今天在做uploadify上传时，发现只要一初始化就会发出一个请求，而这个请求是当前页面的地址，觉得很郁闷，然后找了很久才找到问题所在，应该也算是一个bug吧，给出解决方案
将这个代码换成下面就可以了
this.settings.upload_url = SWFUpload.completeURL(this.settings.upload_url); this.settings.button_image_url = SWFUpload.completeURL(this.settings.button_image_url)
改为
this.settings.upload_url = SWFUpload.completeURL(this.settings.upload_url); this.settings.button_image_url = this.settings.button_image_url ? SWFUpload.completeURL(this.settings.button_image_url) : this.settings.button_image_url
