核心代码如下所示：
rush:js;">
$.ajax({
url: "/music/music.txt",type: "get",success: function(data) {
data = jQuery.parseJSON(data);
var length = data.length;
var Now=0;
for (i = 0; i < length; i++) {
$("#musicText li").eq(i).after("" + data[i].text + " ")
}
var player = {
playButton: $(".play"),songText: $(".musicText"),state: 0,//0播放，1暂停
audio: $("#audio").get(0),bind: function() {
//绑定按钮
//播放或暂停
console.log($.type(this))
console.log($.type(this))
var obj = this;
this.playButton.click(function() {
obj.changeState(obj.state ? 0 : 1);
});
//设置声音
$("#voice").click(function(ex) {
var percent = (ex.clientX - $(this).offset().left) / $(this).width();
obj.setVoice(percent);
});
//默认声音 0.8
obj.setVoice(1.0);
//静音
$("#voiceOP").click(function() {
if (obj.muted) {
$(this).removeClass("muted");
obj.audio.muted = false;
obj.muted = false;
} else {
$(this).addClass("muted");
obj.audio.muted = true;
obj.muted = true;
}
});
//设置进度
$("#MusicProgress").click(function(ex) {
var percent = (ex.clientX - $(this).offset().left) / $(this).width();
obj.setProgress(percent,false);
});
//上一首
$("#prev").click(function() {
obj.NowIndex--;
if (obj.NowIndex < 0) obj.nowIndex = obj.list.length - 1;
obj.playSing(obj.nowIndex);
});
//下一首
$("#next").click(function() {
obj.nowIndex++;
if (obj.nowIndex >= obj.list.length) obj.NowIndex = 0;
obj.playSing(obj.NowIndex);
player.audio.play();
});
//绑定事件 - 播放时间改变
this.audio.ontimeupdate = function() {
obj.timeChange();
}
//播放结束
this.audio.onended = function() {
obj.singEnd();
}
},//切换播放状态
changeState: function(_state) {
this.state = _state;
if (!this.state) {
this.playButton.removeClass("pause").addClass("play");
this.pause();
} else {
this.playButton.removeClass("play").addClass("pause");
this.play();
}
},//播放
play: function() {
this.audio.play();
},//暂停
pause: function() {
this.audio.pause();
},timeChange: function() {
var NowSec = Math.floor(this.audio.currentTime);
console.log(NowSec)
console.log(data[Now].time)
if(NowSec>data[Now].time){
Now = Now + 1;
console.log(Now)
$("#musicText li").eq(Now).addClass("active").siblings("li").removeClass("active");
$("#musicText").css("top",-(24*Now)+138)
}
var totalSec = Math.floor(this.audio.duration);
//当前进度显示
var secTip = secFormat(NowSec) + "/" + secFormat(totalSec);
if (secTip.length == 11) $("#secTip").html(secTip);
this.setProgress(NowSec / totalSec,true);
},setVoice: function(percent) {
$("#voice").children(".bar").css("width",percent * 100 + "%");
$("#voice").children("a").css("left",percent * 100 + "%");
this.audio.volume = percent;
},setProgress: function(percent,justCss) {
$("#MusicProgress").children(".bar").css("width",percent * 100 + "%");
$("#MusicProgress").children("a").css("left",percent * 100 + "%");
if (!justCss) this.audio.currentTime = this.audio.duration * percent;
},singEnd: function() {
if (this.style == 0) {
this.NowIndex++;
if (this.NowIndex >= this.list.length) this.NowIndex = 0;
this.playSing(this.NowIndex);
} else {
var index = Math.floor(Math.random() * (this.list.length + 1)) - 1;
index = index < 0 ? 0 : index;
index = index >= this.list.length ? (this.list.length - 1) : index;
this.playSing(index);
this.NowIndex = index;
}
},};
player.bind();
function secFormat(num) {
var m = Math.floor(num / 60);
var s = Math.floor(num % 60);
return makeFormat(m) + ":" + makeFormat(s);
function makeFormat(n) {
if (n >= 10) return n;
else {
return "0" + n;
}
}
}
}
})
然后这里的代码是alpha0.0.1版的，一直在升级ing.
以上所述是小编给大家介绍的基于jQuery实现歌词滚动版音乐播放器的代码，希望对大家有所帮助，如果大家有任何疑问欢迎给我留言，小编会及时回复大家的。
