<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>滑块</title> <style> .len{ width: 300px; height: 6px; background: #6c6; border-radius: 3px; margin-top:15px; position: relative; } .len b{ display: inline-block; height: 6px; border-radius: 3px; background: #900; position: absolute; } .len span{ position: absolute; width: 10px; height: 10px; border-radius: 5px; background: #090; z-index: 1; top: -2px; left: 0; } .len input[type=range]{ display: none; } </style> </head> <body> <input type="range" min="0" max="500" value="0"> <input type="range" min="0" value="0"> <script> var ranges=document.querySelectorAll("input[type=range]"); ranges.forEach(function(range){ var Div=document.createElement("div"); Div.className="len"; range.parentNode.insertBefore(Div,range); var span=document.createElement("span"); var b=document.createElement("b"); Div.appendChild(span); Div.appendChild(b); Div.appendChild(range); span.onmousedown=function(e){ var x=e.clientX-this.offsetLeft; var maxL=Div.offsetWidth-span.offsetWidth; var maxV=range.max || 100; document.onmousemove=function(e){ var les=e.clientX-x; if(les < 0)les=0; if(les > maxL)les=maxL; span.style.left=les+"px"; b.style.width=les+span.offsetWidth/2+"px"; range.value=les/maxL*maxV; //同步 e.preventDefault(); //阻止默认事件 console.log(range.value) } document.onmouseup=function(){ document.onmousemove=null; document.onmouseup=null; } } }) </script> </body> </html>
插件都可以无限复制,删除即是原有效果
