在navigatorcontent中获取id

Question

“Stab”是一个tabnavigator，我喜欢在navigatorcontent中访问数据网格中的id。我试过getchildbyname它似乎无法找到datagrid“nc1，nc2等”并返回null。

private var pdg:String="nc";
        private function stabAdd():void {
            var dg1:DataGrid = new DataGrid();
            var cn:NavigatorContent = new NavigatorContent(); 
            stab.addElement(cn);
            cn.label = "New Tab";
            cn.name = "nct"+nu;
            cn.id = "nct"+nu;
            dg1.id = "nc"+nu;
            dg1.name = "nc"+nu;
            pdg = dg1.id;   //set this as current datagrid
            nu++;

            var columns:Array = [];
            var myDataGridColumn:DataGridColumn = new DataGridColumn("id");
            myDataGridColumn.headerText = "ID";
            myDataGridColumn.width = 40;
            columns.push(myDataGridColumn);
            myDataGridColumn = new DataGridColumn("username");
            myDataGridColumn.headerText = "Name";
            myDataGridColumn.width = 160;
            .....
            dg1.columns = columns;

            cn.addElement(dg1);
            stab.selectedIndex = stab.numChildren-1;
        }

容器只是我父母的术语..如何将所有DataGrids添加到数组中。然后您可以按ID搜索：

function findDataGrid(findID:String):DataGrid
{
    var i:DataGrid;
    for each(i in array)
    {
        if(i.id == findID) return i;
    }

    return null;
}
