【问题描述】：

我在 asp.net 中使用 google map 多标记，这里我需要将一个数组值从服务器端发送到客户端变量。我正在使用“ClientScript.RegisterArrayDeclaration”将数组传递给我的客户端变量。但它不起作用。请帮助我。我需要在页面加载时传递值。 “位置”是我的 java 脚本变量 *

        var geocodevalues = string.Join(",", oGeocodeList.ToArray());
        ClientScript.RegisterArrayDeclaration("locations", geocodevalues);

    }

【解决方案1】：

在您的示例中，地图被初始化之前 locations 变量在页面上被定义。一种选择是在页面加载后初始化地图：

function initMap() {

    var map = new google.maps.Map(document.getElementById('map'), {
        zoom: 8,
        center: new google.maps.LatLng(9.918648010, 78.12000),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    });
    var infowindow = new google.maps.InfoWindow();
    for (var i = 0; i < locations.length; i++) {
        var marker = new google.maps.Marker({
            position: new google.maps.LatLng(locations[i][1], locations[i][2]),
            map: map
        });
        google.maps.event.addListener(marker, 'click', (function (marker, i) {
            return function () {
                infowindow.setContent(locations[i][0]);
                infowindow.open(map, marker);
            }
        })(marker, i));
    }

}
google.maps.event.addDomListener(window, 'load', initMap);
