You could try something like this jquery plugin. It's not identical to Facebook but provides controlled crop functionality.
你可以试试这个jquery plugin 之类的东西。它与 Facebook 不同，但提供受控裁剪功能。
Otherwise, the question has been answered here: Is there a jQuery image cropping plugin similar to Facebook's image crop?
否则，这里已经回答了问题：是否有类似于 Facebook 图像裁剪的 jQuery 图像裁剪插件？
EDIT: Try this one: imgareaselect.
