在我的代碼中,首先,我試圖通過Google地圖上的GeoLocation服務來查找用戶的位置。我無法獲取Google的Places服務的輸出
第二,我試圖在谷歌的地方服務附近用戶位置顯示'酒吧',就像你去喝酒的地方一樣。它應該在用戶位置附近的「酒吧」上放置標記。
但是這不起作用,我遇到了一個問題。但我不知道它是什麼。它會在我的位置附近打開沒有「酒吧」的地圖。
我的CSS代碼:
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#map_canvas {
height: 100%;
}
@media print {
html, body {
height: auto;
}
#map_canvas {
height: 650px;
}
}
這是我的JavaScript和我的HTML代碼=

您確實需要接受對以前問題的正確答案。 – Joe
好的我接受這就是爲什麼我糾正並重做它。 – user552828
