html:
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title>slidefont</title> </head> <body> <div class="f-slidefont-box"> <dl class="f-slidefont-box-tag"> <dd class="f-slidefont-tag">谷歌</dd> <dd class="f-slidefont-tag">百度</dd> <dd class="f-slidefont-tag">阿里</dd> <dd class="f-slidefont-tag">苹果</dd> <dd class="f-slidefont-tag">三星</dd> <dd class="f-slidefont-tag">耳机</dd> <dd class="f-slidefont-tag">音箱</dd> <dd class="f-slidefont-tag">电视</dd> <dd class="f-slidefont-tag">谷歌</dd> <dd class="f-slidefont-tag">百度</dd> <dd class="f-slidefont-tag">阿里</dd> </dl> </div> </body> </html>
css:
<style> .f-slidefont-box * { margin: 0; padding: 0; border: none; list-style: none; } .f-slidefont-box { width: 300px; height: 300px; border: 1px black solid; position: relative; } .f-slidefont-box-tag { width: 90%; height: 90%; position: absolute; top: 0; right: 0; bottom: 0; left: 0; margin: auto; } .f-slidefont-tag { position: absolute; display: block; padding: 3px 15px; background-color: #0078f7; border-radius: 10%; color: white; transition:all 1s linear; z-index: 0; transition: all .6s; cursor: pointer; } </style>
js:
<script src="js/glunefishlibrary.js"></script> // 这里引入的是我发过的随随机数 <script> var tagobj = document.getelementsbyclassname('f-slidefont-tag'), offset = true; for(var i=0;i<tagobj.length;i++){ (function(i){ tagobj[i].onmouseover = function(){ offset = false; index = parseint(this.style.zindex); this.style.zindex = 9999; } tagobj[i].onmouseout = function(){ offset = true; this.style.zindex = index; } })(i); } setinterval(preseting,5000) function preseting(){ if(offset){ for(var i=0;i<tagobj.length;i++){ tagobj[i].style.left = f_getsjs(200,20,10) + 'px'; //f_getsjs() 来自前面引入的 glunefishlibrary.js , 具体请移步到我之前的取随机数随笔 tagobj[i].style.top = f_getsjs(200,20,10) + 'px'; tagobj[i].style.backgroundcolor = 'rgb(' + f_getsjs(256,-1,5) + ',' + f_getsjs(256,-1,10) + ',' + f_getsjs(256,-1,15) + ')'; tagobj[i].style.zindex = f_getsjs(200,0,16); } } } </script>
此效果主要通过间隔取两数之间的随机数来改变标签的样式。
