Question

如何为每个地图标记点击调用单独的函数？

对于我的例子，我尝试在点击时滚动到div，但它总是带我到最后一个地图标记的div。当我点击单独的地图标记时，如何滚动到单独的div，或者当有多个地图标记时，是否有可能在地图标记点击上触发单独的功能？

正在进行的实验 - http://nayague.com/development/tour/multiple-map-click.html

from django import template

register = template.Library()

@register.simple_tag
def multiply_by_two(value):
    return float(value) * 2.0

您的marker变量需要关闭功能。（问题解决了类似的问题：InfoWindows的Google Maps JS API v3 - Simple Multiple Marker Example，使用IIFE）。

// function closure on marker variable for the click event
google.maps.event.addListener(marker, 'click', (function(marker) {
  return function(evt) {
    console.log('click');
    var elem = $(marker.url);
    console.log(elem);

    $('html, body').animate({
      scrollTop: elem.offset().top
    }, 1000);
  }
}(marker)))

  // Display multiple markers on a map
  var infoWindow = new google.maps.InfoWindow(),
    marker, i;
  // Loop through our array of markers & place each one on the map  
  for (i = 0; i < markers.length; i++) {
    var position = new google.maps.LatLng(markers[i][1], markers[i][2]);
    bounds.extend(position);
    marker = new google.maps.Marker({
      position: position,
      map: map,
      title: markers[i][0],
      url: markers[i][3]

    // function closure on marker variable for the click event
    google.maps.event.addListener(marker, 'click', (function(marker) {

    }(marker)))
    // Automatically center the map fitting all markers on the screen
    map.fitBounds(bounds);
  }
  // Override our map zoom level once our fitBounds function runs (Make sure it only runs once)
  var boundsListener = google.maps.event.addListener((map), 'bounds_changed', function(event) {
    this.setZoom(8);
    google.maps.event.removeListener(boundsListener);
  });
