1、LoadVars vs getURL
send()
getURL有很多的限制，LoadVars则弥补了这一点

Flash时间轴脚本:
System.useCodepage=true;
signBtn.onRelease=function()
{
       var formVars:LoadVars=new LoadVars();
       formVars.userName=signForm.userName.text;
       formVars.userPass=signForm.userPass.text;
       formVars.userMail=signForm.userMail.text;
       formVars.send(http://www.chinawecan.com/FlashForm.php,"_blank","GET");
}

2、sendAndLoad()
Flash:
第1帧:
System.useCodepage=true;
var yName:String="";
var yPass:String="";
var yMail:String="";
signBtn.onRelease=function()
{
       var formVars:LoadVars=new LoadVars();
       formVars.userName=signForm.userName.text;
       formVars.userPass=signForm.userPass.text;
       formVars.userMail=signForm.userMail.text;
       var resultVars:LoadVars=new LoadVars();
       resultVars.onLoad=function(success)
       {
              if(success)
              {
                     play();
                     yName=this.yourName;
                     yPass=this.yourPass;
                     yMail=this.yourMail;
              }else{
                     trace("失败");
              }
       }
       formVars.sendAndLoad("http://localhost/php/signin.php",resultVars,"GET");
}
stop();
第2帧:
stop();
yourName.text=yName;
yourPass.text=yPass;
yourMail.text=yMail;
Php:
<?php
echo "yourName=".$_GET["userName"]."&";
echo "yourPass=".$_GET["userPass"]."&";
echo "yourMail=".$_GET["userMail"];
?>
