javascript - 谷歌地图设置中心。专注于新位置

Question

我正在使用谷歌地图并在 http://www.dentalo.se/search/stockholm 处呈现许多标记它工作正常。我想做的是当有人点击我想使用 map.SetCenter 的按钮并关注该位置时。

我有一个信息按钮

当用户点击它时，我调用了一个 JavaScript 函数并设置了中心。但是没有用。当我点击信息时，它只是变成灰色。您可以自己尝试一下，看看会发生什么 http://www.dentalo.se/search/stockholm .

function showCompany(latlong) {
    map.setCenter(latlong);
    alert(latlong);
}

这是渲染 map 的jquery代码

var p = $("#map_search");
        var position = p.position();
        $("#directionsPanel").css({top: position.top, position:'absolute'});

        var map;
        var addressField;
        var geocoder;
        $(document).ready(function () {
            if (navigator.geolocation) {
                navigator.geolocation.getCurrentPosition(ShowPosition);
            }
            else {
                x.innerHTML = "Geolocation is not supported by this browser.";
            }
            function showError(error) {
                switch (error.code) {
                    case error.PERMISSION_DENIED:
                        alert("User denied the request for Geolocation.");
                        break;
                    case error.POSITION_UNAVAILABLE:
                        alert("Location information is unavailable.");
                        break;
                    case error.TIMEOUT:
                        alert("The request to get user location timed out.");
                        break;
                    case error.UNKNOWN_ERROR:
                        alert("An unknown error occurred.");
                        break;
                }
            }
            function ShowPosition(position) {
                //begin rest call
                $("#latitude").val(position.coords.latitude);

当用户单击“信息” 按钮时，如何设置 SetCenter？

提前致谢。

Answer 1

map.setCenter(latlong);

latlong 必须是一个 google.maps.LatLng 对象，但在您的情况下，您正在将一个字符串传递给您的函数。

<button onclick="showCompany('59.3618356,18.0140273');return false;">Information</button>

所以那行不通。

改为尝试:

<button onclick="showCompany('59.3618356','18.0140273');return false;">Information</button>

和

function showCompany(lat, lng) {
    var position = new google.maps.LatLng(lat, lng);
    map.setCenter(position);
    alert(lat, lng);
}
