如何让 jQuery 在每次悬停时识别鼠标悬停在图像上一次
How to get jQuery to recognize mouse over image once per hover
我正在尝试在鼠标悬停在图片上时为图片制作动画。我目前正在使用 "animate.css" 来获取动画。有两个问题:
1) 如何在每次悬停时让我的脚本 jQuery 到 "fire" 一次?例如,如果我创建一个警报,该警报将触发几次(将鼠标放在上面然后将其移开)。
2) 我当前的 jQuery 语法有什么问题?动画不播放。

我的 CSS 文件会导致冲突吗?
提前致谢!
在您的 JS 中,我会改用 mouseenter 和 mouseleave 事件处理程序。根据您的解释,这应该很好用。当鼠标进入 div 时它会触发一次,离开时会触发一次。
$(document).ready(function()
{
$('#me-pic').on('mouseenter', function() {
$(".bounceIn").toggleClass("bounce");
});
$('#me-pic').on('mouseleave', function() {
$(".bounceIn").toggleClass("bounce");
});
});
