[AS3]as3与php程序结合实现发送邮件的功能，首先在属性中绑定 Main 类

package 
{ 
    import flash.display.*; 
    import flash.events.*; 
    import flash.text.*; 
    import flash.net.*;

            form_mc.send_btn.addEventListener(MouseEvent.MOUSE_DOWN,checkFields); 
        } 
         
        private function checkFields(evt:MouseEvent):void 
        { 
            if(form_mc.name_txt.text!=""&&form_mc.email_txt.text!=""&&form_mc.message_txt.text!="") 
                sendMessage(); 
        }
