从一个数组参数传递到ActionScript方法...（其余的）参数 [英] Pass arguments from an array to an Actionscript method with ...(rest) argument

问题描述

我的问题是这个问题的Flex的换位：

my question is the Flex transposition of this question :

<一个href="http://stackoverflow.com/questions/2925153/can-i-pass-an-array-as-arguments-to-a-method-with-variable-arguments-in-java">Can我传递一个数组作为参数传递给在Java可变参数的方法？

这是我在某些ActionScript code数组，我需要在数组中收录的每个对象传递到一个方法办法（...参数）。

That is, I have an Array in some Actionscript code and i need to pass every object indexed in the array into a method method(...arguments).

有些code要清楚：

private function mainMethod():void{
    var myArray:Array = new Array("1", "2", "3");
    // Call calledMethod and give it "1", "2" and "3" as arguments
}

private function calledMethod(...arguments):void{
    for each (argument:Object in arguments)
        trace(argument);
}

有没有一些方法做什么意见建议？

Is there some way to do what the comment suggests?

推荐答案

这是可能的方式是遍历功能对象本身。调用适用（）就可以将工作：

It's possible by going through the Function object itself. Calling apply() on it will work:

private function mainMethod():void
{
    var myArray:Array = new Array("1", "2", "3");

    // call calledMethod() and pass each object in myArray individually
    // and not as an array
    calledMethod.apply( this, myArray );
}

private function calledMethod( ... args ):void
{
    trace( args.length ); // traces 3
}
