javascript - 将值存储在数组中，而不会覆盖之前的猜测字母

我正在创建一个子手游戏，但是当我运行该程序时，正确的猜测会覆盖自己...
我的函数代码猜测一个字母显示在这里...如何将猜测的字母存储在数组“ letterBoxes”中而不覆盖先前的值？

// Globala variabler
var wordList;
var selectedWord;  på
var letterBoxes;
var hangmanImg;
var hangmanImgNr;
var msgElem;

function init() {
var i;
var startGameBtn;
var letterButtons;
wordList =


["BLOMMA","LASTBIL","SOPTUNNA","KÖKSBORD","RADIOAPPARAT","VINTER","SOMMAR","DATORMUS","LEJON","ELEFANTÖRA","JULTOMTE",
            "SKOGSHYDDA","BILNUMMER","BLYERTSPENNA","SUDDGUMMI","KLÄDSKÅP","VEDSPIS","LJUSSTAKE","SKRIVBORD","ELDGAFFEL","STEKPANNA",
            "KASTRULL","KAFFEBRYGGARE","TALLRIK","SOFFBORD","TRASMATTA","FLYGPLAN","FLYGPLATS","TANGENTBORD"];

hangmanImg = document.getElementById("hangman");
msgElem = document.getElementById("message");
startGameBtn = document.getElementById("startGameBtn");
document.getElementById("startGameBtn").onclick = startGame;
letterButtons =
document.getElementById("letterButtons").getElementsByTagName("button");
for (i = 0; i < letterButtons.length; i++) letterButtons[i].onclick =
guessLetter;//anrop av funktionen guessLetter

} // End init
window.onload = init; // Se till att init aktiveras då sidan är inladdad


function startGame() {

randomWord(selectedWord); //ok
showLetterBoxes(letterBoxes);
hangmanImg = "pics/h1.png"; //byt till h0.png när koden är klar
document.getElementById("hangman").src = hangmanImg;
hangmanImgNr = 0; //ok!
}

function randomWord() {
var wordIndex;
wordIndex = parseInt(Math.random() * 29);
selectedWord = wordList[wordIndex];
alert(selectedWord);
}

function showLetterBoxes() {
var i;
var newCode;

newCode = "";
for (i = 0; i < selectedWord.length; i++) {
    newCode += "<span>&nbsp;</span>";
}

document.getElementById("letterBoxes").innerHTML = newCode;

document.getElementById("letterButtons").getElementsByTagName("value").innerHTML;
}

最佳答案

letterBoxes是一个数组。

您不使用+，使用推入功能。

letterBoxes.push("<span>" + letter + "</span >");

和

letterBoxes.push("<span>*</span>");
