谷歌地图点击标记通过外部链接 [英] Google Map click marker by external link

问题描述

我有一些锚按钮，例如.location1、location2 等.我想在单击它们各自的按钮时突出显示位置详细信息.例如.location1 应在谷歌地图上突出显示 location1.

I have some anchor buttons eg. location1, location2, etc. I want to highlight the location details on click of their respective buttons. Eg. location1 should highlight location1 on google map.

google.maps.event.addListener(marker, 'click', (function(marker, i) {
        
        return function() {
          infowindow.setContent(locations[i][0]);
          infowindow.open(map, marker);
          map.setZoom(9);
          map.setCenter(marker.getPosition());  
        }
      })(marker, i));

function triggerClick(i) {
    google.maps.event.trigger(markers[i],'click');
}

<ul class="nav">
<li><a href="javascript:triggerClick(0)">location1</a></li>
<li><a href="javascript:triggerClick(1)">location2</a></li>
<li><a href="javascript:triggerClick(2)">location3</a></li>
<li><a href="javascript:triggerClick(3)">location4</a></li>
</ul>

推荐答案

我得到了 javascript 错误:Uncaught ReferenceError: triggerClick is not defined in your fiddle.triggerClick 函数是 onLoad 函数的本地函数，它需要是全局的才能在 HTML 点击函数中使用.

I get the javascript error: Uncaught ReferenceError: triggerClick is not defined in your fiddle. the triggerClick function is local to the onLoad function, it needs to be global to be used in an HTML click function.
