title: Change Text with click Events
challengeType: 6
forumTopicId: 301500

## Description
<section id='description'>
When the click event happens, you can use JavaScript to update an HTML element.
For example, when a user clicks the "Get Message" button, it changes the text of the element with the class <code>message</code> to say "Here is the message".
This works by adding the following code within the click event:
<code>document.getElementsByClassName('message')[0].textContent="Here is the message";</code>
</section>

## Instructions
<section id='instructions'>
Add code inside the <code>onclick</code> event handler to change the text inside the <code>message</code> element to say "Here is the message".
</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: Your code should use the <code>document.getElementsByClassName</code> method to select the element with class <code>message</code> and set its <code>textContent</code> to the given string.
    testString: assert(code.match(/document\s*\.getElementsByClassName\(\s*?('|")message\1\s*?\)\[0\]\s*\.textContent\s*?=\s*?('|")Here is the message\2/g));

```
