I do it with this simple examps
jQuery
$('.map').click(function(){
$(this).find('iframe').addClass('clicked')
}).mouseleave(function(){
$(this).find('iframe').removeClass('clicked')
});
CSS
.map {
width: 100%;
}
.map iframe {
width: 100%;
display: block;
pointer-events: none;
position: relative; /* IE needs a position other than static */
}
.map iframe.clicked {
pointer-events: auto;
}
Or use the gmap options
function init() {
var mapOptions = {
scrollwheel: false,
