AnimateCC基础教学:随机抽取花名册,不能重复

 一.核心代码:

this.btnStartObj.addEventListener("click", switchBtn);
this.btnOkObj.addEventListener("click", oKBtn);
createjs.Ticker.addEventListener("tick", updateRandom);
var _this = this;
var nameArr = ["张三", "李四", "王五", "赵六", "郭七"];
var zhongNameArr = [];
var iZhongCount = 0;
var bPlaying = false;
var iIndex = 0;
var bOk=false;
function switchBtn() {
	bPlaying = !bPlaying;
}
function updateRandom() {
	if (iZhongCount >=5) {
		_this.txtObj.text = "抽奖已结束!";
		return;
	}
	if (bPlaying == true) {
		bOk=false;
		iIndex= parseInt(Math.random() * (5 - iZhongCount));
		_this.txtObj.text = nameArr[iIndex];
	} 
}
function oKBtn()
{
    if (bPlaying ==false&& bOk==false) {	
		zhongNameArr.push(nameArr[iIndex]);	
        nameArr.splice(iIndex,1);		
		iZhongCount+=1;
        bOk=true;		
	}
console.log(nameArr);
console.log(zhongNameArr);
}
