我有各种食品类别页面(例如“碳水化合物”、“肉类”、“蔬菜”等),每个页面上有 3 个组合框,用户可以从每个类别中选择 3 种不同的成分(即在“肉类”页面上,一个用户可以选择 3 种不同类型的肉)。我将这 3 个肉类作为数组写入 sharedObject,如下所示:
这是我的saveMeat()
函数作为示例,因此您可以了解我是如何形成数组的:
function saveMeat(event:MouseEvent):void
{
_categoryMeat.btn_goback.removeEventListener(MouseEvent.CLICK, saveMeat);
removeChild(_categoryMeat);
if (meatDisableCheckBox.selected == true)
{
stop();
}
if (myComboBoxMeat.selectedLabel != null)
{
so.data.meat1 = myComboBoxMeat.selectedLabel;
trace(so.data.meat1);
}
if (myComboBoxMeat2.selectedLabel != null)
{
so.data.meat2 = myComboBoxMeat2.selectedLabel;
trace(so.data.meat2);
}
if (myComboBoxMeat3.selectedLabel != null)
{
so.data.meat3 = myComboBoxMeat3.selectedLabel;
trace(so.data.meat3);
}
var meat_items_array:Array = new Array(so.data.meat1, so.data.meat2, so.data.meat3);
so.data.meatItems = meat_items_array;
so.flush();
trace(so.data.meatItems);
}
每个类别页面都有几个这样的功能(在所有 6 个不同的功能中)。除了复选框和组合框不同之外,它们都非常相似。
我有一个名为 list 的函数dataLoaded
,它将 sharedObject 中的项目加载到滚动列表中:
private function dataLoaded():void
{
var i:Number;
for (i=0; i < so.data.meatItems.length; i++) {
_item = new Item();
// creates the var itemTextField //
_itemTextField = new TextField();
_itemTextField.text += '' + so.data.meatItems[i].toString();
//adds textfield to displaylist//
_item.addChild(_itemTextField);
}
}
如您所见,for
循环将我的 sharedObject ( ) 的toString()
属性之一的表示输入到 中,但我想输入我的 sharedObject 内的所有实例,无论它们具有什么子属性。另请注意,当我想评估循环中的所有项目时,我正在评估循环条件中的数组so.data.meatItems
TextField
length
meatItems
for
sharedObject
我怎样才能做到这一点?
编辑:我实施了以下解决方案,但收到此错误:
TypeError: Error #1010: A term is undefined and has no properties.

这是我实现以下内容的尝试(这次我已经包含了我的全部功能,以防万一我的功能中有其他东西导致问题)
private function dataLoaded():void
{
// parsing of each ingredient//
// instantiation of mcItem (the stage for each item)
for (var item:* in so.data)
{
if (so.data[item] !=null)
{
if (so.data[item] is Array)
{
var a:Array = so.data[item];
for (var i:uint = 0 ; i < a.length;i++ )
{
_item = new Item();
// sets //over// layer to invisible / transparent //
_item.item_btn_over.alpha = 0;
// creates the var itemTextField //
_itemTextField = new TextField();
// _itemTextField visual attributes //
_itemTextField.x = _textFieldXPosition + _textFieldPaddingLeft;
_itemTextField.y = _textFieldYPosition;
_itemTextField.selectable = true;
_itemTextField.wordWrap = true;
itemTextField.width = _textFieldWidth;
_itemTextField.height = _textFieldHeight;
_itemTextField.embedFonts = true;
_defaultFormat.color = 0x111112;
_defaultFormat.font = _arialRounded.fontName;
_defaultFormat.size = 18;
_itemTextField.defaultTextFormat = _defaultFormat;
_itemTextField.appendText( so.data[item][i].toString() );
//adds textfield to displaylist//
_item.addChild(_itemTextField);
//vertical positioning//
_item.y = i * _itemPosition;
_item.btn_delete.visible = false;
_item.buttonMode = true;
_item.mouseChildren = false;
//adds items to container displaylist//
_container.addChild(_item);
}
}
}
}
// Input Mask//
_mask = new Shape();
_mask.graphics.beginFill(0xFF0000);
_mask.graphics.drawRect(0, 0, _maskWidth, _maskHeight);
_mask.graphics.endFill();
// Positioning of input mask//
// horizontal centering of input mask//
_mask.x = stage.stageWidth / 2 - _container.width / 2;
_mask.y = _paddingTop;
// adds the mask onto the stage//
addChild(_mask);
// assigns the above mask to the container //
_container.mask = _mask;
// Positioning of container with the mask//
// horizontal centering of container //
_container.x = stage.stageWidth / 2 - _container.width / 2;
// vertical position of container //
_container.y = _paddingTop;
//Container background stylings//
_background = new Shape();
_background.graphics.drawRect(0, 0, _container.width, _container.height);
_container.addChildAt(_background, 0);
//End of container background stylings//
_item.parent.addEventListener( MouseEvent.CLICK, itemClicked );
_container.addEventListener(MouseEvent.MOUSE_OVER, movingOver);
_container.addEventListener(MouseEvent.MOUSE_OUT, movingOut);
}
(我尝试添加额外if
的内容来评估每个共享对象属性的内容是否为空 - 因为我相信如果数组为空,这可能会导致另一个错误?)
