flex：1120访问未定义的属性 [英] flex: 1120 access to undefined property

问题描述

我无法在图片中加入所需的效果。我是获取错误
120访问未定义的属性....指向HSlider / change。

什么是错误/解决方案？

 <？xml version =1.0encoding =utf-8？> 
 < mx：HBox top =10left =10> 
< mx：HSlider top = -  10left =100value = -  10toolTip =Rotation
 change =myImg.rotation = event.currentTarget
 liveDragging = 真 > 
< / mx：HSlider> 
< / mx：HBox> 
< mx：CheckBox label =Visiblechange =myImg.visible = event.currentTarget.selected
 selected =true/> 
  height =100top =60 left =30rotation = -  10> 
< mx：filters> 
< mx：DropShadowFilter /> 
< / mx：filters> 
< / mx：图片> 
< / mx：Application> 
  

在Hslider / Change属性中应该是

 myImg.rotation = event.currentTarget.valueOf（）或
myImg.rotation = event.currentTarget.value
  

提前致谢


解决方案

感谢您的代码。

这可能是一个复制/粘贴问题，但您发送的代码片段有一个主要问题：

图片名称是 myImg ，而在整个片段中，它被称为 myimg 。让我们知道，如果这是一个复制错字或实际的错误。

---

name = 对于你的图片应该是 id = 。当你在应用程序的其余部分引用组件时，你可以通过它没有设置的ID来完成。

 < ; mx：Image id =myImgsource ... 
  

I was trying to place some simple effects on an image using HBox using Hslider/Checkbox.

I am unable to incorporate the required effects on the image.I an getting the errors "120 access to undefined property" ....poinying to "HSlider/change".

What can be the error/solution to this?

<?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
      <mx:HBox top="10" left="10">
       <mx:HSlider top="-10" left="100" value="-10" toolTip="Rotation" 
             change="myImg.rotation=event.currentTarget"    
                            liveDragging="true">
       </mx:HSlider>
      </mx:HBox>
      <mx:CheckBox label="Visible" change="myImg.visible=event.currentTarget.selected"          
          selected="true"/>
      <mx:Image name="myImg" source="file:///C|/Users/terry/Desktop/test/myImage.jpg" 
                       height="100" top="60" left="30" rotation="-10">
           <mx:filters>
             <mx:DropShadowFilter />
        </mx:filters>
        </mx:Image>
    </mx:Application>

further in the "Hslider/Change" attribute it should be

"myImg.rotation=event.currentTarget.valueOf()" or 
"myImg.rotation=event.currentTarget.value"

Thanks in advance?

解决方案

Thanks for the code.

This might be a copy/paste issue, but the code snippet you sent has one major problem:

The Image name is myImg, whereas it's referred to as myimg throughout the snippet. Let us know if that's a copy typo, or an actual bug.

---

The name= for your Image should be id=. When you refer to the component within the rest of the application, you do so via its ID which wasn't set.

<mx:Image id="myImg" source...
