Question

你有这个列表，你想跟踪它：

“Bim的”， “范”， “汜”， “的Bam”， “贝姆”， “比姆”， “Beeem”

var list: Array = new Array ( "Bim and Bum","Bom, Bam","Bem,Beem and Beeem"); var ordnenList:Array = list.map( function (item:*,index:int, array:Array):Array{ return (item as String).replace(" und " , ", ").split(", "); } ); 我这样开始，但它不起作用。谢谢： - ）

通常最简单的方法是使用for in循环来实现这些目的。我们可以像往常一样实现string.replace函数，然后再拆分字符串。

我将所有这些停放在一个功能中，以使其更容易。

function breakDownArray(list:Array):Array
{
    var newList:Array = [];             //Use this array for storing changes, so we don't mess up the for in loop.
    for each(var s:String in list)          //For each item in array...
    {
        //We're going to use , as the character to split by in a moment...
        s = s.replace(" and ", ",");    //Replace the " and " separator with a comma.
        //You can keep putting additional search terms in here.

        var splitString:Array = s.split(",");   //Split string using ",".
        newList = newList.concat(splitString); //We combine our newList array with the splitString array.
    }

    return newList;         //Return newList.
}

禁止错误，这里（代码未经测试），输出应该如下所示......

breakDownArray["Bim and Bum","Bom, Bam","Bem,Beem and Beeem"];
//"Bim", "Bum", "Bom", "Bam", "Bem", "Beem", Beeem"

将命令组合成单行代码可能很诱人，就像你最初那样，但要注意你正在进行错误跟踪。有一些例外，但作为一般经验法则，一行代码应完成一项任务，最多两项。
