我想根据我的GPS位置数量向Google地图标记添加标签。我将数据存储在数据库中,可以在地图上添加标记,但是我无法做的是在标记内添加标记。
for(var i = 0; i < data.length; i++) {
var coords = data[i].GPSCoordinates.split(',');
var position = new google.maps.LatLng(coords[0], coords[1]);
var labels = i + 1;
addMarker(position, map, labels);
}
function addMarker(location, map, label) {
var marker = new google.maps.Marker({
position: location,
map: map,
label: label
});
}

我收到您的代码InvalidValueError: setLabel: not a string; and no text property
的JavaScript错误。分配给label
property的值必须是字符串(或MarkerLabel
匿名对象)。该代码当前正在分配一个数字。更改:
var labels = i + 1;
收件人:
var labels = ""+ (i + 1);
代码段:
function initialize() {
var map = new google.maps.Map(
document.getElementById("map_canvas"), {
center: new google.maps.LatLng(37.4419, -122.1660756),
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var data = [{GPSCoordinates: "37.4419, -122.1419"},
{GPSCoordinates: "37.4529598, -122.1817252"},
{GPSCoordinates: "37.4335499, -122.2030209"},
{GPSCoordinates: "37.424106, -122.1660756"}
]
for (var i = 0; i < data.length; i++) {
var coords = data[i].GPSCoordinates.split(',');
var position = new google.maps.LatLng(coords[0], coords[1]);
var labels = "" + (i + 1);
addMarker(position, map, labels);
}
function addMarker(location, map, label) {
var marker = new google.maps.Marker({
position: location,
map: map,
label: label
});
}
}
google.maps.event.addDomListener(window, "load", initialize);
html,
body,
#map_canvas {
height: 100%;
width: 100%;
margin: 0px;
padding: 0px
}

在Google地图中分配给label属性的值必须是字符串。在您的代码中,它当前正在分配一个数字。 请使用这样的内容:
var labels = (i+1).toString()
