有人知道如何开始游戏吗?我可以完成剩下的工作，但刚开始，从数组中获取值是我的问题

基本上，这是一个出于某种原因我想做的hangman游戏，但现在我主要关心的是启动它，从数组关键字中选择一个随机值，并在中上部区域中显示为------

<script>
var keywords =["Infinity","One","Ten","Winner","Chicken"];
var score,c,d,e
score = 0;
function startGame()
{
document.getElementById("hangman").value;
}
function find(x)
{
var found = false;
for ( i =0; i < selectedKeyword.length; i++)
{
if(selectedKeyword.charAt(i) ==x)
{
xxxxx
}
if(found)
{
if(displayKeyword == selectedKeyword)
{
alert("Well Done!");
score++;
xxxxx
}
}
else
{
fails++;
if (fails >=6)
{
alert("GAME OVER!");
xxxxxx
}
document.getElementById("hangman").value= displayedKeyword;
document.getElementById("score").value = score;
document.getElementById("fails").value = fails;
}
function setChartAt (str,index,chr)
{
if(index > str.length-1) return str;
return xxxxx;
}
</script>

基本上，这是一个出于某种原因我想做的绞刑架游戏，但现在我主要关心的是启动它，从数组关键字中选择一个随机值，并在中上部区域显示为------

在startGame函数中，您可以通过以下操作随机化起始值：

var keywordIndex = Math.floor(Math.random() * keywords.length);
selectedKeyword = keywords[keywordIndex];

为了让这个游戏发挥作用，你可能还需要做更多的事情，但我认为这回答了你的问题？

祝你好运！

您可以从Wirde提到的选择要使用的单词开始，然后显示&quot_&quot；并在找到字母时交换它们。

let selectedWord = "Infinity";
var lettersFound = [];
function start(){
lettersFound = [];
for(i=0; i < selectedWord.length; i++){
lettersFound.push("");
}
render();
}
function find(x){
for(i = 0; i < selectedWord.length; i++){
if(selectedWord.charAt(i).toLowerCase() == x && lettersFound[i] === ""){
lettersFound[i] = selectedWord.charAt(i);
}
}
render();
}
function render(){
let shownWord = "";
for(i = 0; i < selectedWord.length; i++){
if(lettersFound[i]===""){
shownWord +="_ ";
}else{
shownWord +=lettersFound[i] + " ";
}
}
let showZone = document.getElementById("msg");
showZone.value = shownWord;
}
