看这错误应该是代码的removeChild()出了问题

把相关代码贴下吧~~~

[hellen6xu]

if(bj=="dash")
{ca.addChild(btn);}
else if(bj=="gh"){
cb.addChild(btn);

c.removeChild(ca);
c.addChild(cb);
}else if(bj=="hh"){
cc.addChild(btn);
if( c.contains( ca ) )
c.removeChild(cb);

[hellen6xu]

有人告诉我 用if(c.contains(ca)) 这句话就可以解决，但是我没弄明白，它的写法

[niwenbin416]

if(bj=="dash"){
  ca.addChild(btn);
}
else if(bj=="gh"){
  cb.addChild(btn);
}
if( c.contains( ca ) ){  
   c.removeChild(ca);
}
  c.addChild(cb);  
}else if(bj=="hh"){
  cc.addChild(btn);
}
if( c.contains( cb ) ){  
  c.removeChild(cb);
}

对的！contains（）就是用来描述组件之间的包含关系

c.removeChild(ca);//c移除它的子组件ca

如果ca不是c子组件，怎么会运行正常呢！！！
