AS3，从String到数据类型x的动态转换

Question

有没有办法动态转换？

这是转换字符串的默认方式：

var toVal：* = int（“5”）;
var toVal：* = Boolean（“true”）;

但我不想这样做：

var type：String =“int”;
var toVal：* = type（“5”）; //＆lt;＆lt;＆lt;＆lt;＆lt;＆lt;我怎么能这样做

Answer 1

尝试以下方法之一：

var type:Class = int;
// or
var type:Class = flash.utils.getDefinitionByName("int") as Class;

var toVal:* = type("5");

示例程序：

var test:* = "5";

var type:Class = flash.utils.getDefinitionByName("int") as Class;

var toVal:* = type("5");

if(test is String) {
    trace("Test is a string"); // traces
}

if(test is int) {
    trace("Test is an int"); // ignored
}

if(toVal is String) {
    trace("toVal is a string"); // ignored
}

if(toVal is int) {
    trace("toVal is an int"); // traces
}
