如何在不使用 get 、 set 方法的情况下从 as3 中的函数获取变量?
我在从函数(addText)中检索值时遇到麻烦。i 从另一个函数 onFullScreen() 调用。我不知道我该怎么做,请帮助我?这里我附上我的代码
private function addText()
{
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, ncOnStatus);
function ncOnStatus(infoObject:NetStatusEvent)
{
trace("nc: "+infoObject.info.code+" ("+infoObject.info.description+")");
if (infoObject.info.code == "NetConnection.Connect.Success")
{
initSharedObject(chatSharedObjectName);
}
}
function formatMessage(chatData:Object)
{
trace("room"+chatData.message);
number = chatData.txtalign;//i want to retrive the value of number
number.toString();
return number;
}
function syncEventHandler(ev:SyncEvent)
{
var infoObj:Object = ev.changeList;
// if first time only show last 4 messages in the list
if (lastChatId == 0)
{
lastChatId = Number(textchat_so.data["lastChatId"]) - 1;
if (lastChatId < 0)
lastChatId = 0;
}
}
function connectSharedObject(soName:String)
{
textchat_so = SharedObject.getRemote(soName, nc.uri)
// add new message to the chat box as they come in
textchat_so.addEventListener(SyncEvent.SYNC, syncEventHandler)
textchat_so.connect(nc)
}
function connectSharedObjectRes(soName:String)
{
connectSharedObject(soName)
trace(soName)
}
function initSharedObject(soName:String)
{
// initialize the shared object server side
nc.call("initSharedObject", new Responder(connectSharedObjectRes), soName)
}
}
,我使用另一个函数中的变量,但是我无法检索该值。
private function onFullScreen(event:FullScreenEvent):void
{
mediaContainer.addMediaElement(alert);
alert.alert("Error",number);// if i cannot retrive the value hnumber here
}
Hai am Getting trouble to retrive the values from function(addText).i Called from another function onFullScreen().I dont know how Can i do this,Kindly Help me?Here i attach my Code
private function addText()
{
nc = new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, ncOnStatus);
function ncOnStatus(infoObject:NetStatusEvent)
{
trace("nc: "+infoObject.info.code+" ("+infoObject.info.description+")");
if (infoObject.info.code == "NetConnection.Connect.Success")
{
initSharedObject(chatSharedObjectName);
}
}
function formatMessage(chatData:Object)
{
trace("room"+chatData.message);
number = chatData.txtalign;//i want to retrive the value of number
number.toString();
return number;
}
function syncEventHandler(ev:SyncEvent)
{
var infoObj:Object = ev.changeList;
// if first time only show last 4 messages in the list
if (lastChatId == 0)
{
lastChatId = Number(textchat_so.data["lastChatId"]) - 1;
if (lastChatId < 0)
lastChatId = 0;
}
}
function connectSharedObject(soName:String)
{
textchat_so = SharedObject.getRemote(soName, nc.uri)
// add new message to the chat box as they come in
textchat_so.addEventListener(SyncEvent.SYNC, syncEventHandler)
textchat_so.connect(nc)
}
function connectSharedObjectRes(soName:String)
{
connectSharedObject(soName)
trace(soName)
}
function initSharedObject(soName:String)
{
// initialize the shared object server side
nc.call("initSharedObject", new Responder(connectSharedObjectRes), soName)
}
}
i using the variable in another function ,but I cannot retrive the Value.
private function onFullScreen(event:FullScreenEvent):void
{
mediaContainer.addMediaElement(alert);
alert.alert("Error",number);// if i cannot retrive the value hnumber here
}

addText() 方法是异步的,这意味着您不能简单地调用它,您需要等待事件侦听器返回值。
我不确定为什么您会觉得需要包含所有这些功能,它不是很清晰,我怀疑这是必要的。您还缺少相当多的分号...
无论如何,我看不到调用 formatMessage() 方法的位置,这似乎是定义“number”变量的唯一位置。
The addText() method is asynchronous, meaning that you can't simply call it , you need to wait for the event listener to return a value.
I'm not sure why you would feel the need to enclose all these functions, it's not very legible and I doubt it's necessary. You're also missing quite a few semi colons...
In any case , I couldn't see where the formatMessage() method was called, it seems that's the only place where the "number" variable gets defined.
您可以在函数范围之外创建变量。
然后在 addText 函数中,为变量赋值:
然后在 onFullScreen 函数中,访问 num 变量:
You could create a variable outside the scope of the functions.
Then in your addText function, assign a value to the variable:
Then in your onFullScreen function, access the num variable:
