This article shares the two effects of making an accordion with pure js+html and making an accordion with pure css+html for your reference. The specific content is as follows
1. Pure css+html accordion effect
This kind of accordion written in CSS is relatively simple. It is mainly applied to the transition attribute in CSS.
The code is as follows:
<!DOCTYPE HTML> <html> <head> <style> body{background: url('bg.gif') repeat;} ul,li,p{margin: 0px;padding: 0px;list-style: none;} #div{width: 1180px;height: 405px;border:5px solid #ccc;padding: 0px;margin: 0px auto;overflow: hidden;} .list{width: 3200px;} .list li{float: left;width: 170px;height: 500px;;position: relative; -moz-transition:width 2s; transition: width 2s; -moz-transition: width 2s; /* Firefox 4 */ -webkit-transition: width 2s; /* Safari 和 Chrome */ -o-transition: width 2s; /* Opera */ } .list:hover li{width: 107px;} .list li:hover{width: 538px;} .list li p{width: 100%;height: 100%;opacity: 0.5;position: absolute;top: 0px;left: 0px;background: black; } .list li:hover p{opacity:0} </style> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script type="text/javascript"> </script> </head> <body > <div id="div"> <ul class="list"> <!--如果设置父级与子级之间没有空隙的话,将margin和padding设为0即可--> <li><img src="image/1.jpg" style="width:538px;height:405px;"><p></p></li> <li><img src="image/2.jpg" style="width:538px;height:405px;"><p></p></li> <li><img src="image/3.jpg" style="width:538px;height:405px;"><p></p></li> <li><img src="image/4.jpg" style="width:538px;height:405px;"><p></p></li> <li><img src="image/5.jpg" style="width:538px;height:405px;"><p></p></li> <li><img src="image/6.jpg" style="width:538px;height:405px;"><p></p></li> <li><img src="image/7.jpg" style="width:538px;height:405px;"><p></p></li> </ul> </div> </body> </html>
2. Making accordion with pure js+html
A problem with this accordion is that when each li is moved individually, there is no problem, but when the movement is very fast, there is a gap in the rightmost li. I think it's a timer problem, that is, before each li has returned to its position, the next li starts moving. But my timer has been turned off.
Can anyone please leave me a message and help me figure out how to change it!
The code is as follows:
<!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>手风琴效果</title> <link href="style.css" rel="stylesheet" type="text/css" /> <script src="perfectMove2.js"></script> <script type="text/javascript"> window.onload=function() { var oDiv=document.getElementById('show1'); var iMinWidth=9999999; var aLi=oDiv.getElementsByTagName('li'); var aSpan=oDiv.getElementsByTagName('span'); var i=0; var bool=false; for(i=0;i<aLi.length;i++) { aSpan[i].index=i; aSpan[i].onmouseover=function () { for(i=0;i<aLi.length;i++) { startMove(aLi[i],{width:this.offsetWidth});//调用运动函数 bool=true; } if(bool) { startMove(aLi[this.index],{width:552}); } } } }; </script> </head> <body> <div id="show1"> <ul> <li class="active"> <span class="bg0">这是第一个</span> <img src="images/1.jpg" /> </li> <li > <span class="bg1">这是第二个</span> <img src="images/2.jpg" /> </li> <li > <span class="bg2">这是第三个</span> <img src="images/3.jpg" /> </li> <li> <span class="bg3">这是第四个</span> <img src="images/4.jpg" /> </li> <li> <span class="bg4">这是第五个</span> <img src="images/5.jpg" /> </li> <li> <span class="bg5">这是第六个</span> <img src="images/6.jpg" /> </li> </ul> </div> </body> </html>
perfectMove2.js code is as follows:
function getStyle(obj,attr)//用此种方法获取样式中的属性 { if(obj.currentStyle) { return obj.currentStyle[attr]; } else { return getComputedStyle(obj,false)[attr]; } } function startMove(obj,json,fn) { clearInterval(obj.timer);//清除定时器 obj.timer=setInterval(function () { var stop=true; for(var attr in json) { var iCur=0; if(attr=='opacity') { iCur=parseInt(parseFloat(getStyle(obj, attr))*100);//这里加parseInt是避免div的数值不稳定,在波动 } else { iCur=parseInt(getStyle(obj, attr)); } var iSpeed=(json[attr]-iCur)/8; iSpeed=iSpeed>0?Math.ceil(iSpeed):Math.floor(iSpeed); if(iCur!=json[attr]) { stop=false; } if(attr=='opacity') { obj.style.filter='alpha(opacity:'+(iCur+iSpeed)+')'; obj.style.opacity=(iCur+iSpeed)/100; } else { obj.style[attr]=iCur+iSpeed+'px'; } } if(stop) { clearInterval(obj.timer); if(fn){fn();} } }, 30) }
The above is the entire content of this article. I hope it will be helpful to everyone in learning javascript programming.
