Question

我正在尝试在Chrome中实现谷歌地图，但是地理定位似乎没有起作用我还将设置更改为“允许所有网站跟踪＆＃39; 我已经从在线教程中获取了这些代码，因此我无法找到使其正常工作的方法

            if( navigator.geolocation ){
                // Call getCurrentPosition with success and failure callbacks
                navigator.geolocation.getCurrentPosition( success, fail );
            }else{
                alert("Sorry, your browser does not support geolocation services.");
            }

        var map;

           // Prepare the map options
           var mapOptions = {
                zoom: 14,

            // Create the map, and place it in the map_canvas div
            map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

            //search for schools within 1500 metres of our current location, and as a marker use school.png

Answer 1

initGeolocation（）不会在任何地方触发。

Answer 2

缺少id为map_canvas的div，并且您不会在代码中的任何位置调用initGeolocation函数。

检查here，一切正常
