Question

我有一个带有markercluster的谷歌地图地图和各种要点。使用事件监听器生成如下所示的点，它会在页面加载的每一个点上消失。

function mappyfuntime() {
    var mapOptions = {
        center: new google.maps.LatLng(51.481581,-3.17909),
        zoom: 4,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("bigmap"), mapOptions);
    <?php echo prepare_javascript(); ?>
    var markers = [];
    var marker = [];
    linkto = new Array();
    for(g=0; g<LocationsArray.length; g++) {
        var latlng = new google.maps.LatLng(LocationsArray[g][0], LocationsArray[g][1]);
        marker[g] = new google.maps.Marker({'position': latlng});
        markers.push(marker[g]);
        google.maps.event.addListener(marker[g], 'click', click_handler(PermalinksArray[g]));
    }
    var markerCluster = new MarkerClusterer(map, markers);
}

mappyfuntime();
function click_handler(link) {
    alert(link);
}

但是，如果我将google.maps.event.addListener更改为以下内容，则会返回未定义的警报。

google.maps.event.addListener(marker[g], 'click', function() {
    alert(PermalinksArray[g]);
});

如果我将PermalinksArray [g]传递给函数，同样的事情就会发生。当在地图上点击相应的点时，有没有办法从数组（全局定义）中获取一条信息？

我猜Permalinks数组来自php插入？那么它不在全球范围内。尝试将php-insert放在你的javascript脚本顶部。

// set globals
var map;
var markers = [];
var PermalinksArray = ['...'];
var LocationsArray = ['...'];

function mappyfuntime() {

    // init map
    var mapOptions = {
        center: new google.maps.LatLng(51.481581,-3.17909),
        zoom: 4,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("bigmap"), mapOptions);

    // create markers        
    for(g=0; g<LocationsArray.length; g++) {

        // create new Position
        var latlng = new google.maps.LatLng(LocationsArray[g][0], LocationsArray[g][1]);
        // create new marker with position
        var marker = new google.maps.Marker({'position': latlng});
        // add event to marker
        google.maps.event.addListener(marker, 'click', function() {
            click_handler(marker, PermalinksArray[g]);
        });
        // push marker into markers array
        markers.push(marker);
    }
    var markerCluster = new MarkerClusterer(map, markers);
}

function click_handler(marker, link) {
    alert(link);
}

mappyfuntime();

我创建了一个包含2个标记的Google地图，当点击标记时，该区域的名称会显示在信息窗口中。标记中的信息通过名为cityList的全局定义数组加载。你可以在下面找到我的代码。
