当我将鼠标悬停在div上时,我正试图找到一种从一个背景图像过渡到另一个背景图像的方法。
以下是演示:
这是我的代码
$('#cat').hover(function(){
$('.image').css('background-image',
"url('https://images.unsplash.com/photo-1485198963969-3f6b12e49abb')");
});
有什么想法吗?

首先,您缺少<h1>
的ID,因为您的JQuery
选择了ID为cat,dog和rabbit的元素。
第二,你应该改变的是'.bg'类的background
,而不是'.image'类
HTML
<h1 id="cat">CAT</h1>
<h1 id="dog">DOG</h1>
<h1 id="rabbit">RABBIT</h1>
JS
$('#cat').hover(function(){
$('.bg').css('background-image', "url('https://images.unsplash.com/photo-1485198963969-3f6b12e49abb')");
});
$('#dog').hover(function(){
$('.bg').css('background-image', "url('https://images.unsplash.com/photo-1469225208447-8329cbd3cb3a')");
});
$('#rabbit').hover(function(){
$('.bg').css('background-image', "url('https://images.unsplash.com/photo-1478754351612-f8b7577a3859')");
});

var images = {
"cat":'https://images.unsplash.com/photo-1485198963969-3f6b12e49abb',
"dog" : 'https://images.unsplash.com/photo-1469225208447-8329cbd3cb3a',
"rabbit" : 'https://images.unsplash.com/photo-1478754351612-f8b7577a3859'
};
$('.menu').hover(function(){
var img = $(this).attr("id");
$('.bg').css('background-image', "url(" + images[img] + ")");
});
