How to implement animation effects and callback functions
Jun 15, 2018 am 11:37 AM
Below I will share with you an example of CSS3 combined with jQuery to achieve animation effects and callback functions. It has a good reference value and I hope it will be helpful to everyone.
In writing the final project, a friend proposed an idea, a special effect to welcome the user when the user logs in successfully, that is, the welcome user information rises from the bottom to the page, and then returns to the bottom.
The problem he encountered was: The prompt information can come out from the bottom, but after it comes out, it cannot go down.
After hearing this, I thought about it and thought of using a callback function to solve this bug, and then simulated entering the homepage (i.e. refreshing the page) when the login is successful, the welcome message pops up and disappears, and I wrote an animation effect similar to this. For reference only:
Rendering:
##The code is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>歡迎動(dòng)畫</title>
<style>
*{margin:0;padding:0;}
p {
margin:0 auto;
width:100%;
height:700px;
overflow:hidden;
position:relative;
}
p {
width:220px;
height:40px;
line-height:40px;
text-align:center;
display:block;color:#900;
background:#ccc;
position:absolute;
bottom:-40px;
left:500px;
}
</style>
</head>
<body>
<p>
<p>歡迎xxx登錄，祝您購物愉快</p>
</p>
<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script>
<script type="text/javascript">
// 函數(shù)入口
$(function(){
show();
});
// 動(dòng)畫函數(shù)
function show(){
// 獲取p盒子的高度
var p = $("p").height();
$(function(){
// 動(dòng)畫函數(shù)
$("p").animate({"bottom":p*9},3000,function(){
// 回調(diào)函數(shù)
$("p").animate({"bottom":-p},6000);
});
});
}
</script>
</body>
</html>Here we mainly use the animate animation property in css3, combined with jQuery to realize the time and direction of animation execution, and finally set the callback function to return the prompt information to the initial position. The above is what I compiled for everyone. I hope it will be helpful to everyone in the future. Related articles:
