Question

每次我向服务器请求获取设备的新位置并更新我的标记在地图上的位置时，我的标记都有问题，当我的车辆设备移动时，标记将跳转到新位置它的闪烁。如何避免闪烁，或者我的Marker可以顺利移动。

提前谢谢。

var map;
var marker;
var markerarray =[];

setInterval(function(){

    $.ajax({
        type: "post",
        url: "vehiclecordinates.php",
        success: function(data){

            coordinates = data.latlng;
            vehiclename = data.vehiclename;

            for (var i = 0; i < coordinates.length; i++) {

                newcoordinate = new google.maps.LatLng(coordinates[i].split(",")[0],coordinates[i].split(",")[1]);
                marker =  new MarkerWithLabel({
                     map:map,
                     labelClass: "mylabels",
                     labelStyle: {opacity: 1.0},
                     labelContent: '<div>'+ vehiclename[i]+'</div>',
                     icon:{
                         //some options here
                     },
                });

                marker.setPosition(newcoordinate);
                markerarray.push(marker);
            }
        }
    });

    setTimeout(function () {
        removeMarkers();
        delete marker;
    }, 1000);
},5000);

function removeMarkers() {
    for(var i = 0; i < markerarray.length; i++) {
        markerarray[i].setMap(null);
    }
}

如果您不希望它们闪烁，请不要删除＆＃34;他们从地图上，更新他们的位置。

var map;
var marker;
var markerarray =[];

setInterval(function(){
  $.ajax({
    type: "post",
    url: "vehiclecordinates.php",
    success: function(data){
      coordinates = data.latlng;
      vehiclename = data.vehiclename;
      for (var i = 0; i < coordinates.length; i++) {
        newcoordinate = new google.maps.LatLng(coordinates[i].split(",")[0],coordinates[i].split(",")[1]);
        if (markerarray[vehiclename[i]] && markerarray[vehiclename[i]].setPosition){
          markerarray[vehiclename[i]].setPosition(newcoordinate);
        else {
          marker =  new MarkerWithLabel({
            map:map,
            labelClass: "mylabels",
            labelStyle: {opacity: 1.0},
            labelContent: '<div>'+ vehiclename[i]+'</div>',
            icon:{
              //some options here
            }
          });
          marker.setPosition(newcoordinate);
          markerarray[vehiclename[i]] = marker;
        }
      }
    }
  });
},5000);
