Flex、flash(as3)获取SWF后面的参数
写了一个例子。
先说flash as3吧，可以用root.loaderInfo.parameters
AS3类 GSPManager.as 代码：
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.text.TextField;
public class GSPManager extends Sprite
{
public function GSPManager()
{
this.addEventListener(Event.ADDED_TO_STAGE,addedToStageHandler);
}
private function addedToStageHandler(e:Event):void
{
this.removeEventListener(Event.ADDED_TO_STAGE,addedToStageHandler);
init();
}
private function init():void
{
var out_txt:TextField = new TextField();
//边框
out_txt.border = true;
//边框颜色
out_txt.borderColor = 0x80FF3300;
//大小
out_txt.width = 100;
out_txt.height = 20;
//位置
out_txt.x = (stage.stageWidth - out_txt.width)/2;
out_txt.y = (stage.stageHeight - out_txt.height)/2;
//添加到舞台
addChild(out_txt);
//获得参数对象
var param:Object = root.loaderInfo.parameters;
if (param["name"]!=null)
{
out_txt.text = param["name"] + param["num"];
trace("value:"+param["name"]);
//判断
}
else
{
out_txt.text = "null";
trace("value:null");
}
}
}
}
{
import flash.display.Sprite;
import flash.events.Event;
import flash.text.TextField;
public class GSPManager extends Sprite
{
public function GSPManager()
{
this.addEventListener(Event.ADDED_TO_STAGE,addedToStageHandler);
}
private function addedToStageHandler(e:Event):void
{
this.removeEventListener(Event.ADDED_TO_STAGE,addedToStageHandler);
init();
}
private function init():void
{
var out_txt:TextField = new TextField();
//边框
out_txt.border = true;
//边框颜色
out_txt.borderColor = 0x80FF3300;
//大小
out_txt.width = 100;
out_txt.height = 20;
//位置
out_txt.x = (stage.stageWidth - out_txt.width)/2;
out_txt.y = (stage.stageHeight - out_txt.height)/2;
//添加到舞台
addChild(out_txt);
//获得参数对象
var param:Object = root.loaderInfo.parameters;
if (param["name"]!=null)
{
out_txt.text = param["name"] + param["num"];
trace("value:"+param["name"]);
//判断
}
else
{
out_txt.text = "null";
trace("value:null");
}
}
}
}
GetSwfParam.fla 绑定的文档类为GSPManager.as ,在文档类绑定框里写GSPManager这个就可以了
之后编译出来的GetSwfParam.swf 就可以添加到页面了
Java web页面代码：
<%@ page language="java" import="java.util.*" contentType="text/html;charset=GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

这里要说的是swf后有很多参数就用&符号 , 比如GetSwfParam.swf?name=sange&num=66&id=1
现在说Flex了，因为让同事也做了这样的东西，但他只会Flex，他没弄出来，所以我试下，发现用root没反映，但我很肯定Flex应该也可以弄出来，发现跟flash as3确实不同，不能用root，因为Flex中没有root这个概念。问了群里的人，收获大了，原来就Application，哈哈，不就是根节点么，也就相当于root，就是名称不一样。
Flex就用Application.application.parameters
GetSwfParam.mxml 代码：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" backgroundColor="#ffffff" layout="absolute" creationComplete="init()">
<mx:Script>
<![CDATA[
private function init():void
{
//获得参数对象
var param:Object = Application.application.parameters;
if(param["name"] != null)
{
mytxt.text = param["name"];
}
else
{
mytxt.text = "null";
}
}
]]>
</mx:Script>
<mx:TextInput id="mytxt" x="60" y="47"/>
</mx:Application>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" backgroundColor="#ffffff" layout="absolute" creationComplete="init()">
<mx:Script>
<![CDATA[
private function init():void
{
//获得参数对象
var param:Object = Application.application.parameters;
if(param["name"] != null)
{
mytxt.text = param["name"];
}
else
{
mytxt.text = "null";
}
}
]]>
</mx:Script>
<mx:TextInput id="mytxt" x="60" y="47"/>
</mx:Application>
把编译好的swf添加到页面就可以了。同上，Java web页面代码不变。
