我在将Google地图添加到我的项目时遇到了一些问题。当我得到它的身体标签它工作。但是当我有这样的结构
I have some problem with adding Google Maps to my project. When i get it into body tags it works. But when I have structure like this
<body onload="initialize()"> <div> <div id="map_canvas" style="width:100%; height:100%"></div> </div> </body>它不显示任何内容。如何解决这个问题？
it doesn't show anything. How I can solve this problem?
推荐答案这是因为 height：100％; 是始终相对于父级的高度。在你的情况下，这是无名的div，它的高度为零，因此 #map_canvas 将是它的100％，它仍然为零。因此，Google地图不会显示，因为div没有可见的高度。
It is because height: 100%; is always relative to the parent's height. In your case, this is the nameless div, which has zero height, so #map_canvas will be the 100% of that, which is still zero. So the Google Maps won't show because the div has no visible height.
如果您指定100％的父div，它将再次工作。我猜你已经有 html，body {height：100％;
If you specifiy 100% on the parent div, it will work again. I guess you already have html, body { height: 100%; } if it works being simply in the body tag.
