关闭打开的 infowindows - google maps api

Question

我正在尝试当用户单击标记时，它会打开和关闭所有以前打开的标记。我正在尝试使用此代码，但没有运气，知道该怎么做吗？

更新了我正在使用的完整脚本并基于答案的可能解决方案：

    (function($) {

    /*
    *  new_map
    *
    *  This function will render a Google Map onto the selected jQuery element
    *
    *  @type  function

    *  @since 4.3.0
    *
    *  @param $el (jQuery element)
    *  @return  n/a
    */

    function new_map( $el ) {

      // var
      var $markers = $el.find('.marker');


      // vars
      var args = {
        scrollwheel: false,
        zoom    : 5,
        center    : new google.maps.LatLng(0, 0),
        mapTypeId : google.maps.MapTypeId.ROADMAP
      };


      // create map           
      var map = new google.maps.Map( $el[0], args);


      // add a markers reference
      map.markers = [];


      // add markers
      $markers.each(function(){

          add_marker( $(this), map );

      });


      // center map
      center_map( map );


      // return
      return map;

我对你的代码做了一点改动。

var infoWindows = [];
if( $marker.html() ){

    // Need to clear up old info windows before adding new ones
    for (var i = 0; i < infoWindows.length; i++) {
      infoWindows[i].setMap(null);
    }
  // show info window when marker is clicked
  google.maps.event.addListener(marker, 'click', function() {

  // create info window
    var infoWindow = new google.maps.InfoWindow({
      content   : $marker.html()
    });

    infoWindow.open( map, marker );
    infoWindows.push(infoWindow);
  });
}

我希望它会起作用。如果没有，请告诉我有关您的代码的更多详细信息。 谢谢
