我有這兩個文件：AJAX谷歌地圖不加載
mappa2.html：
#map { 高度：85％; }
</style>
<script>
function showHint() {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
}
};
xmlhttp.open("GET", "sql2.php", true);
xmlhttp.send();
}
</script>

如果我加載mappa2.html，地圖不加載。但是，如果我複製生成的代碼並將其放入另一個html文件中，則地圖顯示正確。
如果我寫在JS控制檯：initMap()它說：
Uncaught ReferenceError: initMap is not defined
at <anonymous>:1:1
請刪除此問題中不需要的源代碼部分。那怎麼樣，用戶解決你的問題更有效率。 – CuriousSuperhero
