Autocomplete Location on Form

Recommended Posts

Is there a way to create a Squarespace form with a location field that autocompletes as a person types in their address? My client wants this feature so people will enter more accurate addresses. I know how to do this when I'm building a form from scratch, but I can't figure out if this can be done with a Squarespace form. I would greatly appreciate any advice!

It may be possible. Its depends on the form.

In general you will need to attach a handler to the field of interest to handle the auto-complete.

Please post the URL for a page on your site where we can see your issue.

If your site is not public please set up a site-wide password, if you've not already done so.

Post the password here.

Adding a site-wide password does not allow anyone to alter your site. It only allows those with the password to see your site. Please read the documentation at the link provided to understand how it works.

Please read the documentation at the link provided on how to share a link to your site to understand how it works. A link to the backend of the your site won’t work for us, i.e. a url that contains /config/.

We can then take a look at your issue.

This is not a solution but a shell of a script that can get you started.

This shows how you can wait for the page to be mostly loaded. Then add an event listener to an input element.

Let us know how it goes.

Since I spent a few hours on this, I figured I'd give back to the community. Here is the JS you have to inject in the "Advanced" header section of the page with the form - this will need extra work if you have more than the form as an input field on the page and this is tailored for Canada but you get the idea. I make no apologies for the beginner code 🙂


let input_line = null
let componentForm = {
  street_number: ['short_name', null],
  route: ['long_name', null],
  locality: ['long_name', null],
  administrative_area_level_1: ['short_name', null],
  country: ['long_name', null],
  postal_code: ['short_name', null]

const options = {
  componentRestrictions: { country: "ca" },
  fields: ["address_components", "geometry", "icon", "name"],
  strictBounds: false,

let line1 = null;
let line2 = null;
let city = null;
let state = null;
let zip = null;

let autocomplete = null
let mapsLibLoaded = false;
document.addEventListener ( 'DOMContentLoaded', ( ) => {
  window.addEventListener('load', function(){
    const selector2 = 'input[id*="address-"]';
    const elements = document.querySelectorAll ( selector2 );
    if (elements != null) {
      Array.prototype.forEach.call(elements, function(element) {
        console.log( " adding a listener to " + element.id)
        if (element.id.includes("line1")) line1 = element;
        else if (element.id.includes("line2")) {
          line2 = element;
          line2.disabled = true
        else if (element.id.includes("city")) {
          city = element;
          city.disabled = true;
        else if (element.id.includes("state")) {
          state = element;
          state.disabled = true
        else if (element.id.includes("zip")) {
          zip = element;
          zip.disabled = true
    } else {
      console.log("Didn't find the element");
    //lazy load initialize google maps because the fields in sqarespace dont seem to exist before this.
    let script = document.createElement('script');
    script.onload = function() {
      mapsLibLoaded = true;
    script.src = "https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places&callback=initialize&key=<YOUR KEY HERE>";
  } );
  } );

function initialize() {
  if (line1 != null) {
    console.log("Loading google");
    autocomplete = new google.maps.places.Autocomplete(line1, options);
    autocomplete.addListener('place_changed', fillInAddress);
  } else {
    console.log("Unable to load google");

function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();
  if (place == null) {
    console.log("No place");

  //don't bother clearing value since this is managed by react
  line1.disabled = false;
  line2.disabled = false;
  city.disabled = false;
  state.disabled = false;
  zip.disabled = false;

  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][0]];
      console.log("Found " + componentForm[addressType][0] + " " + val)
      componentForm[addressType][1] = val

  var street_num = componentForm['street_number'][1]; //street number
  var street_name = componentForm['route'][1]; //route
  var city_name = componentForm['locality'][1]; //locality
  var province_name = componentForm['administrative_area_level_1'][1]; //admin region
  var postal_code = componentForm['postal_code'][1]; //post code

  //Remove the listener while we update the component via react. You only get one chance since i'm not sure how to add again...
  set_value(line1, street_num + " " + street_name);
  set_value(city, city_name);
  set_value(state, province_name);
  set_value(zip, postal_code);

  autocomplete = new google.maps.places.Autocomplete(line1, options);
  autocomplete.addListener('place_changed', fillInAddress);

function set_value(component, value_string) {
  //Deal with React shenanigans
  var nativeInputValueSetter = Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, "value").set;
  nativeInputValueSetter.call(component, value_string);
  var inputEvent = new Event('input', { bubbles: true});
