經過200次Google地圖功能，點擊事件不會觸發

Question

我使用Google Maps JavaScript API通過加載geoJSON數據在地圖上創建標記。每個功能都會創建一個標記，並且每個標記都具有一個可打開InfoWindow的Click事件。一切正常，直到我的地圖有超過200個功能。在200之後創建的功能在地圖上有一個標記，但點擊事件不會觸發。我對Google地圖很陌生，並且對將所有點擊事件開火都很有幫助。提前致謝。

我的代碼是：

Answer 1

您正在將google.maps.Marker對象放在DataLayer標記的頂部，當您單擊這些標記時，您不會收到InfoWindow（但如果將鼠標懸停在它們上面，將得到標記title）。

注意：這是一個時間的事情，一些google.maps.Marker對象是頂部和一些在下面，數量不一致。

刪除正在創建的google.maps.Marker對象。此代碼：

var marker = new google.maps.Marker({ 
    position: e.feature.getGeometry().get(), 
    title: e.feature.getProperty('name'), // set the market tilte to name property value from geoJson 
    map: map 
});
