Question

我正在尝试将addListeners分配给有多个标记且不起作用的单个标记。发生的事情是，即使我没有点击，所有窗口都会立即打开。当我点击时，没有任何反应。有什么问题？

这是我的代码：

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?key=AIzaSyDUE08r9kD1p5QsqOzmI6_EcoUNCJntf5I&sensor=false"></script>
<script type="text/javascript">

    //start the map. code from google maps tutorial.
    function initialize() { 
        var mapOptions = {
          center: new google.maps.LatLng(37.7750, -122.4183),
          zoom: 11,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        };

        //return a map for later use
        return new google.maps.Map(document.getElementById("map_canvas"),
            mapOptions); 
    }

    function request() {
        $.ajax ({
            type: "GET",
            dataType: "json",
            url: "stations.php",
            data: {
                route: $("#route").val()
            },
            success: function(data) {
                var routePathCoords = [];
                var pathColor = data.color; 

                $.each(data.stations, function(i,j) {
                    routePathCoords.push(new google.maps.LatLng(data.lat[i], data.longit[i]));

                });

                //create new map
                var map = initialize();

                //generating the polyline
                var routePath = new google.maps.Polyline({

                routePath.setMap(map);

                $.each(routePathCoords, function(i,c) {

Answer 1

您正在执行stnWindow功能而不是分配它。

你可以通过返回一个只包含ajax调用的函数来解决它，如下所示：

function stnWindow (name, marker, map) {
  return function () {
    $.ajax() //...
  }
}

在触发点击之前，不会触发返回的功能。

Try to replace :   
 google.maps.event.addListener(marker, 'click', stnWindow(name, marker, map));  
by :  
 google.maps.event.addListener(marker, 'click', function(){  
  $.ajax({  
        type: "GET",  
        dataType: "json",  
        url: "window.php",  
        data: {  
            name: name  
        },  
        success: function(data) {  
            //initializing variables for window+content  
            var station = data.fullname;  
            ....
            infoWindow.open(map, marker);
        }  
    })  
});

addListener不使用多个标记
