我有这个问题:每当我单击div时,我都想添加背景色。永远。但是,即使我单击更多(例如循环),背景也会改变。如何永远设置背景色?
const blocks = document.querySelectorAll('.game div');
const liveNumber = document.querySelector('.lives-num');
let lives = 1;
function letTheGameBegin(e, r) {
const rand = Math.floor(Math.random() * 100);
if (rand < 40) {
e.target.style.backgroundColor = 'green';
} else if (rand < 60) {
e.target.style.backgroundColor = 'yellow';
lives++;
} else if (rand < 90) {
e.target.style.backgroundColor = 'red';
lives--;
} else {
e.target.style.backgroundColor = 'white';
}
liveNumber.innerHTML = lives;
if (lives === 0) {
//document.querySelector('.game-over').style.display = 'flex';
}
}
blocks.forEach(block => block.addEventListener('click', letTheGameBegin));
最佳答案
我认为您的意思是每个div只运行一次JS。
尝试以下示例,看看是否需要它:jsfiddle
function letTheGameBegin(e, r) {
const rand = Math.floor(Math.random() * 100);
if(!e.target.style.backgroundColor){
if (rand < 40) {
e.target.style.backgroundColor = 'green';
} else if (rand < 60) {
e.target.style.backgroundColor = 'yellow';
lives++;
} else if (rand < 90) {
e.target.style.backgroundColor = 'red';
lives--;
} else {
e.target.style.backgroundColor = 'white';
}
liveNumber.innerHTML = lives;
if (lives === 0) {
//document.querySelector('.game-over').style.display = 'flex';
}
}
}
