AS3——navigateToURL

navigateToURL() 可以用来打开一个新的浏览器窗口，也可以用来flex和js之间的通信，比如打开一个新窗口：

 

var url:URLRequest = new URLRequest("http://www.eb163.com"); 
navigateToURL(url, "_blank");

 

 

这个函数也可以用来执行js，例如：

var url:URLRequest = new URLRequest(“javascript:window.close()”); 

 

或者：

var urlLURLRequest = new URLRequest(“javascript:myFun(para1…paran)”)

 

     myFun()函数是html页面的script部分定义的，函数参数一定要有引号！

navigateToURL(url, "_self");

 

也可以用来发送email：

 

var urlURLRequest = new URLRequest("mailto:55555@163.com");
navigateToURL(url, "_blank");
