先给大家看下效果图,感兴趣的朋友可以参考实现代码

基于jQuery实现歌词滚动版音乐播放器的代码

核心代码如下所示:

$.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("<li>" + data[i].text + "</li>")
}
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 "#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 ":" + 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.
