Javascript-div innerHTML不變

Question

 var score = 0, time = 1, heart = 3; window.onload = function() { var input = document.getElementById("wordTyped"); var timeLeft = document.getElementById("time"); var life = document.getElementById("life"); input.addEventListener("click", timer, false); function timer() { var id = setInterval(countdown, 10); function countdown() { input.removeEventListener("click", timer, false); timeLeft.innerHTML = "Time left: " + (time - 0.01).toFixed(2) + "s"; time = 1 * (time - 0.01).toFixed(2); if (time == 0 && life.innerHTML == "") { clearInterval(id); } else if (time == 0) { --heart; time = 1; life(heart); } } function life(heart) { heart *= 1; // To make sure it is a number type console.log(heart); switch (heart) { case 2: life.innerHTML = "❤️❤️"; console.log(life.innerHTML); break; case 1: life.innerHTML = "❤️"; console.log(life.innerHTML); break; case 0: default: life.innerHTML = ""; console.log(life.innerHTML); break; } /*if(heart === 2) { life.innerHTML = "❤️❤️"; } else if(heart == 1) { life.innerHTML = "❤️"; } else { life.innerHTML = ""; }*/ } } } 

 <div id="wordGenerated">illustration</div> <input id="wordTyped" type="text" /> <div id="time">Time left: 1.00s</div> <div id="score">Score: 0</div> <div id="life">❤️❤️❤️</div> 

我不確定function life(heart)什么問題。

我試圖將“❤️”的數量減少為一，因為時間是0，然后重置為原始值，重復直到heart等於0。

如果我在function timer()范圍之外使用life.innerHTML = " example " ，它將起作用。

使用console.log() ，它表明life.innerHTML 已更改，但是HTML文檔的顯示保持不變，我不明白為什么。

我已經嘗試過.nodeValue ， .innerText和.textContent ，但它們仍然給出相同的結果

Answer 1

life變量和life()函數存在沖突用法。 將life()函數名稱更改為其他類似updateLife()的代碼，您的代碼即可正常工作，

注意：范圍內的變量或函數或對象名稱不能相同。

 var score = 0, time = 1, heart = 3; window.onload = function() { var input = document.getElementById("wordTyped"); var timeLeft = document.getElementById("time"); var life = document.getElementById("life"); input.addEventListener("click", timer, false); function timer() { var id = setInterval(countdown, 10); function countdown() { input.removeEventListener("click", timer, false); timeLeft.innerHTML = "Time left: " + (time - 0.01).toFixed(2) + "s"; time = 1 * (time - 0.01).toFixed(2); if (time == 0 && life.innerHTML == "") { clearInterval(id); } else if (time == 0) { --heart; time = 1; updateLife(heart); } } function updateLife(heart) { heart *= 1; // To make sure it is a number type console.log(heart); switch (heart) { case 2: life.innerHTML = "❤️❤️"; console.log(life.innerHTML); break; case 1: life.innerHTML = "❤️"; console.log(life.innerHTML); break; case 0: default: life.innerHTML = ""; console.log(life.innerHTML); break; } /*if(heart === 2) { life.innerHTML = "❤️❤️"; } else if(heart == 1) { life.innerHTML = "❤️"; } else { life.innerHTML = ""; }*/ } } } 

 <div id="wordGenerated">illustration</div> <input id="wordTyped" type="text" /> <div id="time">Time left: 1.00s</div> <div id="score">Score: 0</div> <div id="life">❤️❤️❤️</div> 

Answer 2

生活和生活功能之間存在沖突，因此您可以像$（“＃life”）。innerHTML =“”或其他任何東西
