为什么这个jQuery选择器不工作？

Question

JavaScript的:

<script>

$('#aboutme').on('hover', function(){
    console.log("All the stuff");
    /* $("#aboutmedropdown").css("dispay","block"); */
});

</script>

HTML(css inline for now):

            <div class="nav">
                <ul class="navlist">
                    <li style="position: relative;"><a href="#"><img src="/img/nav-home.png" alt="Navigation Home"></a></li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-about.png" id="aboutme" alt="Navigation About"></a>
                        <div id="aboutmedropdown" style="width: 150px; position: absolute; background-color: #FFFFFF;">
                            <ul style="list-style: none; padding: 0; margin: 0; border-bottom: 5px solid #8cc419;" class="sub_menu">
                                <li style="display: block; font-size: 16px; line-height: 20px; text-align: center; border-bottom: 1px solid #8cc419;"><a href="#" style="color: #8CC419;">About Me</a></li>
                                <li style="display: block; font-size: 16px; line-height: 20px; color: #8CC419; text-align: center; border-bottom: 1px solid #8cc419;"><a href="#" style="color: #8CC419;">Testimonials</a></li>
                            </ul>
                        </div>
                    </li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-yoga.png" alt="Navigation Yoga"></a></li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-pilates.png" alt="Navigation Pilates"></a></li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-fitness.png" alt="Navigation Fitness"></a></li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-media.png" alt="Navigation Media"></a></li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-fitcamp.png" alt="Navigation Fitcamp"></a></li>
                    <li style="position: relative;"><a href="#"><img src="/img/nav-blog.png" alt="Navigation Blog"></a></li>
                </ul>
            </div>

我正在检查元素并且非常清楚地看到我在悬停在上面的图像上有正确的ID - #aboutme.

我正在查看页面源代码,并看到我<script>和jQuery,都已加载.

然而,当我将鼠标悬停在图像上aboutme时,控制台中没有任何反应.

有任何想法吗？

不要使用hover与on,使用mouseout或同等学历mouseenter mouseout(一起):

或者像这样使用悬停方法:

$('#aboutme').hover(function() {
  console.log('hover in');
}, function() {
  console.log('hover out');
});
