Question

我正在创建一个骰子游戏。我正在尝试这样做，以便用户可以在循环之后重新单击按钮，以重置页面再次播放。我的直觉告诉我一个if语句，但经过几次尝试，我无法弄清楚如何设置它。我能够更改按钮值以显示＆＃34;再次播放＆＃34;按下之后，我只需要在用户重新按下按钮后重新加载页面，然后重新播放。＆＃34;任何帮助将不胜感激。

Answer 1

如果我正确理解了您的代码，您可以重新加载页面：

function rollDice(){
    if (document.getElementById("playAgain").value=="Play Again")
        location.reload();
    ...

或将其重置为初始状态：

function rollDice() {
    var rolls = new Array();
    var maxMoney = 0;
    var rollCountMoney = new Array();
    var count = 0;
    var startingBet = 0;
    var betStarter = new Array();
    var mostRoll = 0;
    document.getElementById("display").innerHTML = "";
    document.getElementById("starter").innerHTML = "";
    document.getElementById("highPot").innerHTML = "";
    document.getElementById("rollPot").innerHTML = "";
    ...

Answer 2

最简单的方法是再次添加第二个按钮，如

<button id="play-again-button" style="display:none" onclick="location.reload()">play again</button >

然后在需要时通过

显示

document.getElementById("play-again-button').style.display = "block";

如果您想要真正刷新页面。或者将该按钮联系到一个重置事物的js函数。

循环结束后重置页面
