本文实例讲述了JS运动框架之分享侧边栏动画实现方法。分享给大家供大家参考。具体实现方法如下：
复制代码 代码如下:<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
*{
margin:0px;
padding:0px;
}
#div1{
width:319px;
height: 340px;
border: 1px solid #FFF;
position: absolute;
top:100px;
left:-320px;
background-image: url(images/1.png);
background-repeat:no-repeat ;
}
#div1 span{
width:30px;
height: 130px;
border: 1px solid blue;
position: absolute;
right:-23px;
top:95px;
background: red;
font-family: "微软雅黑";
color: #FFFFFF;
text-align: center;
line-height: 40px;
border-radius: 0px 200px 200px 0px;
}
</style>
<script type="text/javascript">
window.onload=function(){
var oDiv=document.getElementById("div1");
var oSpan=oDiv.getElementsByTagName('span')[0];
var time=null;
var speed=8;
oDiv.onmouseover=function(){//这里给整个div加鼠标移入的事件
clearInterval(time);
time=setInterval(function(){
if(oDiv.offsetLeft>=0){clearInterval(time);}
else{
oDiv.style.left=oDiv.offsetLeft+speed+'px';
}
},1);
}
oDiv.onmouseout=function(){//这里给整个div加鼠标移出事件
clearInterval(time);
time=setInterval(function(){
if(oDiv.offsetLeft<=-320){clearInterval(time);}
else{
oDiv.style.left=oDiv.offsetLeft-speed+'px';
}
},1);
}
}
</script>
</head>
<body>
<div id="div1">
<span>分享到</span>
</div>
</body>
</html>
优化后的代码:
复制代码 代码如下:<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style type="text/css">
*{
margin:0px;
padding:0px;
}
#div1{
width:319px;
height: 340px;
border: 1px solid #FFF;
position: absolute;
top:100px;
left:-320px;
background-image: url(images/1.png);
background-repeat:no-repeat ;
}
#div1 span{
width:30px;
height: 130px;
border: 1px solid blue;
position: absolute;
right:-23px;
top:95px;
background: red;
font-family: "微软雅黑";
color: #FFFFFF;
text-align: center;
line-height: 40px;
border-radius: 0px 200px 200px 0px;
}
</style>
<script type="text/javascript">
window.onload=function(){
var oDiv=document.getElementById("div1");
var oSpan=oDiv.getElementsByTagName('span')[0];
var time=null;
var spe=8;
var speed=null;
function move(bord){
clearInterval(time);
time=setInterval(function(){
if(oDiv.offsetLeft>bord){speed=-spe;}
else{speed=spe;}
if(oDiv.offsetLeft==bord){clearInterval(time);}
else{
oDiv.style.left=oDiv.offsetLeft+speed+'px';
}
},1);
}
oDiv.onmouseover=function(){//这里给整个div加鼠标移入的事件
move(0);
}
oDiv.onmouseout=function(){//这里给整个div加鼠标移出事件
move(-320);
}
}
</script>
</head>
<body>
<div id="div1">
<span>分享到</span>
</div>
</body>
</html>
希望本文所述对大家的javascript程序设计有所帮助。
