There seems to be a missing `,` in the code for the label text

[BurayW]

There seems to be a missing , in the code specifying the label text, which causes a delay bug in the later part of that code, like the sidebar bug mentioned in the previous issue. As

     nextText: {
      '/en/': 'NEXT',
      '/': '下一章节'
    }
    crossChapter: true,

Should be

     nextText: {
      '/en/': 'NEXT',
      '/': '下一章节'
    },
    crossChapter: true,
