문제
I was using the code from Kejun's Blog .
I want to parse a .lrc (which is basically a lyrics file) so as to get the time variable as well as the string(read lyrics) . I tried out this code and could not seem to get the output .
<html>
<head>
<script src="jquery-1.7.1.js"></script>
<script>
$(document).ready(function () {
$.ajax({
type: "GET",
url: "a.txt",
dataType: "text",
success: function (data) {
parseLyric(data);
}
});
});
var _current_lyric = new Array();
function convertLRCLyric(inf) {
inf += "n";
var lyric = inf.match(/([(d{2}:d{2}(.d{1,2}){0,1})]){1,}W*n|([(d{2}:d{2}:d{2}(.d{1,2}){0,1})]){1,}W*n/ig);
var l_s = '',
l_tt, l_ww, l_i, l_ii;
if (!lyric || !lyric.length) {
return;
}
for (l_i = 0; l_i < lyric.length; l_i++) {
l_tt = lyric[l_i].match(/([d{2}:d{2}(.d{1,2}){0,1}])|([d{2}:d{2}:d{2}(.d{1,2}){0,1}])/ig);
l_ww = lyric[l_i].replace(/[S+]/ig, '').replace(/n{1,}/ig, '');
for (l_ii = 0; l_ii < l_tt.length; l_ii++) {
l_tt[l_ii] = l_tt[l_ii].replace(/[/,'').replace(/]/, '');
if (l_tt[l_ii].search(/d{2}:d{2}:d{2}.d{2}/g) >= 0) {
_current_lyric[l_tt[l_ii].substring(0, l_tt[l_ii].length - 1)] = l_ww;
} else if (l_tt[l_ii].search(/d{2}:d{2}:d{2}.d{1}/g) >= 0) {
_current_lyric[l_tt[l_ii]] = l_ww;
} else if (l_tt[l_ii].search(/d{2}:d{2}:d{2}/g) >= 0) {
_current_lyric[l_tt[l_ii] + ".0"] = l_ww;
} else if (l_tt[l_ii].search(/d{2}:d{2}.d{2}/g) >= 0) {
_current_lyric["00:" + l_tt[l_ii].substring(0, l_tt[l_ii].length - 1)] = l_ww;
} else if (l_tt[l_ii].search(/d{2}:d{2}.d{1}/g) >= 0) {
_current_lyric["00:" + l_tt[l_ii]] = l_ww;
} else if (l_tt[l_ii].search(/d{2}:d{2}/g) >= 0) {
_current_lyric["00:" + l_tt[l_ii] + ".0"] = l_ww;
}
}
}
}
function parseLyric(allText) {
_current_lyric = [];
convertLRCLyric(allText);
var ly = "";
for (var time in _current_lyric) {
ly += time + "--" + _current_lyric[time] + "n";
}
alert(ly);
}
</script>
</head>
<body>
</body>
</html>
But i keep getting a blank alert . Any help would be great . Thanks in advance .

Answer :
Ok so i built my own parser ,Here is the code
var contents = " " ;
function readMultipleFiles(evt) {
//Retrieve all the files from the FileList object
var files = evt.target.files;
if (files) {
for (var i = 0, f; f = files[i]; i++) {
var r = new FileReader();
r.onload = (function (f) {
return function (e) {
contents = e.target.result;
processData(contents);
};
})(f);
r.readAsText(f);
}
} else {
alert("Failed to load files");
}
}
document.getElementById('fileinput').addEventListener('change', readMultipleFiles, false);
var allTextLines = " ";
var lyrics = [];
var tim = [] ;
var line = " ";
// parsing the Lyrics
function processData(allText) { // This will only divide with respect to new lines
allTextLines = allText.split(/\r\n|\n/);
next();
}
function next()
{
for (i=0;i<allTextLines.length;i++)
{
if (allTextLines[i].search(/^(\[)(\d*)(:)(.*)(\])(.*)/i)>=0 )// any line without the prescribed format wont enter this loop
{
line = allTextLines[i].match(/^(\[)(\d*)(:)(.*)(\])(.*)/i);
tim[i] = (parseInt(line[2])*60)+ parseInt(line[4]); // will give seconds
lyrics[i]= line[6] ;//will give lyrics
}
}
}

Code php : with format
public function get_lrc_song($song) {
$lyrics_file = $song ['lyrics_file'];
$json = curlClass::getInstance ( true )->fetchURL ( $lyrics_file );
$content = explode ( "\n", $json );
$regix = "$\][^>]+$";
$result = "";
foreach ( $content as $item ) {
$isHas = preg_match ( $regix, $item, $data );
$dt = str_replace ( "]", "", $data[0] );
if ($dt != ""){
$result .= $dt . "\n";
}
}
echo $result;
}
