无法让 Google API 映射出现在 Javascript 中

Can't get Google API map to appear in Javascript

本文关键字：Javascript 映射 Google API 更新时间：2023-09-26

我正在尝试创建一个谷歌地图，其中有多个地图标记。然后，应根据这些标记的最终位置将地图居中。我已经硬编码了一些坐标以进行测试。我也已经为我的地图画布div 设置了高度和宽度。我无法让地图显示在页面上。我到处看过，看过很多例子，我的例子看起来很像这些例子。是的，我确实在我的实际代码中包含我的 API 密钥。

    <div id="map-canvas"/>

这是我的样式.css页面也是。

    html 
{ 
    height: 100%;
}
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;
}

提前感谢任何帮助！

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) {
