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="https://www.jb51.net/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。
