Accessing a variable outside of a javascript function?

Hello

I have the following and I want to access the variable outside of that function.

The code is:

[CODE]<script type=”text/javascript”>

/*
* Copyright 2010 Nicholas C. Zakas. All rights reserved.
* BSD Licensed.
*/
function CrossDomainStorage(origin, path){
this.origin = origin;
this.path = path;
this._iframe = null;
this._iframeReady = false;
this._queue = [];
this._requests = {};
this._id = 0;
}

CrossDomainStorage.prototype = {

//restore constructor
constructor: CrossDomainStorage,

//public interface methods

init: function(){

var that = this;

if (!this._iframe){
if (window.postMessage && window.JSON && window.localStorage){
this._iframe = document.createElement(“iframe”);
this._iframe.style.cssText = “position:absolute;width:1px;height:1px;left:-9999px;”;
document.body.appendChild(this._iframe);

if (window.addEventListener){
this._iframe.addEventListener(“load”, function(){ that._iframeLoaded(); }, false);
window.addEventListener(“message”, function(event){ that._handleMessage(event); }, false);
} else if (this._iframe.attachEvent){
this._iframe.attachEvent(“onload”, function(){ that._iframeLoaded(); }, false);
window.attachEvent(“onmessage”, function(event){ that._handleMessage(event); });
}
} else {
throw new Error(“Unsupported browser.”);
}
}

this._iframe.src = this.origin + this.path;

},

requestValue: function(key, callback){
var request = {
key: key,
id: ++this._id
},
data = {
request: request,
callback: callback
};

if (this._iframeReady){
this._sendRequest(data);
} else {
this._queue.push(data);
}

if (!this._iframe){
this.init();
}
},

//private methods

_sendRequest: function(data){
this._requests[data.request.id] = data;
this._iframe.contentWindow.postMessage(JSON.stringify(data.request), this.origin);
},

_iframeLoaded: function(){
this._iframeReady = true;

if (this._queue.length){
for (var i=0, len=this._queue.length; i < len; i++){
this._sendRequest(this._queue[i]);
}
this._queue = [];
}
},

_handleMessage: function(event){
if (event.origin == this.origin){
var data = JSON.parse(event.data);
this._requests[data.id].callback(data.key, data.value);
delete this._requests[data.id];
}
}

};

var remoteStorage = new CrossDomainStorage(“http://somewhere.com”, “/server.html”);
remoteStorage.requestValue(“something”, function(key, value){
alert(“The value for ‘” + key + “‘ is ‘” + value + “‘”);

});

alert (“I want to access value here! ” + value);
</script>[/CODE]

Ive tried two solutions, neither of them work:

[code]var somevar=””;
var remoteStorage = new CrossDomainStorage(“http://somewhere.com”, “/server.html”);
remoteStorage.requestValue(“something”, function(key, value){
alert(“The value for ‘” + key + “‘ is ‘” + value + “‘”);
somevar=value;
});
alert (“show somevar: ” + somevar);
alert (“I want to access value here! ” + value);[/code]

[CODE]var somevar=””;
var remoteStorage = new CrossDomainStorage(“http://somewhere.com”, “/server.html”);
somevar=remoteStorage.requestValue(“something”, function(key, value){
alert(“The value for ‘” + key + “‘ is ‘” + value + “‘”);
return value;
});
alert (“show somevar: ” + somevar);
alert (“I want to access value here! ” + value);[/CODE]

Thanks!
