当用户点击链接时,会将其重定向到某个页面,例如:
www.domain.com/index.php?var=string
在AS3中可以获取变量(var)吗?
(我知道有很多方法可以获得变量,例如,php $ _GET,但我的网站纯粹基于flash,我不想使用php获取值并将其存储在会话中并将其传递给其他页面。我无法以表格形式存储并将其传递给其他页面,因为主按钮位于Flash中,因此我需要使用AS3传递变量。)

import flash.external.ExternalInterface;
var urlStr:String = ExternalInterface.call('window.location.href.toString');
此调用要求JS为您提供当前页面网址。
然后,您可以解析它以提取变量。 http://manfred.dschini.org/2008/05/12/as3-url-class/上的示例。

使用FlashVars作为<object>
代码中的参数,查看this tutorial。基本上,您可以使用PHP或Javascript从地址字符串中获取变量,然后将它们插入到<param>
FlashVars标记中。

我是第二个@Daniels。您可以使用此类来解析字符串并将其放在易于调用的对象中。
package
{
import flash.external.*;
public class QueryString
{
private var _queryString:String;
private var _all:String;
private var _params:Object;
public function QueryString(url:String='')
{
readQueryString(url);
}
public function get getQueryString():String
{
return _queryString;
}
public function get url():String
{
return _all;
}
public function get parameters():Object
{
return _params;
}
private function readQueryString(url:String=''):void
{
_params = new Object();
try
{
_all = (url.length > 0) ? url : ExternalInterface.call("window.location.href.toString");
_queryString = (url.length > 0) ? url.split("?")[1] : ExternalInterface.call("window.location.search.substring", 1);
if(_queryString)
{
var allParams:Array = _queryString.split('&');
//var length:uint = params.length;
for(var i:int=0, index=-1; i < allParams.length; i++)
{
var keyValuePair:String = allParams[i];
if((index = keyValuePair.indexOf("=")) > 0)
{
var paramKey:String = keyValuePair.substring(0,index);
var paramValue:String = keyValuePair.substring(index+1);
_params[paramKey] = paramValue;
}
}
}
}
catch(e:Error)
{
trace("Some error occured. ExternalInterface doesn't work in Standalone player.");
}
}
}
}
然后
var myPath:QueryString = new QueryString("http://www.studiosedition.com/?page=articles");
trace(myPath.parameters.page);

这是我用来将GET查询字符串传递给我的AS3。
首先,这是主要时间轴中从PHP收集FlashVars的行为(来自developphp.com的修改代码):
// Claim the offset Number that spaces the text
// fields so they are not right on top of each other
var offSet:Number = 18;
// Claim keyStr variable as a string
var keyStr:String;
// Claim valueStr variable as a string
var valueStr:String;
// Create the paramObj Object and set it to load parameters
// from the root level being sent in by FlashVars externally
var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
// Set Text Format Object, its attributes and values
var format:TextFormat = new TextFormat();
format.font = "Verdana";
format.size = 15;
// Create the loop that iterates over all of the variables you send in using FlashVars
var i=0;
for (keyStr in paramObj) {
i++;
valueStr = String(paramObj[keyStr]); // This line gets the values of each variable sent in
var myText:TextField = new TextField(); // Create a text field to read and access each var
myText.defaultTextFormat = format; // Set the formatting into the text field properties
myText.text = keyStr + " value is: " + valueStr; // Use the vars here, I place into text field waiting
myText.y = offSet*i; // Before we place each text field on stage we offSet it
myText.width = 380; // Set the width of the text field
this.addChild(myText); // Now this line actually places the text field on stage
}
然后这是PHP(也是从developphp.com修改)
<?php
$vars = http_build_query($_GET);
?>

http_build_query($ _ GET)是一种将URL查询字符串转换回查询字符串以供Flash使用的便捷方法。
我更喜欢这种方法,因为它不需要任何黑客攻击或导入类来完成这个简单的任务。

这就是你需要的。
private function getParams():URLVariables
{
var url:String = ExternalInterface.call('window.location.href.toString');
var parts:Array = url.split("?");
if(parts.length == 2)
{
var uv:URLVariables = new URLVariables(parts[1]);
return uv;
}
else
{
return null;
}
}
在你的例子中使用(www.domain.com/index.php?var=string)写:
var params:URLVariables = getParams();
trace(params.var); // traces string
