addEventListenerWrapper(type, listener) {
if (type == "keydown") {
var orig_listener = listener;
listener = function (event) {
var suggestion_selected = $(".pac-item-selected").length > 0;
if (event.which == 13 && !suggestion_selected) {
var simulated_downarrow = $.Event("keydown", { keyCode:40, which:40 });
orig_listener.apply(input, [simulated_downarrow]);
}
orig_listener.apply(input, [event]);
};
}
// add the modified listener
_addEventListener.apply(input, [type, listener]);
}
if (input.addEventListener) {
input.addEventListener = addEventListenerWrapper;
} else if (input.attachEvent) {
input.attachEvent = addEventListenerWrapper;
}
}
Usage:
selectFirstOnEnter(input1);
selectFirstOnEnter(input2);
...
I am reposting my answer from Google maps Places API V3 autocomplete - select first option on enter:
It seems there is a much better and clean solution: To use google.maps.places.SearchBox instead of google.maps.places.Autocomplete.
A code is almost the same, just getting the first from multiple places. On pressing the Enter the the correct list is returned - so it runs out of the box and there is no need for hacks.
See the example HTML page:
The relevant code snippet is:
var searchBox = new google.maps.places.SearchBox(document.getElementById('searchinput'));
google.maps.event.addListener(searchBox, 'places_changed', function() {
var place = searchBox.getPlaces()[0];
if (!place.geometry) return;
if (place.geometry.viewport) {
map.fitBounds(place.geometry.viewport);
} else {
map.setCenter(place.geometry.location);
map.setZoom(16);
}
});
The complete source code of the example is at: https://gist.github.com/klokan/8408394
In my site to achieve this same functionality I neeeded the jQuery simulate plugin (https://github.com/jquery/jquery-simulate) and then attach the event:
$("input#autocomplete").focusin(function () {
$(document).keypress(function (e) {
if (e.which == 13) {
$("input#autocomplete").trigger('focus');
$("input#autocomplete").simulate('keydown', { keyCode: $.ui.keyCode.DOWN } ).simulate('keydown', { keyCode: $.ui.keyCode.ENTER });
}
});
});
The plugin will simulate the action of press the key DOWN and then ENTER, ENTER itself does not work and I couldn't find another way to select the first option.
Hope this helps
Working Solution that listens to if the user has started to navigate down the list with the keyboard rather than triggering the false navigation each time
https://codepen.io/callam/pen/RgzxZB
Here are the important bits
// search input
const searchInput = document.getElementById('js-search-input');
// Google Maps autocomplete
const autocomplete = new google.maps.places.Autocomplete(searchInput);
// Has user pressed the down key to navigate autocomplete options?
let hasDownBeenPressed = false;
// Listener outside to stop nested loop returning odd results
searchInput.addEventListener('keydown', (e) => {
if (e.keyCode === 40) {
hasDownBeenPressed = true;
}
});
// GoogleMaps API custom eventlistener method
google.maps.event.addDomListener(searchInput, 'keydown', (e) => {
// Maps API e.stopPropagation();
e.cancelBubble = true;
// If enter key, or tab key
if (e.keyCode === 13 || e.keyCode === 9) {
// If user isn't navigating using arrows and this hasn't ran yet
if (!hasDownBeenPressed && !e.hasRanOnce) {
google.maps.event.trigger(e.target, 'keydown', {
keyCode: 40,
hasRanOnce: true,
});
}
}
});
// Clear the input on focus, reset hasDownBeenPressed
searchInput.addEventListener('focus', () => {
hasDownBeenPressed = false;
searchInput.value = '';
});
// place_changed GoogleMaps listener when we do submit
google.maps.event.addListener(autocomplete, 'place_changed', function() {
// Get the place info from the autocomplete Api
const place = autocomplete.getPlace();
//If we can find the place lets go to it
if (typeof place.address_components !== 'undefined') {
// reset hasDownBeenPressed in case they don't unfocus
hasDownBeenPressed = false;
}
});
This is what I've done and it works:
HTML:
<input name="location" id="autocomplete" autocomplete="off" type="text" class="textbx" placeholder="Enter Destination" required>
googleautocompletecustomized.js:
function initialize() {
// Create the autocomplete object, restricting the search
// to geographical location types.
if($('#autocomplete').length){
autocomplete = new google.maps.places.Autocomplete(
(document.getElementById('autocomplete')),
{
types: ['(regions)'],
componentRestrictions: {country: "in"}
});
google.maps.event.addListener(autocomplete, 'place_changed', function() {
$('#autocomplete').closest('form').data('changed', true);
fillInAddress();
});
}
//select first result
$('#autocomplete').keydown(function (e) {
if (e.keyCode == 13 || e.keyCode == 9) {
$(e.target).blur();
if($(".pac-container .pac-item:first span:eq(3)").text() == "")
var firstResult = $(".pac-container .pac-item:first .pac-item-query").text();
else
var firstResult = $(".pac-container .pac-item:first .pac-item-query").text() + ", " + $(".pac-container .pac-item:first span:eq(3)").text();
var geocoder = new google.maps.Geocoder();
geocoder.geocode({"address":firstResult }, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
placeName = results[0];
e.target.value = firstResult;
fillInAddress(placeName);
$('#datetimepicker1 .input-group-addon').click();
}
});
}
});
}
// [START region_fillform]
function fillInAddress(place) {
// Get the place details from the autocomplete object.
if(!place)
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;
}
}
}
This is the easiest way that solved to me:
autocomplete.addListener('place_changed', function() {
if(event.keyCode == 13 || event.keyCode == 9) { // detect the enter key
var firstValue = $(".pac-container .pac-item:first").text(); // assign to this variable the first string from the autocomplete dropdown
}
$('#search-address').val(firstValue); // add this string to input
console.log(firstValue); // display the string on your browser console to check what it is
//(...) add the rest of your code here
});
}
If you are using the Angular 2,4, 5 & 6, Please find the answer in this below link
Put the input-element outside the form-element. Populate the form with javascript.
document.getElementById("adress").value = place.formatted_address;
I did some work around this and now I can force select 1st option from google placces using angular js and angular Autocomplete module.
