HTML: Forms in HTML
When interacting with HTML documents, one of the most common actions is entering data into various fields in the document. For example, entering data in the search bar. This is how you search for information with a search engine (for example, Google or Yandex): you enter a query, it's sent to the server (the computer where the site is hosted), and you get the search results as the output.
This interaction is done using forms - a set of fields and action buttons. It is important to remember that HTML cannot handle data that has been submitted through a form. To interact with this data, you need to use programming languages that run on a server, such as JavaScript or PHP. To learn fundamentals of these languages enroll to relevant courses on Code Basics:
Every form begins with the main <form> tag which will contain the fields to be filled and an action button.
<form>
// Inside the form there will be fields for entering data and submit button (to send data)
</form>
The main attribute in the tag <form> is action, the path to the file where the data handler is located. That's where the data will go after you submit the form.
<form action="/search">
// the data will be sent to the /search page after it is filled in
</form>
If this attribute is not specified, the data will go to the same page from which the form was sent.
Instructions
Create a form with a data handler file at /people
The exercise doesn't pass checking. What to do? 😶
If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:
- Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨
Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.
My code is different from the teacher's one 🤔
It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.
In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.
I've read the lessons but nothing is clear 🙄
It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.
By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.

Your exercise will be checked with these tests:
1const { test } = require('tests');
2
3test(({ query, expect }) => {
4 const form = query(document, 'form');
5
6 expect(form).to.have.attr('action', '/people');
7});
8Teacher's solution will be available in:
