Question

我写了一个网页，并将Google Map插入其中。但地图始终没有显示。我试图用Firebug看看发生了什么，发现没有错误。

地图画布的div已被Google Map API 正确替换但该div未显示... 我调试了几天，仍然没有解决方案。

Answer 1

您没有设置地图div的尺寸，而是设置地图嵌套的div的尺寸。将div和width属性添加到div id'map-canvas'并显示地图。

    <div id="map-canvas" style="width: 400px; height: 400px;">Loading...</div>

Answer 2

您的地图div没有大小。这个：

<div id="map-canvas" style="height:300px; width:300px;">

让它显示给我。

谷歌地图未显示
