介绍
歌词解析本质上是字符串的查找与分割
按照一定的规则，获取时间与内容
代码
function Lyric_Analysis(Lryic_Content, End = "End", DelStr = "\r\n") {
var Lyric_Text = Lryic_Content; //复制一份歌词，备用
var Lyric_Temp0 = Lyric_Text;//设置临时变量--复制一份歌词，用于统计行数
var Lyric_Temp1 = Lyric_Text;//设置临时变量--复制一份歌词，用于解析
var Lyric_Line = new Array;//用于记录每一行的内容
var Lyric_All_Line = 0;//总行数
var Result = new Array();//结果变量，用于保存各部分的结果
var Cut = new RegExp(DelStr, "g");//要去掉的字符
Result["Size"] = Lryic_Content.length;//获取歌词文件大小
//统计行数(统计"["的数量)---开始
while (Lyric_Temp0.indexOf("[") != -1) {
Lyric_Temp0 = Lyric_Temp0.replace("[", "")
Lyric_All_Line++
}
//统计行数(统计"["的数量)---结束
Result['LineNumber'] = Lyric_All_Line;//获取行数
var Line_Temp0 = 0;//设置临时变量--保存查找的当前行"["结果的位置
var Line_Temp1 = 0;//设置临时变量--保存查找的下一行"["结果的位置
var Line_Temp2 = "";//设置临时变量--保存当前行的内容(时间+歌词)
//解析每行歌词---开始
for (let i = 0; i < Lyric_All_Line; i++) {
Line_Temp0 = Lyric_Temp1.indexOf("[");//查找本行"["位置
Line_Temp1 = Lyric_Temp1.indexOf("[", Line_Temp0 + 1);//查找下一行"["位置
if (Line_Temp1 != -1) {//判断是否是最后一行
Line_Temp2 = Lyric_Temp1.substring(Line_Temp0, Line_Temp1);//截取当前行内容
Line_Temp2 = Line_Temp2.replace(Cut, "");//删除要去掉的字符
Lyric_Line[i] = Line_Temp2;//保存到数组变量，记录每行内容
Lyric_Temp1 = Lyric_Temp1.replace("[", "");//清除本行"["防止干扰
Lyric_Temp1 = Lyric_Temp1.replace("]", "");//清除本行"]"防止干扰
} else {
Lyric_Line[i] = Lyric_Temp1.substr(Line_Temp0);//对最后一行进行处理
}
}
//解析每行歌词---结束
Result['Line'] = Lyric_Line;//保存每行内容的结果
var Time_Start_Temp = 0;//设置临时变量--用于获取本行歌词开始时间
var Time_End_Temp = 0;//设置临时变量--用于获取本行歌词结束时间
var Order_Temp0 = 0; //设置临时变量--用于获取下一行歌词开始时间
var Lyric_Start = new Array;//创建数组--用于保存歌词开始时间
var Lyric_Value = new Array;//创建数组--用于保存歌词内容
var Lyric_End = new Array;//创建数组--用于保存歌词结束时间
//解析每行歌词信息---开始
for (let i = 0; i < Lyric_Line.length; i++) {
Line_Temp0 = Lyric_Line[i].indexOf("]");//获取"]"的位置
Time_Start_Temp = Lyric_Line[i].substring(1, Line_Temp0);//截取每行歌词开始时间信息
Lyric_Start[i] = Time_Start_Temp;//记录每行开始时间
Lyric_Value[i] = Lyric_Line[i].substr(Line_Temp0 + 1);//记录每行文本
Order_Temp0 = i + 1;//跳跃下一行
if (Order_Temp0 < Lyric_Line.length) {//判断最后一行
Line_Temp1 = Lyric_Line[Order_Temp0].indexOf("]");//获取"]"的位置
Time_End_Temp = Lyric_Line[Order_Temp0].substring(1, Line_Temp1);//截取每行歌词结束时间信息
} else {
Time_End_Temp = End;//对最后一行进行处理
}
Lyric_End[i] = Time_End_Temp;//记得每行结束时间
}
//解析每行歌词信息---结束
Result['StartTime'] = Lyric_Start;//保存每行歌词开始时间
Result['LineValue'] = Lyric_Value;//保存每行歌词
Result['EndTime'] = Lyric_End;//保存每行歌词结束时间
return Result;
//输出结果数组
}
返回结果是数组
