flash - 函数 AS2 中的动态变量名

Question

我有以下问题：

我有一个接收多个变量的函数：

function test( fooValue:String, foobar1:String, foobar2:String, goobar1:String, goobar2:String ) {
//using the values statically
mytext1.text = foobar1;
mytext2.text = foobar2;
mytext3.text = goobar1;
mytext4.text = goobar2;

if ( goobar1 = "problem" ) {
    myProblem.text = this["foo" + fooValue] + this["goo" + fooValue];
}
}
//now here's an example call
test( "bar1","first value ","second value ", "another value", "yet another value");

鉴于 fooValue 在上述调用中具有“bar1”这一事实，我怎样才能使 myProblem.text 显示“第一个值另一个值”

this[ "foo" + fooValue] 给我 undefined

• 编辑了问题并试图更具体。

Answer 1

简单的。

function test( fooValue:String, foobar1:String, foobar2:String, goobar1:String, goobar2:String ) {
//using the values statically
mytext1.text = foobar1;
mytext2.text = foobar2;
mytext3.text = goobar1;
mytext4.text = goobar2;

if ( goobar1 == "problem" ) {
    myProblem.text = this["foo" + fooValue] + this["goo" + fooValue];
}
}
//now here's an example call
test( "bar1","first value ","second value ", "another value", "yet another value")

注意到变化了吗？它是额外=的if(goobar1...。

goobar1 = "problem"设置 goobar1 的值。

goobar1 == "problem"返回 goobar1 的值是否为“问题”

菜鸟的错误，有时也是有经验的人犯的:)

此外

this["foo" + fooValue]等效于this.foobar1（这是无效的，因为该this对象没有任何名为 的属性foobar1）

你这样做：

switch(fooValue) {
    case "bar1":
        myProblem.text = foobar1 + goobar1;
        break;
    case "bar2":
        myProblem.text = foobar2 + goobar2;
        break;
}
