更改浏览器大小后显示Google地图 [英] Google map appears after browser size changes

问题描述

问题是，当我使用以下包含客户端密钥的代码时， 拳头进入页面显示空的Google地图，如果我调整浏览器大小，地图就会出现.

The problem is that when I use code below that includes client key as well at the fist enter pages shows empty google map and if I resize a little bit browser the map appears.

我不知道出什么问题了... 请帮忙.

I cannot figure out what is wrong... Any help please.

$(document).on("pagecreate", function (event) { 
			    initMap();
        });

		function initMap()
		{ 
                var map_options = {
				center: new google.maps.LatLng(-16.5112321,-68.1224865),
				zoom: 20,
				mapTypeId: google.maps.MapTypeId.ROADMAP
		        }

			  map_canvas = document.getElementById('googleMap');
			  var map = new google.maps.Map(map_canvas, map_options);
		}

推荐答案

我使用了jQuery mobile的TABS，因此解决方案是先初始化映射，然后TAB处于活动状态. 在此处找到答案#55 https://issuetracker.google.com/issues/35818323

I have used TABS of jQuery mobile so solution is to init map then TAB is active. The answer #55 was found here https://issuetracker.google.com/issues/35818323

   $( "#tabs" ).on( "tabsactivate", function( event, ui ) {
                initMap();
    } );
