在研究了各种预览方法后，作为总结，写了这个程序，跟大家一起分享。 上次写的简便无刷新文件上传系统最初的目的就是用来实现这个图片预览效果。 兼容：ie6/7/8, firefox 3.5.5 后台支持下还兼容：opera 10.10, safari 4.0.4, chrome 3.0 asp版本使用Persits.Jpeg组件缩放图片，测试请先安装该组件。 -After studying the various preview method, in summary, wrote this program to share with you. The last write simple non-refresh file upload system, the initial aim is to achieve this image preview. Compatibility: ie6/7/8, firefox 3.5.5 is also compatible with the background support: opera 10.10, safari 4.0.4, chrome 3.0 asp version of the use of Persits.Jpeg component scaling picture, testing, install this component.
