LU07.A02 - Methods with arguments

• Work type: Individual
• Means of aid: only teaching materials, no websearch, no use of ai.
• Timeframe: 15 Minutes
• Expected result: A Vue-Script, which uses methods to display messages on the screen and increments and decrements a counter.

1. Implementing VUE methods by using arguments.
2. Increment and decrement a counter within a method.
3. Writing own methods and making use of them.

• Code-example: Methods in VUE

• A01: Test the code example above which was provided to you. Describe the behaviour of the script using HTML comments.
• A02: Make sure that everthing is working correctly: The moose-count uses the method addMoose by processing the number we need to count up or down
  1. increments by 1
  2. decrements by -1
  3. increments by +5

A03: Make sure that you have the title <h1> and have correctly named the file: lu07.s02.html

• B01: Currently we can increment by +1 and +5, and decrement by -1.
• B02: Similar to addMoose add method removeMoose which manges the decrement operations and use it.
• B03: Test your results and save it.
• B04: Add more buttons wich can
  1. increment by +10
  2. decrement by -10
  3. decrement by -5
• B05: The aim is to have 3 increment-buttons (+1, +5, +10) and 3 decrement-buttons (-1, -5, -10)

• C01: At 0 we must stop counting, when the count reches the zero.
• C02: Add the case below zero to your removeMoose-method by checking the count with a if-statement
• C03: Check the result: It must stop at zero when the button removeMoose when the count reaches 0.
• C04: In the case below zero the user must be informed accordingly.
