Question

我有

var marker = new MarkerWithLabel({
            position: uav.Position,
            icon: mapStyles.uavSymbolBlack,
            labelContent: uav.Callsign + 
              '<div style="text-align: center;"><b>Alt: </b>' + uav.Alt + 
              '<br/><b>Bat: </b>' + 
              uav.Battery + '</div>',
            labelAnchor: new google.maps.Point(95, 20),
            labelClass: "labels",
            labelStyle: { opacity: 0.75 },
            zIndex: 999999,})

这个标记在我的JavaScript文件中，但是java控制台一直给我一个错误。

Uncaught ReferenceError: MarkerWithLabel is not defined

我认为MarkerWithLabel是google maps api的内置功能。但它没有用。

Answer 1

MarkerWithLabel不属于Google Maps Javascript API v3，它位于第三方库MarkerWithLabel。

一个迹象是，如果它是API的一部分，它将是google.maps.MarkerWithLabel。

var map;

function initialize() {
    map = new google.maps.Map(
    document.getElementById("map_canvas"), {
        center: new google.maps.LatLng(37.4419, -122.1419),
        zoom: 13,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    });
    var marker = new MarkerWithLabel({
        position: map.getCenter(),
        // icon: mapStyles.uavSymbolBlack,
        labelContent: "uav.Callsign" + '<div style="text-align: center;"><b>Alt: </b>' + "uav.Alt" + '<br/><b>Bat: </b>' + "uav.Battery" + '</div>',
        labelAnchor: new google.maps.Point(95, 20),
        labelClass: "labels",
        labelStyle: {
            opacity: 0.75
        },
        zIndex: 999999,
        map: map
    })
}
google.maps.event.addDomListener(window, "load", initialize);

html, body, #map_canvas {
    height: 500px;
    width: 500px;
    margin: 0px;
    padding: 0px
}
.labels {
    background-color: white;
    border-style: solid;
    border-width: 1px;
}
