javascript - Google map modal issue

Question

I am trying to display google map into the Twitter bootstrap modal. When user first click on the button Show map then he is able to see the map successfuly as i am generating the map onclick() function but when he closes the modal and reopen it then the map doesnot show properly and 90% part of the map goes grey like following

I even try this workaround that remove that whole div in which the map is bind and regenerate it but that trick doesnot work too kindly let me know how can i resolve my issue.

Following is my js function which i am calling onclick event of show map

function mapp()
{

//google.maps.event.trigger(map, "resize");
  //$("#map_google_canvas").empty();
$("#map_google_canvas").remove();

$("#crmap").append("<div id='map_google_canvas'></div>")


    var myOptions = {
        center: new google.maps.LatLng(54, -2),
        zoom: 6,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };

    var map = new google.maps.Map(document.getElementById("map_google_canvas"), myOptions);

        var addressArray = new Array("London, United Kingdom", "London Road, Brentwood, United Kingdom", "Brentwood, United Kingdom");


    var geocoder = new google.maps.Geocoder();

    var markerBounds = new google.maps.LatLngBounds();

    for (var i = 0; i < addressArray.length; i++) {
        geocoder.geocode({
            'address': addressArray[i]
        }, function (results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                var marker = new google.maps.Marker({
                    map: map,
                    position: results[0].geometry.location
                });
                markerBounds.extend(results[0].geometry.location);
                map.fitBounds(markerBounds);
            } else {
                alert("Geocode was not successful for the following reason: " + status);
            }
        });
    }


}

Kindly help,

Thanks

I had the same issue. but I found an issue with modal shown event. as its not working with some version of issue so I just follow the bootstrap modal documentation to achieve it.

Bootstrap Modal Map Issue Solution :

$(document).ready(function(){
  $('#locationMap').on('shown.bs.modal', function(){
    google.maps.event.trigger(map, 'resize');
    map.setCenter(new google.maps.LatLng(-33.8688, 151.2195));
  });
});

Finally This works for me, It could help to someone.
