我想要做的就是更改背景图片每隔3秒。代码工作,但它不改变图像,停留在'slideShow-1.jpg'。如果我删除过渡(元素);部分,图像旋转得很好。我该怎么做才能使它工作?我仍然是Javascript的初学者,当我变得更好的时候会学习jquery。对不起,我的语法。
在你的代码片段中添加Html – Tushar
尝试一次使用Style backgroundImage属性即'element.style.backgroundImage =“url('”+ images [0] +“')”;'你还需要__move'var images = []'to global scope__ – Satpal
@Satpal - 'images'作为函数参数传递,它不需要是全局的。 – Quentin
