  • _data.json
  • _layout.ejs
  • computer.ejs

_data.json:
{ "computer": { "productName":"computer", "briefIntro":"balabala..." } }

When visiting product/computer.html, the productName variable in _data.json cannot be rendered only if you change the computer folder name into computerPics or some other names.
