我正在使用 JQM 为智能手机和平板电脑构建一个网站。我有一个使用gmap3显示 Google 地图的页面。我正在使用@media 根据屏幕分辨率定义#map_canvas 的大小。
一切都运行良好,除了当设备的方向改变时,页面被放大(放大)。我怎样才能解决这个问题?
没有问题的纵向视图(iPhone 4)
当手机旋转时,页面会放大。但是当在横向视图中调用页面时,它看起来很好。
这是我的代码。
<!DOCTYPE html>
<html>
<head>
<title>Map</title>
<meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">
<!--JS and CSS links where removed to save space-->
<script type="text/javascript">
$(function(){
$('#map_canvas').gmap3({
marker:{
latLng:[36.491025,-4.951299],
options:{
center:[36.491025,-4.951299]
},
},
map:{
address:"Puerto Banus, Marbella, Spain",
options:{
zoom:16,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.DROPDOWN_MENU
},
navigationControl: true,
scrollwheel: true,
streetViewControl: true
}
}
});
});
</script>
