我开始了创建网页的旅程。我渴望尝试模仿 Windows 10 启动 UI 以及浏览器上的动画。但问题是我还不了解 javascript。如果您不介意，请检查我的代码是否存在一些问题。谢谢。
HTML
<!DOCTYPE html>
<html>
<head>
<title>WinCalc</title>
<link rel="stylesheet" type="text/css" href="index.css">
<script type="text/javascript" src="index.js"></script>
</head>
<body onload="slideShow()">
<form method="POST" action="" autocomplete="off">
<div id="holder">
<div id="wrapper">
<div id="savButtondesc">
<div id="savDesc"> Sum, Average & Max</div>
<div id="savDesc1"> Display Sum, Average & Max of the number inputted.</div>
</div>
<input id="savButton" type="button" name="sav">
</div>
</div>
</form>
</body>
</html>
CSS
@font-face {
font-family: RobotoL;
src:url(fonts/Roboto-Light.ttf);
}
body {
overflow: hidden;
}
#holder {
width: 50%;
height: 100%;
margin-left: 25%;
margin-right: 25%;
position: absolute;
background-color: #34495e;
}
#wrapper {
background-color: white;
position: absolute;
margin-top: 24%;
margin-bottom: 25%;
margin-right: 25%;
margin-left: 25%;
width: 50%;
height: 50%;
}
#savButton {
border-style: none;
background-color: #3498db;
position: relative;
opacity: .1;
height: 50%;
width: 100%;
}
#savButtondesc {
background-color: red;
width: 100%;
height: 50%;
position: absolute;
}
#savDesc {
width: 100;
margin-top: 17%;
margin-bottom: 20%;
margin-right: 10%;
margin-left: 10%;
font-family: RobotoL;
font-size: 30px;
color: white;
transition: 1s;
}
#savDesc1 {
font-family: RobotoL;
font-size: 15px;
color: white;
margin-left: 1%;
margin-top: -50%;
transition: 1s;
opacity: 0;
}
JavaScript
function slideShow() {
setInterval( function show(){
var next = 0;
if (next == 0) {
animate();
next++:
}
else {
reverse();
next--;
}
},1000);
}
function animate(){
document.getElementById('samDesc').style.marginTop = "-2%";
document.getElementById('samDesc1').style.marginTop = "25%";
document.getElementById('samDesc1').style.opacity = "1";
document.getElementById('samDesc').style.opacity = "0";
}
function reverse(){
document.getElementById('samDesc').style.marginTop = "17%";
document.getElementById('samvDesc1').style.marginTop = "-55%";
document.getElementById('samDesc1').style.opacity = "0";
document.getElementById('samDesc').style.opacity = "1";
}
最佳答案
使用slideShow();在您的 JavaScript 代码的末尾。
无论如何，我推荐你使用http://unslider.com/作为 jQuery 插件。
