浅谈h5自定义audio(问题及解决)

<!-- cur表示当前时间 max表示总时长 input表示进度条 --> 

 <span class='cur'></span><input type="range" min=0 max=100 class='range' value=0><span class='max'></span>

/* 进度条 */ 

 .range { 

 width: 5.875rem; 

 height: 0.15rem; 

 background: #2386e4; 

 border-radius: 0.25rem; 

 -webkit-appearance: none !important; 

 position: absolute; 

 top: 3.55rem; 

 left: 6rem; 

 } 

 /* 进度滑块 */ 

 .range::-webkit-slider-thumb { 

 width: 0.5rem; 

 height: 0.5rem; 

 background: #fff; 

 border: 1px solid #f18900; 

 cursor: pointer; 

 border-radius: 0.25rem; 

 -webkit-appearance: none !important; 

 }

//将秒数转为00:00格式 

 function timeToStr(time) { 

 var m = 0, 

 s = 0, 

 _m = '00', 

 _s = '00'; 

 time = Math.floor(time % 3600); 

 m = Math.floor(time / 60); 

 s = Math.floor(time % 60); 

 _s = s < 10 ? '0' + s : s + ''; 

 _m = m < 10 ? '0' + m : m + ''; 

 return _m + ":" + _s; 

 } 

 //触发播放事件 

 $('.play').on('click',function(){ 

 var audio=document.getElementById('ao'); 

 audio.play(); 

 setInterval(function(){ 

 var t=parseInt(audio.currentTime); 

 $(".range").attr({'max':751}); 

 $('.max').html(timeToStr(751)); 

 $(".range").val(t); 

 $('.cur').text(timeToStr(t)); 

 },1000); 

 }); 

 //监听滑块，可以拖动 

 $(".range").on('change',function(){ 

 document.getElementById('ao').currentTime=this.value;$(".range").val(this.value); 

 });
