推荐答案

您不能仅使用jQuery来做到这一点.您需要使用jQuery插件，例如 HTML 5 .请注意，目前并非所有浏览器都支持HTML 5，因此jQuery Uploadify可能是更好的选择.

You cannot do this with jQuery alone. You need to either use a jQuery plugin such as Uploadify or use HTML 5. Please note that not all browsers support HTML 5 at this time, so jQuery Uploadify may be the better choice.
