Question

我想创建一个flash应用程序，它随机选择并在四个变量之间给它一个值。所以我写了这段代码：

import flash.events.Event;

var max:int = 100;
var red:int = 0;
var yellow:int = 0;
var orange:int = 0;
var blue:int = 0;

function updateChart():void
{
var total:int = red + yellow + orange + blue;
redbar.height = red / total * max;
yellowbar.height = yellow / total * max;
orangebar.height = orange / total * max;
bluebar.height = blue / total * max;

redres_txt.text = String(red);
yellowres_txt.text = String(yellow);
orangeres_txt.text = String(orange);
blueres_txt.text = String(blue);
total_txt.text = "Total: " + String(total);
} 
Vote_Button.addEventListener(MouseEvent.CLICK, onRedClick);
function onRedClick(evt:MouseEvent):void
{
var randomSelector:Array = [red, yellow, orange, blue];
var random:* = randomSelector[Math.floor(randomSelector.length * Math.random())];
random++;
updateChart();
}

这是整个代码。问题是;当我点击按钮时，数字返回零，其他点击不会影响。如果你想看看fla文件就在这里： https://drive.google.com/file/d/0B2f6Y60ccirBamt1RThKV2VqSjg/edit?usp=sharing

感谢。

像这样更改onRedClick处理程序：

function onRedClick(evt:MouseEvent):void
{
  var randomSelector:Array = ["red", "yellow", "orange", "blue"];
  var random:String = randomSelector[randomSelector.length * Math.random() | 0];
  this[random]++;
  updateChart();
}

随机选择变量并给它们一个值AS3
