我想記錄標記的座標谷歌地圖。我做了一個ajax請求記錄數據，但jquery是拋出一個錯誤。我正在使用Spring MVC框架並將數據寫回到MySql數據庫。下錯誤附：Ajax請求記錄數據谷歌地圖Animate（）
animate函數
function animate(index,d) {
if (d>eol[index]) {
marker[index].setPosition(endLocation[index].latlng);
if(marker[index].getPosition() == endLocation[index].latlng){
console.log('Completed'+' '+index);
//alert("Marker One Complete");
}
return;
}
var p = polyline[index].GetPointAtDistance(d);
//map.panTo(p);
marker[index].setPosition(p);
updatePoly(index,d);
timerHandle[index] = setTimeout("animate("+index+","+(d+step)+")", tick);
//log movement
logMovement(index,marker[index]);
}
Ajax的函數Log運動
function logMovement(index,marker){
$.ajax({
type:'GET',
url:'logMovement.htm',
data:{lat:marker.getPosition().lat(),
lng:marker.getPosition().lng,
socialSecurityNumber:global_citizens[index].socialSecurityNumber},
dataType: 'json',
success:function(data){
if (data == false){
console.log('error occured in logging data');
}
}
});
}
控制器映射
@RequestMapping(value="logMovement.htm", method=RequestMethod.GET)
public void logMovement(@RequestParam double lat, double lng, int socialSecurityNumber)throws Exception{
logger.info("About to log movement");
this.markerManager.logMovement(lat, lng, socialSecurityNumber);
}

我更新了問題，幷包括整個JavaScript，如果你想看看它 – devdar
我把功能放在一個定時器10秒後執行，但這仍然沒有記錄任何座標。得到了同樣的錯誤。有沒有解決方法？ – devdar
如果您收到同樣的錯誤，則表示您已達到Google Maps API限制。看看這個：https：//developers.google.com/maps/documentation/business/articles/usage_limits#problems –
