谷歌地图移动标记与纬度/液化天然气从阿贾克斯成功返回的数据 [英] google maps move marker with lat/lng from ajax success returned data

问题描述

试图将标志/图上区间的纬度/长COORDS从SQL数据库。

Trying to move marker/map on interval with lat/long coords from sql db.

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);

设置新的google.maps.LatLng（14,41）的moveMarkerMap（）会移动，而returnedData在警报显示（），但moveMarkerMap使用时标记将不会移动（）

Setting the new google.maps.LatLng(14,41) in moveMarkerMap() will move it, and the returnedData shows in alert() but marker won't move when used with moveMarkerMap()

从阿贾克斯返回的字符串是正确的格式; （9.624672,7.242244），如图警报（） 所以不知道为什么它不工作。

The returned string from ajax is correct format; (9.624672,7.242244) as shown in alert() so not sure why its not working.

推荐答案

在google.maps.LatLng构造函数有两个号码的参数。这是行不通的：

The google.maps.LatLng constructor takes two numbers for arguments. This won't work:

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

您需要newCoords转换成两个数。

You need to convert newCoords into two numbers.

字符串转换为经纬度谷歌地图
