本文探讨了在Internet Explorer浏览器中遇到的一个常见问题：从一个框架尝试提交另一个框架内的表单时出现的安全限制。文章建议避免使用form.submit()方法，并推荐采用让用户点击提交按钮并利用表单的onsubmit事件进行验证的方式。

That's right, avoid form.submit() if you can. (And 99% of the time, you can.) IE (especially IE7) takes a lot of extra security precautions when a script in one frame tries to invoke certain actions (such as form submission) in another frame. Instead, have the user click a "submit" button and cancel (if necessary) using an "onsubmit" handler attached to the form, instead of validating and then submitting.

Although browsers can be difficult, there are many ways to get the job done. If your first approach doesn't work there are probably several others that will.
