Jquery在mouseenter上进行动画制作

Question

i'm not sure what is wrong with this script but it just doesn't seem to want to work. What is meant to happen is that the box should fade the color in and out according to mouseenter/leave.

$(document).ready(function() {
    $('.square-box').mouseenter(function() {
        $(this).animate({
            background-color: '#AAAAAA'
        }, 1000);
    });
    $('.square-box').mouseleave(function() {
        $(this).animate({
            background-color: '#CCCCCC'
        }, 1000);
    });
});

You can animate only attributes with numeric values. But you can use this plugin https://github.com/jquery/jquery-color/ for color animation. Try this:

 $(document).ready(function() { $('.square-box').mouseenter(function() { $(this).animate({ "backgroundColor": '#AAAAAA' }, 1000); }); $('.square-box').mouseleave(function() { $(this).animate({ "backgroundColor": '#CCCCCC' }, 1000); }); }); 

 .square-box { width: 200px; height: 200px; line-height: 200px; cursor: pointer; background-color: #CCC; text-align: center; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-color/2.1.2/jquery.color.js"></script> <div class="square-box">TEST BOX</div>

Seems like you cannot animate colors by default in jquery

You can do it with changing css properties.

 $(document).ready(function() { $('.square-box').mouseenter(function() { $(this).css({ "background-color": "#aaa" }); }).mouseleave(function() { $(this).css({ 'background-color': '#CCCCCC' }) }); }); 

 .square-box { width: 200px; height: 200px; line-height: 200px; cursor: pointer; background-color: #CCC; text-align: center; transition: 1s all; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div class='square-box'> TEST BOX </div>

Jquery cannot animate colors by default. But you don't need a plugin. You can do this with CSS transitions much more easily:

 .square-box { width: 200px; height: 200px; line-height: 200px; cursor: pointer; background-color: #CCC; text-align: center; -webkit-transition:background 1s; -moz-transition:background 1s; -o-transition:background 1s; transition:background 1s } .square-box:hover {background:#AAAAAA} 

 <div class='square-box'> TEST BOX </div>
