無法加載Javascript

我想加載這個谷歌地圖畫布，它只是不會工作。谷歌示例工程，這表明這是一個代碼錯誤。無法加載Javascript

任何人都可以在這段代碼中看到任何錯誤？

我加入它變成一個DIV地圖畫布的DIV ID

var marker; 
    var infowindow; 

    function initialize() { 
     var latlng = new google.maps.LatLng(54.559322, -4.174804); 
     var options = { 
     zoom: 6, 
     center: latlng, 
     mapTypeId: google.maps.MapTypeId.ROADMAP 
     } 
     var map = new google.maps.Map(document.getElementById("map-canvas"), options); 
     var html = "<table>" +

可以重現錯誤與小提琴？ – karthikr

您的XML有效嗎？ – geocodezip

我用你的代碼看到一張地圖。你甚至沒有收到地圖嗎？你給了地圖 - 畫布div一個大小？ – geocodezip

你的CSS是錯誤的。該地圖不具有大小：

.map-canvas { 
     width: 400px; 
     height: 400px; 
}

應該是：

#map-canvas { 
     width: 400px; 
     height: 400px; 
}

偉大的作品！但爲什麼？ – user2932546

因爲.map-canvas不正確（你沒有類「map-canvas」的div），你確實有一個id爲「map-canvas」的div（這就是「＃」的意思）。 – geocodezip
