Question

我的应用程序在Flex 3.5中...我的代码在这里，如何获取textarea的id值？ Button.Mxml

<mx:Button width="20" height="20" label="TextArea" id="textarea" click="setShape(DrawObject.TEXT);showTextArea()"/>

我的另一个档案在这里： Main.Mxml

 private function doMouseDown_canvas():void
                    {
                            if(this.shapeStyle==DrawObject.TEXT)
                            {
                                    if(isDrawing)
                                    {
                                            isDrawing = false;
                                            this.d = drawFactory.makeDrawObject(this.shapeStyle,segment, this.drawColor, this.thickness, textarea.text);
                                            dispatchEvent(new Event(BoardMediator.SEND_SHAPE));

                                    textarea.visible = false;
                                    }else
                                    {
                                            isDrawing = true;
                                            x1 = canvas.mouseX;
                                            y1 = canvas.mouseY;
                                            segment.push(x1);
                                            segment.push(y1);

                                            textarea.text = "";
                                    textarea.visible = true;
                                            textarea.x = canvas.mouseX;
                                            textarea.y = canvas.mouseY;
                                            textarea.setFocus();

                                            locateEditor();
                                    }
                            }else
                            {
                                    isDrawing = true;
                                    x1 = canvas.mouseX;
                                    y1 = canvas.mouseY;
                                    segment.push(x1);
                                    segment.push(y1);
                                    canvas.rawChildren.addChild(feedback);
                            }
                    }

Answer 1

你必须在某个地方使用Button.mxml ......！设置mxml文件中某事物的ID，使该对象成为相应类的公共属性。

如果<mx:Button>是你的button.mxml里面唯一的东西，那就去掉button.mxml里面的ID并从外面设置它。

如果你有一个周围的容器，就像HGroup一样，你可以从你的主要访问它：

<myNS:Button id="myButton" />

并在fx:Script标记中：

myButton.textarea;
