你不需要jQuery。做一个计数器,每增加一个
毫秒,并根据计数器状态设置颜色。
const element = document.querySelector('.color');
const colors = ['yellow', 'blue', 'red', 'green']; // The colors you want
const colorDuration = 200; // The duration of a color in milliseconds
let colorIndex = 0;
function switchColor() {
element.style.color = colors[colorIndex++ % colors.length];
}
switchColor();
setInterval(switchColor, colorDuration);
<h1 class="color">Hello world, I love you all.</h1>
