Question

如何在Google地图中的infoWindow中显示不同的内容？我有谷歌地图和一个按钮。我用infowindow来显示内容。所以我怀疑的是，如果我将鼠标悬停在标记上它应该显示＆＃34;你好＆＃34;。但是当我点击一个按钮时它应该显示一些值（假设我已经编写了显示某些值的函数）请注意:: hovering应在infowindow中显示hello，按钮应显示一些值

                markers.push(marker);

google.maps.event.addListener(marker, 'mouseover', function() {
  infowindow.open(map,marker);

        }
        google.maps.event.addDomListener(window, 'load', initialize);

        function myClick(id){
            google.maps.event.trigger(markers[id], 'click');

<div id="googlemap" style="width: 100%; height: 500px;"></div>
<a href="#" onclick="myClick(0);">Open Info Window</a>

以上解决方案的问题是::一旦你点击按钮，信息窗口的内容就会永久改变（它应该改回＆＃34;你好＆＃34;再次盘旋） < / p>

Answer 1

如果您希望内容更改为＆＃34;您好＆＃34; on＆＃39; mouseover＆＃39;，将其更改为＆＃34; Hello＆＃34; on＆＃39; mouseover＆＃39;＆＃34;

google.maps.event.addListener(marker, 'mouseover', function() {
  infowindow.setContent("Hello");
  infowindow.open(map, marker);
});
