XML ファイルから Google マップにマーカーを配置しています。ただし、一部のマーカーは正確な位置 (緯度と経度) にあります。上部のマーカーをクリックして、infoWindow を開き、次のボタンを使用して、同じマーカーごとに xml データを循環させる必要があるかどうか疑問に思っていました。位置、私はこれについてどうすればよいかわかりません:

これは私の現在のjsで、マーカーを配置してinfoWindowを作成します

var customIcons = {
    been: {
        icon: 'http://labs.google.com/ridefinder/images/mm_20_blue.png',
        shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
    },
    going: {
        icon: 'http://labs.google.com/ridefinder/images/mm_20_red.png',
        shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
    }
};

function load() {
    var map = new google.maps.Map(document.getElementById("map"), {
        center: new google.maps.LatLng(47.6145, -122.3418),
        zoom: 3,
        mapTypeId: 'roadmap',
        mapTypeControl: false
    });
    var input = document.getElementById('searchTextField');
    var autocomplete = new google.maps.places.Autocomplete(input);
    autocomplete.bindTo('bounds', map);
    google.maps.event.addListener(autocomplete, 'place_changed', function () {
        infoWindow.close();
        var place = autocomplete.getPlace();
        if (place.geometry.viewport) {
            map.fitBounds(place.geometry.viewport);
        } else {
            map.setCenter(place.geometry.location);
            map.setZoom(17); 
        }
    });

    var infoWindow = new google.maps.InfoWindow;
    // Change this depending on the name of your PHP file
    downloadUrl("markers.php", function (data) {
        var xml = data.responseXML;
        var markers = xml.documentElement.getElementsByTagName("marker");
        for (var i = 0; i < markers.length; i++) {
            var name = markers[i].getAttribute("name");
            var address = markers[i].getAttribute("address");
            var customer = markers[i].getAttribute("customer");
            var type = markers[i].getAttribute("type");
            var visit_date = markers[i].getAttribute("visit_date");
            var comments = markers[i].getAttribute("comments");
            var image = markers[i].getAttribute("image");
            var point = new google.maps.LatLng(
            parseFloat(markers[i].getAttribute("lat")), parseFloat(markers[i].getAttribute("lng")));
            var html = "<div class=\"information\"><div class=\"thumb\"></div><span class=\"name\">" + name + "</span><span class=\"customer\"><b>Customer Name:</b> " + customer + "</span><br /><b>Address:</b> " + address + "<br /><span class=\"date\"><b>Visit Date:</b> " + visit_date + "</span><br /><span class=\"comments\"><img src=\"images/oq.png\" />" + comments + "<img src=\"images/cq.png\" /></span><img src=\'" + image + "'\" class=\"image\" /><div>";
            var icon = customIcons[type] || {};
            var marker = new google.maps.Marker({
                map: map,
                position: point,
                icon: icon.icon,
                shadow: icon.shadow
            });
            bindInfoWindow(marker, map, infoWindow, html);
        }
    });
}

function bindInfoWindow(marker, map, infoWindow, html) {
    google.maps.event.addListener(marker, 'click', function () {
        infoWindow.setContent(html);
        infoWindow.open(map, marker);
    });
}

function downloadUrl(url, callback) {
    var request = window.ActiveXObject ? new ActiveXObject('Microsoft.XMLHTTP') : new XMLHttpRequest;
    request.onreadystatechange = function () {
        if (request.readyState == 4) {
            request.onreadystatechange = doNothing;
            callback(request, request.status);
        }
    };
    request.open('GET', url, true);
    request.send(null);
}

function doNothing() {}
$(document).ready(function () {
    $(".date-pick").glDatePicker({
        onChange: function (target, newDate) {
            target.val(
            newDate.getFullYear() + "/" + (newDate.getMonth() + 1) + "/" + newDate.getDate());
        }
    });
});

助言がありますか？乾杯

このようにしてみてください

// these variables are global variables
 var infoWindow;
 var map;
// Change this depending on the name of your PHP file
    downloadUrl("markers.php", function (data) {
        var xml = data.responseXML;
        var markers = xml.documentElement.getElementsByTagName("marker");
        for (var i = 0; i < markers.length; i++) {
            var name = markers[i].getAttribute("name");
            var address = markers[i].getAttribute("address");
            var customer = markers[i].getAttribute("customer");
            var type = markers[i].getAttribute("type");
            var visit_date = markers[i].getAttribute("visit_date");
            var comments = markers[i].getAttribute("comments");
            var image = markers[i].getAttribute("image");
            var point = new google.maps.LatLng(
           markers[i].getAttribute("lat"),markers[i].getAttribute("lng"));
            var html = "<div class=\"information\"><div class=\"thumb\"></div><span class=\"name\">" + name + "</span><span class=\"customer\"><b>Customer Name:</b> " + customer + "</span><br /><b>Address:</b> " + address + "<br /><span class=\"date\"><b>Visit Date:</b> " + visit_date + "</span><br /><span class=\"comments\"><img src=\"images/oq.png\" />" + comments + "<img src=\"images/cq.png\" /></span><img src=\'" + image + "'\" class=\"image\" /><div>";
            var icon = customIcons[type] || {};
            var marker = new google.maps.Marker({
                map: map,
                position: point,
                icon: icon.icon,
                shadow: icon.shadow
            });
            bindInfoWindow(marker,   html);
        }
    });
}


function bindInfoWindow(marker,  html) {

    google.maps.event.addListener(marker, 'click', function () {


             if (infowindow) {

                infowindow.close();
            }

      infowindow = new google.maps.InfoWindow(
                        {
                            content: html                             

                        });

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