Question

我正在尝试创建一个Google地图，其中我有多个地图标记。然后应根据这些标记的最终位置使地图居中。为了测试目的，我对一些坐标进行了硬编码。我已经为我的map-canvas div设置了高度和宽度。我无法让地图显示在页面上。我到处寻找并看过很多例子，我看起来很像例子。是的，我确实在我的实际代码中包含了我的API密钥。

            for(i = 0; i < locations.length; i++) {             
                //Edit map marker
                mapMarker = new google.maps.Marker({

                bounds.extend(mapMarker.position);

                google.maps.event.addListener(marker, 'click', (function(mapMarker, i) {
                    return function() {
                        infowindow.setContent(locations[i][0]);
                        infowindow.open(map, mapMarker);

            }

            //now fit the map to the newly inclusive bounds
            map.fitBounds(bounds);

            //(optional) restore the zoom level after the map is done scaling

这是我的styles.css页面。

    html

}

body 
{ 
    height: 100%; 
    margin: 0; 
    padding: 0;
    background-color: #b0c4de;
}

h1
{
    text-align: center;
}

#map-canvas 
{ 
    height: 75%; 
    width: 75%; 
    margin-left: auto; 
    margin-right: auto
}

#login-links
{
    text-align: right;
}

提前感谢您的帮助！

Answer 1

这是一个问题：

var infowindow = new.google.maps.InfoWindow();

应该是

var infowindow = new google.maps.InfoWindow();

另一个问题是：

 google.maps.event.addListener(marker, 'click', (function(mapMarker, i) {

应该是：

 google.maps.event.addListener(mapMarker, 'click', (function(mapMarker, i) {

无法让Google API地图显示在Javascript中
