Question

嘿伙计们，我是核心javascript的新手。我正在学习制作阵列。我写了这段代码，但不知何故pop无效。

 var players=['david','micky','Ryan','Benjamin','fransesco'];
   var totalPlayers=players.length;
   var lastPlayer=players.pop();
   alert=("The Last Player is " + lastPlayer);
   alert("The total number of players are " + totalPlayers);

现在，lastplayer警报未显示。请告诉我我在哪里做错了。谢谢。

Answer 1

这里有语法错误：

alert="The Last Player is " + lastPlayer);

试试这个，它会起作用

alert("The Last Player is " + lastPlayer);

希望有所帮助

Answer 2

3线 alert =“最后一位玩家是”+ lastPlayer）; 它应该是

alert ( "The Last Player is " + lastPlayer);

Answer 3

使您的数组var players=['david','micky','Ryan','Benjamin','fransesco'];全局并在警告后删除=

alert=("The Last Player is " + lastPlayer);

alert("The Last Player is " + lastPlayer);

我的pop方法不起作用
