回答1:

Here is the code above in a working fiddle -> http://jsfiddle.net/wgur1z7n/ (bootstrap 3.3.5)

Trigger the google maps resize event after the modal is shown :

$('#contact').on('shown.bs.modal', function () {
    google.maps.event.trigger(map, "resize");
});


回答2:

Triggering "resize" did not work for me. The map showed up, but with wrong coordinates and wrong zoom level. You probably have an initMap function on your page. This worked for me:

<script>
    $('#myModal').on('shown.bs.modal', function () {
        initMap();
    });
</script>
