AS3:使用字符串作为变量 [英] AS3: Using string as variable

问题描述

是否有可能从字符串中提取变量名并将其用作变量

Is there a possibility to extract variable name from string and using it as variable

var myvar:String = "flash";
var flash:Number = 10;
trace( myvar as variable );

类似的东西

推荐答案

您可以将其用作对象的属性.

You can use it as a property of an object.

public dynamic class MyClass {
    function MyClass(propName:String, propValue:*) {
        this[propName] = propValue;
    }
}

或

var myvar:String = "flash";
var o : Object = {};
o[myvar] = 10;
trace(o.flash); //10

如果你不知道属性名称是什么，那么你应该使用 dynamic 类(Object 默认是 dynamic)

If you don't know what property name is going to be, then you should use dynamic class (Object is dynamic by default)
