Jquery，背景颜色过渡循环

Question

我希望对背景颜色进行动画处理，以便它在各种预定义颜色之间无限循环。

我不是程序员，对 jquery 很陌生，如果有人能帮助我解决这个问题，我将非常感激

谢谢!

基于 Byron 的解决方案并利用 color animations plugin :

// The array of colours and current index within the colour array
// This array can be hex values or named colours
var colours = ['red', 'orange', 'yellow', 'green', 'blue', 'purple'];
var currIndex = 0;

// The element to animage the background-color of
var elem = $('#element-id');

// Infinitely animate the background-color of your element every second
var loop = setInterval(function(){
    elem.animate({backgroundColor: colours[currIndex++]});

    // Set the current index in the colour array, making sure to loop
    // back to beginning once last colour is reached
    currIndex = currIndex == colours.length ? 0 : currIndex;
}, 1000);
