我如何定位动画片段的动态名称，它是另一个动画片段的 child

Question

我正在尝试控制位于另一个动画片段中的动画片段，问题是 child 动画片段具有动态实例名称，请查看此示例：

var myvar = "2";

mc_1.mc_2.y = 0; // that's ok

但如果我尝试：

mc_1.this["mc_"+myvar"].y = 0;    

Syntax error: expecting identifier before this."`

我试试：

this["mc_1.mc_"+myvar"].y = 0;

Error #1010: A term is undefined and has no properties.

当我尝试这样做时：

MovieClip("mc_1.mc_"+myvar").y = 0;     

Error #1034: Type Coercion failed: cannot convert "mc_1.mc_2" to flash.display.MovieClip.

再试一次：

mc_1.MovieClip("mc_"+myvar").y = 0; 

Error #1006: MovieClip is not a function.

Answer 1

你可以简单地做：

var myvar:String = '2';

mc_1['mc_' + myvar].y = 0; 

希望能帮到你。
