Multievent🔖

With Multievent, 26 different interactive event formats can be implemented on a webpage. This JavaScript searches the document for areas enclosed in double curly braces {{…}}. The enclosed content is transformed into an interactive element. Characters between the opening curly braces determine the result. Below is a list of formats and the corresponding character sequences. For example, a small {r{…}} creates an evaluable radio button in front of the enclosed term (see below).

Feedback🔖

For tasks that are evaluated, the following encodings can be added:

:::multievent
{H{Hint displayed after evaluation if the task is correctly evaluated.}}
{h{Hint displayed after evaluation if the task is incorrectly evaluated.}}
