我目前正在創建一個骰子滾筒。我試圖解決的問題是我的骰子本身就是圖像元素，我想給它們分配數字，以便它們顯示一條警告消息，顯示滾動骰子的數字值。例如，如果在第一個骰子值中滾動的圖像是三個，那麼當我單擊我的「檢查分數」按鈕時，我希望警報在第一條消息中顯示「3」。我現在的問題是警報顯示[對象HTMLImageElement]。用Javascript骰子滾球遊戲中的骰子分配數字
我希望看看我的代碼將更好地解釋事情。 我的完整代碼是在這第一次切割，僅供參考，我相信我應該修改的特定區域將在後面。

我也認爲我可能需要做的是無論是產生的隨機數，顯示在警報。我只是不知道該怎麼做。
這些是控制我的隨機數世代的函數。
function randomNum(zMin, zMax) {
// This function generates, and returns, a random integer
// between zMin and zMax
return Math.floor(Math.random()*(zMax-zMin+1) + zMin);
}
function rollButtonClick() {
rollNum++;
// loop through each of the 5 game dice and set its "src" image
// to one of the 6 random hidden images
for(i=1; i<=5; i++) {
if (gameDieHold[i] === false) {
var tempNumber = randomNum(1,6);
gameDie[i].src = srcImage[tempNumber].src;
if (rollNum === 3) {
canRoll = false;
if (canRoll === false) {
console.log("working");
gameDieHold[1] = true;
gameDieHold[2] = true;
gameDieHold[3] = true;
gameDieHold[4] = true;
gameDieHold[5] = true;
renderGameDieSpans();
rollButton.removeEventListener("click", rollButtonClick, false);
rollButton.disabled = true;
}
}
}
}
}
如果您可以提供任何幫助，那就太好了。這是漫長的一天，我認爲我的大腦有點疲憊。謝謝。如果有什麼我需要澄清或覆蓋，請告訴我。
