javascript - 谷歌地图调整大小 css 显示无

Question

这个问题在这里被问过很多次了，就是谷歌地图显示不全。我的问题是:我使用航点在我的页面上触发 CSS3 动画。在带有 Google map 的页面上，我将 CSS 设置为 display: none; 直到到达航路点。这会导致 Google map 崩溃。

根据我在 Stack Overflow 上的研究和搜索，修复是这样的(如果我错了请纠正我):

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

这是我从其他在线开发人员那里获得的 JavaScript 代码，我不知道将 Google map 调整大小触发器放在哪里？:

var directionDisplay;
var directionsService = new google.maps.DirectionsService();
function initialize() {
    var latlng = new google.maps.LatLng(-33.8333406,18.6470022);
    directionsDisplay = new google.maps.DirectionsRenderer();
    var myOptions = {
        zoom: 8,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        mapTypeControl: false
    };
    var map = new google.maps.Map(document.getElementById("map"),myOptions);

    directionsDisplay.setMap(map);
    directionsDisplay.setPanel(document.getElementById("directionsPanel"));
    var marker = new google.maps.Marker({
        position: latlng, 
        map: map, 
        title:"Get Directions"
    }); 
}
function calcRoute() {
    var start = document.getElementById("routeStart").value;
    var end = "-33.8333406,18.6470022";
    var request = {
        origin:start,
        destination:end,
        travelMode: google.maps.DirectionsTravelMode.DRIVING
    };
    directionsService.route(request, function(response, status) {
        if (status == google.maps.DirectionsStatus.OK) {
            directionsDisplay.setDirections(response);
        } else {
            if (status == 'ZERO_RESULTS') {
                alert('No route could be found between the origin and destination.');
            } else if (status == 'UNKNOWN_ERROR') {
                alert('A directions request could not be processed due to a server error. The request may succeed if you try again.');
            } else if (status == 'REQUEST_DENIED') {
                alert('This webpage is not allowed to use the directions service.');
            } else if (status == 'OVER_QUERY_LIMIT') {
                alert('The webpage has gone over the requests limit in too short a period of time.');
            } else if (status == 'NOT_FOUND') {
                alert('At least one of the origin, destination, or waypoints could not be geocoded.');
            } else if (status == 'INVALID_REQUEST') {
                alert('The DirectionsRequest provided was invalid.');                   
            } else {
                alert("There was an unknown error in your request. Requeststatus: \n\n"+status);
            }
        }
    });
}

这是触发显示的路点 jquery 代码: block

// Studio Page
jQuery('.studio-page').waypoint(function() {
jQuery('.kickass-studio').addClass( 'show animated bounceInLeft' );
jQuery('.location').addClass( 'show animated bounceInRight' );
jQuery('.geo-address').addClass( 'show animated bounceInDown' );

},
{
offset: '10%'
});

只需在初始化函数的末尾添加它.... 此外，您还需要将 map 对象保存在变量中，并在使谷歌地图的 css 显示时再次调用调整大小事件:使用此 map 对象 block
