ArrayCollection动态增添元素，遍历

ArrayCollection动态添加元素，遍历

   

function initYearList():void{ 

   //动态添加本年度前十年

    var yearList:ArrayCollection = new ArrayCollection();

    var dt:Date=new Date();
    var curYear:Number=dt.fullYear;
    var firstItem:Object=new Object();
    firstItem.name=curYear as String;
    firstItem.value=curYear as String;
    for (var i:int=0; i < 11; i++)
    {
     var item:Object=new Object();
     var tempYear:Number=curYear - i;
     var tempYearStr:String=tempYear.toString();
     item["name"]=tempYearStr;
     item["value"]=tempYearStr;
     yearList.addItem(item);
    }

}

 

//如果下拉框某个值跟指定值相等，则选中该下拉框项

for each (var item:Object in yearList)
    {
     if (item["value"] == yearStr)
     {
      year.selectedItem=item;
     }
    }
