InvalidValueError: not an instance of HTMLInputElement

Question

FYI, I'm not a JavaScript Ninja but felt like I'll become one when I did a lot of things based on Google Maps recently.

I implemented a map. User can search for google places and place a marker for it. there's a text box for that. Or user can click on the map to place a marker to the place he's looking for or drag the marker.

Code remains the same. Design changed. Input field's id and name also same. No change to JS code. But this thing ain't working.

Here's the website

Google map is producing an error.

 InvalidValueError: not an instance of HTMLInputElement

I tried solution given here But error still remains.

What could be the possible reason?

Here's the code:

        var map;
        var marker;
        var latLngC;

        function initialize() 
        {
            latLngC = new google.maps.LatLng(14.5800, 121.0000);
            var mapOptions = {
        center: latLngC,
        zoom: 12,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        };

            map = new google.maps.Map(document.getElementById('source_map'),
        mapOptions);

        var marker = new google.maps.Marker({
                position: latLngC,
                map: map,
                draggable: true
            });

            google.maps.event.addListener(marker, 'dragend', function (x) 
            {
            document.getElementById('src_lat').value = x.latLng.lat();
            document.getElementById('src_long').value = x.latLng.lng();
            document.getElementById('pickup_location').innerHTML = x.latLng.lat()+' , '+x.latLng.lng();
                var geocoder = new google.maps.Geocoder;
                var infowindow = new google.maps.InfoWindow;                
            geocodeLatLng(geocoder, map, infowindow,x.latLng.lat(),x.latLng.lng(),'source_point');
            }); 

            //Get coordinates,address Upon clicking a location in map (Source Map)
            //By Sajeev
            google.maps.event.addListener(map, 'click', function(x) 
            {
            document.getElementById('src_lat').value = x.latLng.lat();
            document.getElementById('src_long').value = x.latLng.lng();
            document.getElementById('pickup_location').innerHTML = x.latLng.lat()+' , '+x.latLng.lng();
                var geocoder = new google.maps.Geocoder;
                var infowindow = new google.maps.InfoWindow;                
            geocodeLatLng(geocoder, map, infowindow,x.latLng.lat(),x.latLng.lng(),'source_point');
            });

        //Add marker upon clicking on map
            //google.maps.event.addDomListener(map, 'click', addMarker);
            google.maps.event.addDomListener(map, 'click', function() { addMarker(map); }); 



        var places1 = new google.maps.places.Autocomplete(document.getElementById('source_point'));
        google.maps.event.addListener(places1, 'place_changed', function () {
            var place1 = places1.getPlace();

            var src_addr = place1.formatted_address;
            var src_lat = place1.geometry.location.lat();
            var src_long = place1.geometry.location.lng();

            var mesg1 = "Address: " + src_addr;
            mesg1 += "\nLatitude: " + src_lat;
            mesg1 += "\nLongitude: " + src_long;
            //alert(mesg1);

                 document.getElementById('src_lat').value = src_lat;
            document.getElementById('src_long').value = src_long;
            document.getElementById('pickup_location').innerHTML = src_lat+' , '+src_long;                 
        });
        //Add marker upon place change
        //google.maps.event.addDomListener(places1, 'place_changed', addMarker);            
            google.maps.event.addDomListener(places1, 'place_changed', function() { addMarker(map); }); 

        }
        google.maps.event.addDomListener(window,'resize',initialize);
        google.maps.event.addDomListener(window, 'load', initialize); 

My HTML code looks like this:

   <form role="form" id="frm_source" name="frm_source" method="POST" action="index_action.php">

        <div class="form-group">
            <label for="source_point"><h2>Pickup Address</h2></label>
            <textarea type="text" id="source_point" name="source_point"  class="form-control" placeholder="Enter your pick up address here"></textarea>
        </div>

        <div class="form-group">
            <label for="pickup_location"><h3>GPS Cordinates</h3></label>
            <hr>
            <p id="pickup_location"></p>
        </div>

        <div class="form-group">
            <input type="hidden" id="src_lat" name="src_lat" placeholder="latitude" >
            <input type="hidden" id="src_long" name="src_long" placeholder="longitude" >
        </div>

    <input type="submit" name="submit" id="submit" class="btn btn-primary" value="Next to enter destination address" />
    </form>

Google Map

<div id="source_map"></div>

Your field is TEXTAREA, and from last updates, google maps autocomplete now supports only window.HTMLInputElement (INPUT tag).
