Google Autocomplete Places API not triggering event on change via TAB

Question

Per the Google Autocomplete Places API documentation, the getPlace() call should return a Places object with all the location data, or, if that place doesn\'t e

Answer 1

pac-input being your place search input, you can do the following:

// Trigger search on blur
document.getElementById('pac-input').onblur = function () {

    google.maps.event.trigger(this, 'focus', {});
    google.maps.event.trigger(this, 'keydown', {
        keyCode: 13
    });
};

Or with a google maps event listener:

// Trigger search on blur
google.maps.event.addDomListener(document.getElementById("pac-input"), 'blur', function() {

    google.maps.event.trigger(this, 'focus', {});
    google.maps.event.trigger(this, 'keydown', {
        keyCode: 13
    });
});

Edit: As mentioned in the comments, this messes up with the "normal behavior" of a user selecting a place by mouse click.

Below is a complete example using pure Javascript. For a (simpler) jQuery solution, look at @ChrisSnyder's answer.

function initialize() {

  var ac = new google.maps.places.Autocomplete(
    (document.getElementById('autocomplete')), {
      types: ['geocode']
    });

  ac.addListener('place_changed', function() {

    var place = ac.getPlace();

    if (!place.geometry) {

      // User entered the name of a Place that was not suggested and
      // pressed the Enter key, or the Place Details request failed.
      console.log("No details available for input: '" + place.name + "'");
      return;
    }

    console.log("You selected: '" + place.formatted_address + "'");
  });

  // Trigger search on blur
  google.maps.event.addDomListener(document.getElementById("autocomplete"), 'blur', function() {

    // Find the pac-container element
    var pacContainer = nextByClass(this, 'pac-container');

    // Check if we are hovering on one of the pac-items
    // :hover propagates to parent element so we only need to check it on the pac-container
    // We trigger the focus and keydown only if :hover is false otherwise it will interfere with a place selection via mouse click
    if (pacContainer.matches(':hover') === false) {

      google.maps.event.trigger(this, 'focus', {});
      google.maps.event.trigger(this, 'keydown', {
        keyCode: 13
      });
    }

  });
}

function hasClass(elem, cls) {
  var str = " " + elem.className + " ";
  var testCls = " " + cls + " ";
  return (str.indexOf(testCls) != -1);
}

function nextByClass(node, cls) {
  while (node = node.nextSibling) {
    if (hasClass(node, cls)) {
      return node;
    }
  }
  return null;
}

#autocomplete {
  width: 300px;
}

<script src="https://maps.googleapis.com/maps/api/js?libraries=places&callback=initialize&key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk" async defer></script>
<input id="autocomplete" placeholder="Enter your address" type="text"></input>

Answer 2

Apparently something changed and the above code is not working the last days, and the following exception appeared in the console

 undefined is not an object (evaluating 'a.handled=!0')

You need to add an empty object on the trigger of the focus event

var inputSearch = document.getElementById('pac-input');

google.maps.event.trigger(inputSearch, 'focus', {})
google.maps.event.trigger(inputSearch, 'keydown', {
    keyCode: 13
});

The following expands on @MrUpsidown's solution but tries to avoid messing with the user when they click on an item in the dropdown as mentioned by @Jkk.jonah

// Trigger search on blur
google.maps.event.addDomListener(document.getElementById("pac-input"), 'blur', function() {
  if (jQuery('.pac-item:hover').length === 0 ) {
    google.maps.event.trigger(this, 'focus', {});
    google.maps.event.trigger(this, 'keydown', {
        keyCode: 13
    });
  } 
});
