推荐答案

如果你想禁用鼠标交互，这应该可以。

If you're wanting to disable mouse interaction, this should work.

将DIV放在iframe的顶部，就像这样（用你自己的替换顶部，左边，宽度和高度值）：

Put a DIV over the top of your iframe, like so (replace top, left, width and height values with your own):

<div id="blank" style="display:none; position:absolute; top:100px; left:100px; width:600px; height:400px;">

当您要禁用iframe时，请在javascript中执行此操作：

and when you want to disable the iframe, do this in javascript:

document.getElementById("blank").style.display="block";
