取资源的正则规则在某些有点问题

[Xxx-Bin]

document.body.innerHTML.replace(/[\s\S]appsrc : '([\s\S]?)movie([\s\S]?)-list.m3u8'[\s\S]/, "$1mobilev$2.mp4");

下面代码来自直接用 monkey-videos
懒得分析 我自己直接用了

var mp4Url
//拿到视频资源的MP4地址
var scripts = document.querySelectorAll('script'),
script,
reg = /<source[\s\S]+src="([^"]+)"/,
match,
m3u8Reg = /appsrc\s:\s*'([\s\S]+).m3u8'/,
m3u8Match,
i;

for (i = 0; script = scripts[i]; i += 1) {
match = reg.exec(script.innerHTML);
console.log(match);
if (match && match.length > 1) {
mp4Url = match[1].replace('-mobile.mp4', '.flv');
return mp4Url;
}
m3u8Match = m3u8Reg.exec(script.innerHTML);
console.log(m3u8Match);
if (m3u8Match && m3u8Match.length > 1) {
mp4Url = m3u8Match[1].replace('-list', '') + '.mp4';
return mp4Url;
}
}
return mp4Url;
