I'm trying to parse .srt but I get an internal error and I can't figure out what is it.
Here is my code:
var subtitles;
jQuery.get('SB_LKRG-eng.srt', function(data) {
//alert(data);
function strip(s) {
return s.replace(/^\s+|\s+$/g,"");
}
srt = data.replace(/\r\n|\r|\n/g, '\n');
//alert(srt);
srt = strip(srt);
//alert(srt);
var srt_ = srt.split('\n\n');
alert(srt_);
var cont = 0;
for(s in srt_) {
st = srt_[s].split('\n');
alert(st);
if(st.length >=2) {
n = st[0];
i = strip(st[1].split(' --> ')[0]);
o = strip(st[1].split(' --> ')[1]);
t = st[2];
if(st.length > 2) {
for(j=3; j<st.length;j++)
t += '\n'+st[j];
}
subtitles[cont].number = n;
subtitles[cont].start = i;
subtitles[cont].end = o;
subtitles[cont].text = t;
//alert(subtitles[cont].start);
}
cont++;
}
});
I can extract the first 4 subtitles and then the code stops and breaks exception: TypeError, I can't understand why...
Here a sample of the subtitles file:

Can anyone help me?
Thank you

Here is one problem:
o = strip(st[1].split(' --> ')[1]);
At this line, when there isn't any ' --> ' to split, the returned length of the array is 1, which errors when you ask for array item 2.
And here is another:
subtitles[cont].number = n;
....
Neither is the subtitles declared, nor its properties .number, ... etc.
Update
Here is a sample that works (switched the jQuery "read srt file" part for the data)
var data = document.getElementById("data").innerHTML;
data = data.replace(/>/g,">");
function strip(s) {
return s.replace(/^\s+|\s+$/g,"");
}
srt = data.replace(/\r\n|\r|\n/g, '\n');
srt = strip(srt);
var srt_ = srt.split('\n\n');
var cont = 0;
var subtitles = [];
for(s in srt_) {
st = srt_[s].split('\n');
if(st.length >=2) {
var st2 = st[1].split(' --> ');
var t = st[2];
if(st.length > 2) {
for(j=3; j < st.length;j++)
t += '\n'+st[j];
}
subtitles[cont] = { number : st[0],
start : st2[0],
end : st2[1],
text : t
}
console.log(subtitles[cont].number + ": " + subtitles[cont].text);
document.body.innerHTML += subtitles[cont].number + ": " + subtitles[cont].text + "<br>";
cont++;
}

</div>It is better to use the following regex to cover them if the number of lines of text in each section increases
/(\d+)\n([\d:,]+)\s+-{2}\>\s+([\d:,]+)\n([\s\S]*?(?=\n{2}|$))/g
View the output on the console
let subtitle = document.getElementById('subtitle').value;
console.log(_subtitle(subtitle));
function _subtitle(text) {
let Subtitle = text;
let Pattern = /(\d+)\n([\d:,]+)\s+-{2}\>\s+([\d:,]+)\n([\s\S]*?(?=\n{2}|$))/g;
let _regExp = new RegExp(Pattern);
let result = [];
if (typeof (text) != "string") throw "Sorry, Parser accept string only.";
if (Subtitle === null) return Subtitle;
let Parse = Subtitle.replace(/\r\n|\r|\n/g, '\n');
let Matches;
while ((Matches = Pattern.exec(Parse)) != null) {
result.push({
Line: Matches[1],
Start: Matches[2],
End: Matches[3],
Text: Matches[4],
})

Hi my friends
2
00:00:00,610 --> 00:00:01,050
In the first line, everything works properly
But there is a problem in the second line that I could not solve :(
3
00:00:01,080 --> 00:00:03,080
But then everything is in order and good
