c# webBrowser控件与js的交互
知识：
- [System.Runtime.InteropServices.ComVisibleAttribute(true)]
- 这是为了将该类设置为com可访问
- Url属性：WebBrowser控件显示的网页路径
- ObjectForScripting属性：该对象可由显示在WebBrowser控件中的网页所包含的脚本代码访问
- JavaScript通过window.external调用C#公开的方法。即由ObjectForScripting属性设置的类的实例中所包含的公共方法。
- // WebBrowser控件显示的网页路径
- webBrowser1.Navigate(new Uri(System.Environment.CurrentDirectory + @"/XXX.html", UriKind.RelativeOrAbsolute));
- // 将当前类设置为可由脚本访问
- webBrowser1.ObjectForScripting = this;

如果需要在运行时点击按钮后再将值传入页面显示，则用下列方法传值
this.webBrowser1.InvokeScript("js中的函数"，“要传的值”);
