ArgumentError: 错误 #2025: 提供的 DisplayObject 必须是调用者错误的子级 - AS
我在一个函数中包含以下代码片段，该函数检查舞台上是否存在对象并将其删除：
public function closeContent(e:MouseEvent):void {
removeChild(txt);
removeChild(ldr.content);
removeChild(_closeButton);
container_mc.visible = false;
statusText.text="";
if (contains(submitButton)) {
removeChild(submitButton);
}
if (contains(saveinfoButton)) {
removeChild(saveinfoButton);
}
}
我尝试使用 this 和 root 更改 stage但总是收到此错误ArgumentError：错误#2025：提供的 DisplayObject 必须是调用者的子级
I have this code snippet inside a function that checks if an object exists on stage and removes it:
public function closeContent(e:MouseEvent):void {
removeChild(txt);
removeChild(ldr.content);
removeChild(_closeButton);
container_mc.visible = false;
statusText.text="";
if (contains(submitButton)) {
removeChild(submitButton);
}
if (contains(saveinfoButton)) {
removeChild(saveinfoButton);
}
}
I tried to change stage with this and root but always get this error ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller

该错误表明您正在尝试使用
removeChild删除DisplayObject，但该DisplayObject显然不是执行此代码的DisplayObjectContainer的子级。解决此问题的一种方法是使用
contains检查您尝试删除的对象是否实际上是容器的子对象。您正在对要删除的某些对象（submitButton和saveinfoButton）执行此操作，但不会对其他对象执行此操作。尝试将
txt、ldr.content和_closeButton的removeChild调用包装在使用contains 的 if 语句中检查这些DisplayObject是否在容器中。The error signals that you are trying to remove a
DisplayObjectwithremoveChildthat apparently is not a child of theDisplayObjectContainerthis code is executed from.One way to solve this problem is to check if the object you are trying to remove is actually a child of the container using
contains. You are doing this for some of the objects you are removing (submitButtonandsaveinfoButton), but not for some others.Try wrapping the
removeChildcalls fortxt,ldr.contentand_closeButtonin if statements that usecontainsto check whether theseDisplayObjects are in the container.尝试使用：
Try with:
试试这个：
您可以使用 && 在条件中添加要删除的两项：
Try this:
You may be able to add both items for removal in the conditional with &&:
