Question

我没有JavaScript或jQuery知识，我不知道如何使用此Google地图代码。

我需要触发此Google地图调整大小代码：

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

在下面触发此航路点后，需要触发上面的调整大小代码：

// 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%'
});

上面的代码是waypoints.js。我的问题是谷歌地图中断（你只能看到地图的左上角）。但是根据我在Stack Overflow和其他论坛上发现的内容，这是因为在我的waypoints插件完成之后div正从display: none转到display: block（添加类“show”）。因此，我需要在添加这些类的航点完成后触发Google地图调整大小。

我将如何做到这一点？

编辑：

我试过这个：

// 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' );
var currCenter = map.getCenter();
    google.maps.event.trigger(map, 'resize');
    map.setCenter(currCenter);
},
{
offset: '10%'
});

但是将上面调整大小的触发器放在那里会将Google地图从我的标记所在的长和中心点抛出？

这是我的地图脚本：

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);
            }
        }
    });
}

在调整大小后使用这些行来集中谷歌地图：

var currCenter = map.getCenter();
google.maps.event.trigger(map, 'resize');
map.setCenter(currCenter);

触发Google地图调整大小
