【问题描述】:
在我的代码中,首先,我试图通过 Google 地图上的 GeoLocation 服务找到用户的位置。
其次,我试图在用户位置附近使用 Google 的 Places Service 显示“酒吧”,例如您去喝酒的地方。它应该在用户位置附近的“酒吧”上放置标记。
但是这不起作用,我遇到了问题。但我不知道它是什么。它会在我的位置附近打开没有“酒吧”的地图。
我的css代码:
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#map_canvas {
height: 100%;
}
@media print {
html, body {
height: auto;
}
#map_canvas {
height: 650px;
}
}
这是我的 javascript 和我的 HTML 代码=

你真的需要接受那些对你之前的问题的正确答案。

好的,我接受这就是我纠正并重做的原因。
