<body>
<div id="idiv">
<input class="myButton" style="left: 10px; width:auto; height:auto; visibility: visible;z-index: -0; width: auto" value="RELOAD PAGE" onclick="window.location.reload()"/>
</div>
<div style="top:100px;height: auto; width:auto;">
<?php
echo "<iframe id= \"iframe_main\" src=\"http://google.com/\"></iframe>";
?>
</div>
</body>
</html>
当我将此文档上传到我的网络服务器时，iframe 不加载 google，它想加载 iframe 源作为相对目标，而不是加载 google.com.. 如果我想加载 iframe 窗口，我需要做什么来自不同的域？
谢谢
【问题讨论】：
-
为什么要用echo，你那里的纯html页面？
-
我将从 mysqli 数据库加载（稍后）iframe 源
