源码介绍
实现了模拟按键与选择文件等功能,详细实现见压缩包
对于IE7及以下,可以简单的利用SendKeys.SendWait方法设置input值,当然首先要将焦点集中在该控件上,利用HtmlElement的focus方法很容易做到。具体可以看后面的代码。但是对于IE8来说,它的安全性更高,具体参看文章http://blogs.msdn.com/ie/archive/2008/07/02/ie8-security-part-v-comprehensive-protection.aspx。
对于IE8来说,file input只能模拟点击upload按钮,然后在弹出的对话框中输入文件名,然后点击确定。
