Question

我将以下代码放在一起，从我的SQL数据库加载标记数据，正确显示所有信息。

我现在想要包含一个下拉菜单，通过“位置名称”显示标记，当用户选择相关标记反弹的位置时。我从一些信息中得知，我发现这是一个侧边栏？或许有人可以指出我正确的方向，我将如何调整我的代码以包含这个。

Answer 1

这是一个想法：
将每个位置名称与下拉菜单中的链接相关联存储每个位置的标记当您从下拉菜单中单击链接时，检索与该位置关联的标记，然后只需调用一个为其设置动画的功能：

 ....
<!-- assuming this is an item from the menu -->
 <a href="javascript:;" title="locationName" onclick="animate(this)">Location Name </a>
 ....

剧本：

<script type="text/javascript">
function animate(element) {
   var marker = getMarkerByName(element.title);
   marker.setAnimation(google.maps.Animation.BOUNCE);
   setTimeout(function() { marker.setAnimation(null); }, 200);
}

function getMarkerByName(name) {
   // retrieve and return the marker from where you stored it
}
</script>
...

像这样的东西

基本没有变化......当您点击链接时，突出显示它并调用动画功能要在标记点击时突出显示正确的链接，请单击“标记”每个标记：

google.maps.event.addListener(marker, 'click', function(event) {
     // animate marker
     // highlight the link associated with the marker.
});

下拉菜单（边栏）
