Question

当我在我的网页上展开我的导航面板时，谷歌地图不会出现任何内容，它只显示为灰色。只有当我打开控制台时才会显示地图。我需要更改为我的代码，以便地图显示其标记和我编程的位置。当您将地图放置在面板外时，它可以完美地完成。如果有人可以扩展我编写的代码以帮助那将是伟大的。

HTML代码：

    <button class="accordion">Navigation</button>
        <div class="panel">
            <div id="map" style="width:60%;height:300px"></div>

            </div>

CSS Code:
button.accordion {
            background-color: #eee;
            color: #444;
            cursor: pointer;
            padding: 18px;
            width: 100%;
            border: none;
            text-align: left;
            outline: none;
            font-size: 15px;
            transition: 0.4s;
        }

        button.accordion.active, button.accordion:hover {
            background-color: #ddd;
        }

        div.panel {
            padding: 0 18px;
            display: none;
            background-color: white;
        }

        div.panel.show {
            display: block;
        }

脚本代码：

<script>
        var acc = document.getElementsByClassName("accordion");
        var i;

        for (i = 0; i < acc.length; i++) {
            acc[i].onclick = function(){
                this.classList.toggle("active");
                this.nextElementSibling.classList.toggle("show");
            }
        }
    </script>


    <script>
        function myMap() {
            var mapCanvas = document.getElementById("map");
            var myCenter = new google.maps.LatLng(51.508742,-0.120850);
            var mapOptions = {center: myCenter, zoom: 15};
            var map = new google.maps.Map(mapCanvas,mapOptions);
            var marker = new google.maps.Marker({
                position: myCenter,
                icon: "poi.png"
            });
            marker.setMap(map);
        }


        </script>
        <script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyB37us778WYnwNjHftUm3oL2oduV_WOt_E&callback=myMap"></script>

您的手风琴演出处理程序需要触发地图调整大小：

google.maps.event.trigger(map, "resize");

第一个脚本块的代码变为：

<script>
    var acc = document.getElementsByClassName("accordion");
    var i;

    for (i = 0; i < acc.length; i++) {
        acc[i].onclick = function(){
            this.classList.toggle("active");
            this.nextElementSibling.classList.toggle("show");
            google.maps.event.trigger(map, "resize");  //added
        }
    }
</script>
