Parse a SRT file with jQuery Javascript

Question

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         


        

Answer 1

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 + "
";
        cont++;
    }
}
