https://developers.google.com/maps/documentation/javascript/examples/places-searchbox需要
我使用這是我從上面的鏈接得到的地圖從谷歌地圖API獲取經緯度。它在我的網站上工作正常。當我搜索一個地方時，該地點將顯示在地圖上。我需要獲取它的經度和緯度，並且當我點擊Google地圖上的某個地方時，應該顯示在文本框中。
的代碼如下所示

我是否需要更換代碼places.forEach（函數（地方）{VAR 圖標= { url：place.icon， size：new google.maps.Size（71，71）， origin：new google.maps.Point（0，0）， anchor：new google.maps.Point（17，34）， scaledSize：new google .maps.Size（25,25）用上面的代碼？ – vyshakh
不，上面的代碼會將您正在查找的座標記錄到控制檯。您應該添加該行並保留其他所有內容。雖然如果你想要在文本框中的數據，你需要將文本框添加到HTML，然後填充它們：'document.getElementById（'latbox'）。value = place.geometry.location.lat（）;' – lucas
請考慮編輯您的帖子以添加有關您的代碼的功能的更多說明以及爲什麼它可以解決問題。一個主要包含代碼的答案（即使它正在工作）通常不會幫助OP瞭解他們的問題。 – SuperBiasedMan
