flash cookie的制作和使用例子详解 二

这一篇主要是介绍一下,在 flash cookie的制作和使用例子详解一 的基础上怎么使用外部的actionscript3的类也就是as文件,这里主要是看代码,具体的东西不做介绍,不明白的可以看看 flash cookie的制作和使用例子详解一: http://ylq365.iteye.com/blog/1873382

先定义一下外部的类,这里的这个类是从网上找的一个操作cookie的类,就以这个类做为例子
这个类型的代码如下,类名叫Cookie.as


package {   
       
    import flash.net.SharedObject;     
   
    public class Cookie {   
           
        private var _time:uint;   
        private var _name:String;   
        private var _so:SharedObject;   
           
        public function Cookie(name:String = "testFlashCookie", timeOut:uint=3600) {   
             _name = name;   
             _time = timeOut;   
             _so = SharedObject.getLocal(name, "/");   
         }   
           
        //清楚超时内容;   
        public function clearTimeOut():void {   
             var obj:* = _so.data.cookie;   
            if(obj == undefined){   
                return;   
             }   
            for(var key in obj){   
                if(obj[key] == undefined || obj[key].time == undefined || isTimeOut(obj[key].time)){   
                     delete obj[key];   
                 }   
             }   
             _so.data.cookie = obj;   
             _so.flush();   
         }   
           
        public function isTimeOut(time:uint):Boolean {   
             var today:Date = new Date();           
            return time + _time * 1000 < today.getTime();   
         }   
           
        //获取超时值;   
        public function getTimeOut():uint {   
            return _time;   
         }   
           
        //获取名称;   
        public function getName():String {   
            return _name;   
         }   
           
        //清除Cookie所有值;   
        public function clear():void {   
             _so.clear();   
         }   
           
        //添加Cookie值   
        public function put(key:String, value:*):void {   
             var today:Date = new Date();   
             key = "key_"+key;   
             value.time = today.getTime();   
            if(_so.data.cookie == undefined){   
                 var obj:Object = {};   
                 obj[key] = value;   
                 _so.data.cookie = obj;   
             }else{   
                 _so.data.cookie[key] = value;   
             }   
             _so.flush();   
         }   
           
           
        //删除Cookie值;   
        public function remove(key:String):void {   
            if (contains(key)) {   
                 delete _so.data.cookie["key_" + key];   
                 _so.flush();   
             }   
         }   
           
        //获取Cookie值;   
        public function get(key:String):Object{        
            return contains(key)?_so.data.cookie["key_"+key]:null;   
         }   
           
        //Cookie值是否存在;   
        public function contains(key:String):Boolean{   
             key = "key_" + key;    
            return _so.data.cookie != undefined && _so.data.cookie[key] != undefined;   
         }   
     }   
}   


然后在flash中调用,flash中的调用代码如下:

var myCookie:Cookie= new Cookie();
//导入ExternalInterface类
import flash.external.ExternalInterface;
flash.system.Security.allowDomain("http://localhost");
flash.system.Security.allowDomain("http://127.0.0.1");
//允许任何域都可以访问
flash.system.Security.allowDomain("*");

function setFC(obj:Object){
	myCookie.put("userInfo",obj);
}
function getFC():String{
	return myCookie.get("userInfo").userName;
	return myCookie.getTimeOut();
}
//允许js)调用flash中的getFC(),setFC(),setFCUserObj
ExternalInterface.addCallback("getFC",getFC); 
ExternalInterface.addCallback("setFC",setFC); 


再就是页面的代码:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="zh-CN" xml:lang="zh-CN">

		</style>
		<script type="text/javascript">
		
			function setFC(){
			var userName = document.getElementById("userName").value;
			var obj = new Object();
				obj.userName=userName;
				obj.sex="m";
				thisMovie().setFC(obj);
			}
		
			function getFC(){
				alert(thisMovie().getFC());
			}
			//搭建js与flash互通的环境
			function thisMovie() {
				if (navigator.appName.indexOf("Microsoft") != -1) {
					return window["testFC"];
				}else{
					return document["testFC"];
				}
			} 
			
		</script>
	</head>
	
	<body>
	<input type="text"  name="userName" id="userName"  value="" />
	<input type="button" onclick="setFC()" value="setFC" />
	<input type="button" onclick="getFC()" value="getFC" />
		
		<div id="flashContent">
			 <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="1" height="1" id="testFC" title="testFC" align="middle">
			 <param name="allowScriptAccess" value="always" />
			 <param name="movie" value="testFC.swf">
			 <param name="quality" value="high">
			 <param name="wmode" value="transparent" />
			 <embed src="testFC.swf" name="testFC" quality="high" allowScriptAccess="always"  swLiveConnect="true" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash"  width="1" height="1"></embed>
			</object>
	</div>
	</body>
</html>



运行上面的代码就可以看到我们希望的结果。用这样的方法,我们可以单独的写一些类出来,然后在flash里调用,代码更加结构化,更高的重用性等。
