在infowindow.setContent我有按鈕時，我想在單擊時更改標記顏色按鈕，我嘗試了此代碼      google.maps.event.addListener(marker, 'click', (function(marker, i) {        return function() {          infowindow.setContent(locations[i][0] + locations[i][3] + " <button class='btn btn-primary btn-sm map-checked-box mr-1' onclick='myFunction();' data-id='"+ locations[i][3] +"'>Print</button> ");          infowindow.open(map, marker);        }      })(marker, i ));    }    function myFunction() {  infowindow.setContent('<div style="background-color: green">' + locations[i][0] + locations[i][3] + "</div>");} 我正在調用 myfunction() 但它在這一行中不起作用我想我在函數中定位錯誤infowindow.setContent(locations[i][0] + locations[i][3] + " <button class='btn btn-primary btn-sm map-checked-box mr-1' onclick='myFunction();' data-id='"+ locations[i][3] +"'>Print</button> ");
