为什么它不能检测到这些声明的图像对象 - m22,m33 ....？
TypeError：2007 错误＃：参数 child 必须为非空。

代码运行良好，直到选择文本函数然后出错。

看起来您没有实例化m88或m99任何地方。

由于您的语句中没有任何break命令，switch因此即使mode只有 2 个，它也会通过并执行每个案例。

我假设你打算做这样的事情：

switch (mode) {
    case 2: 
        this.setChildIndex(m22,this.numChildren - 1);
        break;
    case 3: 
        this.setChildIndex(m33,this.numChildren - 1);
        break;
    // etc...

}
