Google Maps - Trigger Search Box on button click

I'm interested in implementing a Google Maps search button with a 'Submit'/'Go' button next to it (such as on http://maps.google.com). Everything works great if I press Enter in the search box, but I have no idea how to force/submit the search using the button.

Right now I have my code based on the example on: https://developers.google.com/maps/documentation/javascript/examples/places-searchbox . The most important part is that I'm using this for now:

HTML:

<div id="intro-search">
    <input id="search-box" />
    <button type="button">Submit!</button>
</div>

JS:

  // Listen for the event fired when the user selects an item from the
  // pick list. Retrieve the matching places for that item.
  google.maps.event.addListener(searchBox, 'places_changed', function() {
    // ... 
    // Show the results on the map
    // ...
  }

I have no idea how to trigger the same thing on a button click.

On another note, what is the difference between the SearchBox and the Autocomplete controls? Don't they do the same thing?

To build on Alex Beauchemin's and Scott Butler's answers, a non-Angular, non-jQuery option that works for me today (but may not in the future) is:

document.getElementById('my-button').onclick = function () {
  var input = document.getElementById('my-input');

  function noop() {}

  google.maps.event.trigger(input, 'focus', {});
  google.maps.event.trigger(input, 'keydown', {
    keyCode: 40, // arrow down
    stopPropagation: noop, // because these get called
    preventDefault: noop,
  });  
  google.maps.event.trigger(input, 'keydown', { keyCode: 13 });  // enter
  google.maps.event.trigger(this, 'focus', {});
};

Thought I'd share this in case someone finds this thread as I did. This seemed to work for me. This is a directive I made. So i on your input, you can use

<input id="txtLocation" places-auto-complete autocomplete-select-first-on-enter>

.

app.directive('autocompleteSelectFirstOnEnter', function() {
    //Requires jquery.simulate
    return function(scope, element, attrs) {
        element.bind("keydown", function(e) {
            if(e.which === 40){
                //if they already clicked down, we don't want to click down again
                element.triggered = true;
            }
            if(e.which === 13 && !element.triggered) {
                //They clicked enter, and haven't clicked down yet, and its not recursive
                element.triggered = true; //keep it from being recursive
                $("input#" + element[0].id).trigger('focus');
                $("input#" + element[0].id).simulate('keydown', { keyCode: 40 } ).simulate('keydown', { keyCode: 13 });
                element.triggered = false; //reset it
            }
        });
        element.bind("focus", function(e) {
            //reset it when they click in the field
            element.triggered = false;
        });
    };
});

Add a click listener for your button inside the initialize function.

Something like :

document.getElementById("buttonId").onclick = function(){
    var places = searchBox.getPlaces();
}

With that you have access to the searchbox object exactly like in the places_changed listener of the searchbox.
