JavaScript innerHTML没有加载数据

Question

我想从窗口提示中获取用户输入的值，并让它们显示在html页面上的段落标记中。我认为使用document.getElementById("idName").innerHTML会起作用，但它不会显示用户输入的值。

以下是我在JavaScript页面上的代码。我已经调用了需要在页面上执行的方法。 ：

var players = [];
var numberOfMoves = 0;
var currentPlayer = 0;

getPlayerNames(); //Get player names
setPlayerInformation(); //Set the names of the players in paragraph tags with id playerOneInformation and playerTwoInformation

function getPlayerNames()
{
    players[0] = window.prompt("Please Enter Player 1: ", "");
    players[1] = window.prompt("Please Enter Player 2: ", "");
}

function setPlayerInformation()
{
    document.getElementById("playerOneInformation").innerHTML = players[0];
    document.getElementById("playerTwoInformation").innerHTML = players[1];
}
