Question

我的皮肤：

# edit.html.erb
<%= f.email_field :email, :required => true, :pattern => EMAIL_REGEX %>

我的创建对象'砖'视图

pattern

类DataAboutBrick用于保存有关对象的数据：

pattern="(?i-mx:\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z)"

中保：

<s:DataGroup id="view1" width="100%" height="100%" itemRenderer="views.itemRenderers.BrickItemRenderer" dataProvider="{hostComponent.createArray()}">
    <s:layout>
      <s:TileLayout /> 
    </s:layout>
  </s:DataGroup>

介质在单击对象时更改所有对象的颜色。并且只需要改变要按下的对象的颜色。

假设您已定义Brick和BrickSkin，您可以定义更改BrickItemRenderer中颜色的功能，如下所示：

<?xml version="1.0"?>

<spark:DefaultComplexItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:spark="spark.skins.spark.*">
<fx:Script><![CDATA[
    [Bindable("dataChanged")]
    override public function set data(value:Object):void
    {
        super.data = value;
        var brick:Brick = new Brick();
        brick.colorBrick = value.color;
        brick.addEventListener(MouseEvent.CLICK, brickClicked,false,0,true);
        this.addElement(brick);
    }

    private function brickClicked(event:Event)
    {
        event.stopImmediatePropagation();
        event.preventDefault();
        data.color = 0x00FF00;// Please make sure your color variable defined in DataAboutBrick.as is Bindable.
    }
    ]]></fx:Script>
</spark:DefaultComplexItemRenderer>
