从文件对话框中选择文件后，如何上传文件？

Question

I want to upload an image just after the user select it from the dialog, not using another submit button? how to do this?

Answer 1

I haven't tried, but I believe you could submit using javascript. Hook the js function to the onChange() event of the file object?

There also appears to be an input event <- this article shows how to hook the event also.

To submit the form see here
