javascript – 谷歌地图从ajax成功返回数据移动标记与lat / lng

尝试使用sql db中的lat / long coords间隔移动标记/贴图.

function initialize() {
    var myLatLng = new google.maps.LatLng(41,14);

    var myOptions = {
        zoom: 16,
        center: myLatLng,
        scrollwheel: false,
        panControl: true,
        zoomControl: true,
        mapTypeControl: true,
        scaleControl: true,
        streetViewControl: true,
        overviewMapControl: true,
        mapTypeId: google.maps.MapTypeId.SATELLITE,
    }

    map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);

    marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        draggable: false
});

}
google.maps.event.addDomListener(window, 'load', initialize);

function getCoords() {

$.ajax({
url: "../ajaxscript.PHP",
type: "POST",
data: {
foo : "bar"
},
dataType: "text",
success: function(returnedData) {
      alert(returnedData);
    moveMarkerMap(returnedData);
}
});

}

function moveMarkerMap(newCoords) {
var newLatLang = new google.maps.LatLng(newCoords);
map.panTo(newLatLang);
marker.setPosition(newLatLang);

}
window.setInterval(getCoords, 5000);

在moveMarkerMap()中设置新的google.maps.LatLng(14,41)将移动它,并返回的数据显示在alert()中但是当与moveMarkerMap()一起使用时,marker将不会移动

来自ajax的返回字符串格式正确; (9.624672,7.242244)如alert()所示
所以不确定为什么它不起作用.

解决方法:

google.maps.LatLng构造函数为参数提取两个数字.这不起作用：

var newLatLang = new google.maps.LatLng(newCoords);

您需要将newCoords转换为两个数字.

Convert String to latlng google maps

Convert “[52.43242, 4.43242]” to google LatLng

How do I get a pin on Google Maps using location from a variable?
