推荐答案

您所描述的不能完毕.当用户选择图像时，您将根本无法显示该图像.为了显示图像，您需要先将其上传到您的网站.

也许您可以使用AJAX将图像上传到temp文件夹，然后如果用户决定保留它，则将其移动到其永久文件夹.

更新:有许多使用ajax/jQuery的方法.一个示例在此处 http://www.zurb.com/playground/ajax_upload [

What you describe can not be done. you simply won''t able to show the image when the user selects it. In order for the image to be displayed you need to upload it to your site first.

May be you can upload the image to temp folder using AJAX, then if the user decided to keep it move it to its permanent folder.

UPDATE: there are many ways to do it using ajax/jQuery. One example is here http://www.zurb.com/playground/ajax_upload[^]
