javascript - 单击并移动鼠标后，谷歌地图停止工作

我有以下代码，其中有两个按钮，一个用于显示 map ，另一个用于隐藏 map 并显示段落。问题是，当我第一次打开页面时，它会显示 map ，但一旦我尝试移动它以找到选定的位置，它就会停止显示 map 。

之前(加载演示后)

之后(尝试在 map 上找到地址)

最佳答案

map 显示后需要触发“resize”事件，然后在确定大小后设置中心:

function populateMap() {
    $("#para").hide();
    $("#myMap").show();
    google.maps.event.trigger(map,'resize');
    map.setCenter(centreLoc);
}

updated fiddle

代码片段(已删除signed_in=true，在SO代码片段中效果不佳):

function hideMap() {
        $("#myMap").hide();
        $("#para").show();
    }

    function populateMap() {
        $("#para").hide();
        $("#myMap").show();
        google.maps.event.trigger(map,'resize');
        map.setCenter(centreLoc);
    }
    var map;
    var centreLoc;
    var markers = [];
    var pinColor = "FE7569";
    function pinImage(imagenum) {
        return image = new google.maps.MarkerImage(
                "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld="
                        + imagenum + "|" + pinColor);
    }

    function initialize() {
        centreLoc = new google.maps.LatLng(37.9908372,23.7383394);
        var mapOptions = {
            zoom : 13,
            center : centreLoc,
            disableDefaultUI : true,
            mapTypeControlOptions : google.maps.MapTypeId.ROADMAP
        };
        map = new google.maps.Map(document.getElementById('myMap'),
                mapOptions);
        hideMap();
        var results = [ [ 'Pos1', 37.9908372,23.7383394 ],
                [ 'Pos2', 37.89,23.7383394 ] ];
        processResults(results);
    }

    function processResults(results) {
