全数段取值显示
这个叫法是自己取的，工作中用到了，这里记录一下。
private static const MAX_NUM:int = 5;private static const WEEK_DAYS:int = 7;private var _allList:Array = [....];private var _day:int;var remainder:int = this._allList.length % MAX_NUM;var result:Array;if(remainder == 0) {remainder = WEEK_DAYS;}var temp:int = remainder + Math.floor(this._day / WEEK_DAYS) * WEEK_DAYS;if((temp + MAX_NUM) >= this._allList.length) {temp = this._allList.length - MAX_NUM;}var startIndex:int = Math.max(0,temp);var endIndex:int = Math.min(MAX_NUM + this._day - 1,this._allList.length);result = this._allList.slice(startIndex,endIndex);
