Test your skills: Basic controls - Learn web development 编辑

This aim of this skill test is to assess whether you've understood our Basic native form controls article.

Note: You can try out solutions in the interactive editors below, however it may be helpful to download the code and use an online tool such as CodePen, jsFiddle, or Glitch to work on the tasks.

If you get stuck, then ask us for help — see the Assessment or further help section at the bottom of this page.

Basic controls 1

This task starts you off nice and gently by asking you to create two <input> elements, for a user's ID and password, along with a submit button.

  1. Create appropriate inputs for user ID and password.
  2. You should also associate them with their text labels semantically.
  3. Create a submit button inside the remaining list item, with button text of "Log in".

Basic controls 2

The next task requires you to create working sets of checkboxes and radio buttons, from the provided text labels.

  1. Turn the first <fieldset>'s contents into a set of radio buttons — you should only be able to select one pony character at once.
  2. Make it so that the first radio button is selected upon page load.
  3. Turn the second <fieldset>'s content into a set of checkboxes.
  4. Add a couple more hotdog choices of your own.

Basic controls 3

The final task in this set requires you to create a file picker.

  1. Create a basic file picker.
  2. Allow the user to pick multiple files at once.
  3. Allow the file picker to accept JPG and PNG images only.

Assessment or further help

You can practice these examples in the Interactive Editors above.

If you would like your work assessed, or are stuck and want to ask for help:

  1. Put your work into an online shareable editor such as CodePen, jsFiddle, or Glitch. You can write the code yourself, or use the starting point files linked to in the above sections.
  2. Write a post asking for assessment and/or help at the MDN Discourse forum Learning category. Your post should include:
    • A descriptive title such as "Assessment wanted for Basic controls 1 skill test".
    • Details of what you have already tried, and what you would like us to do, e.g. if you are stuck and need help, or want an assessment.
    • A link to the example you want assessed or need help with, in an online shareable editor (as mentioned in step 1 above). This is a good practice to get into — it's very hard to help someone with a coding problem if you can't see their code.
    • A link to the actual task or assessment page, so we can find the question you want help with.
