How can I prevent the page from reloading after posting a form?

Question

Normally, I'd use AJAX for this, but the purpose of the form is to upload a file, which AJAX can't do.

Is there a way to let the form submit normally, but catch the response (JSON/XML or similar) and handle it in javascript without the page refreshing/redirecting?

Answer 1

添加一个隐藏的iframe，然后使用target属性将表单发布到iframe。
