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());

}

<ul class="nav">

Answer 1

我收到你的小提琴中的javascript错误：Uncaught ReferenceError: triggerClick is not defined。 triggerClick函数是onLoad函数的本地函数，它需要是全局的才能在HTML单击函数中使用。
