description: > This example shows how a Progress Bar can be rendered and used on the client. The trigger button is supplied with the according JavaScript code, which uses the clientside facility of a Progress Bar.

expected output: > ILIAS shows the rendered Progress Bar and Standard Button. The Progress Bar is initially empty (no progress), and cannot be operated in any way. When the Standard Button is clicked, the Progress Bar value us increased by 10% each time.

After the 10th click, the Progress Bar is finished showing a successful state.

description: > This example shows how a Progress Bar can be rendered and updated by the server. The artificial endpoint uses Progres Bar Instructions to order the clientside Progress Bar to perform a desired update. A Standard Button can be used to start this process.

expected output: > ILIAS shows the rendered Progress Bar and Standard Button. The Progress Bar is initially empty (no progress), and cannot be operated in any way. When the Standard Button is clicked, the Progress Bar value us increased by 10% ~every second. After the ~10 seconds, the Progress Bar will be finished showing a

successful state.
