Use the sxc data API to get backend data

This page uses the sxc data API to get data from the backend and display it in a table with JavaScript.


In this tutorial you'll learn how to:
  • Create a $2sxc object using the current Module Id
  • Use the correct data source using .data()
  • Read data using the .getOne(id) query method
  • Read data using the .getAll() query method

Look at the content below to see the effect.
