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);
