Question

继续获取Missing Key错误，基本上我在aspx页面上从隐藏列读取纬度和经度值，将它们发送到.JS文件。

function showMap(param1, param2) {
    var strURL = "ShowSegmentOnMap.aspx?string1=" + param1 + "&string2=" + param2 + "";
    var mywindow = window.open(strURL, "", "width=1200,height=800,scrollbars=1,resizable=1,top=10,left=200");
}

然后将lat long传递给第二个aspx页面，假设只是使用lat和long将Pin放在地图上。我现在已经硬编码了lat long值...只是试着把地图拿出来而没有运气

<script src="http://maps.googleapis.com/maps/api/js?key=MY_KEY"></script>
    
 <script>
     //var latValue = document.getElementById('lblsegment1');
     //var longValue = document.getElementById('lblsegment2');
        var latValue = 40.76;
        var longValue = 111.89;
        var map;
            function initMap() {
                var mapProp = {
                    center: new google.maps.LatLng(latValue, longValue),
                    zoom: 7,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                };
                var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
            }
            
     
            function loadScript() {
                var script = document.createElement("script");
                script.type = "text/javascript";
                script.src = "http://maps.googleapis.com/maps/api/js?callback=initMap";
                document.body.appendChild(script);
            }

            window.onload = loadScript;
    </script>
