在iframe上检测鼠标？

Question

I'd like call a function every time a user drags their mouse over an iframe (which points to a different domain). Is this possible?

Answer 1

I'm guessing you already tried setting a mouseover event on the actual iframe and it didn't work. If so, you can try wrapping the iframe inside a div and set the mouseover event on that div . This has to work. In the worst case scenario make the div a little big bigger (1-2px padding) than your iframe.

Answer 2

将文件加载到iframe中，在该文件上设置mouseover事件。
