Question
Following are the requirements for your JavaScript coding. For each requirement, you will prepare a short description of the code you will write and prepare an example of how the code will look in the HTML for the page. Prepare any required element or tag names for your code and document them appropriately. Your code must use the HTML DOM, and you need only to prepare the code for the DOM interaction, not other support functionality that would lead up to the requirements.When the user logs into their support account, use a hidden element on the page to display “Hello” + the name of the user.
Solution
To meet this requirement, we will use JavaScript to interact with the HTML DOM (Document Object Model). We will create a hidden HTML element that will display a greeting message to the user when they log into their support account.
Here's a step-by-step guide on how to achieve this:
- First, we will create a hidden HTML element. This can be a
<p>or<div>element with a unique id. We will set the CSSdisplayproperty tononeto make it hidden.
<p id="greeting" style="display: none;"></p>
- Next, we will write a JavaScript function that changes the
innerTextof this element to "Hello" + the name of the user, and changes thedisplayproperty toblockto make it visible. This function will be called when the user logs in.
function greetUser(username) {
var greetingElement = document.getElementById('greeting');
greetingElement.innerText = 'Hello ' + username;
greetingElement.style.display = 'block';
}
- Finally, we will call this function when the user logs in. The username can be obtained from the login form or from the server response after login. Here's an example of how to call this function:
greetUser('John Doe');
This will change the hidden greeting element to display "Hello John Doe" when the user logs in.

The username must consist of alphabetic characters only(min 3 and max 20) and should be mandatory for all users. Additionally, you want to provide clear instructions to users, prompting them “Enter your full name “ and if a user hovers over the field it should display a tooltip with the message “Please enter your full name as the username“. Which of the following code snippets fulfills all of these requirements?<label for="username">Username:</label><input type="text" id="username" required title="Please enter your full name as the username" placeholder="Enter your full name" pattern='[a-zA-Z]{3,20}'><label for="username">Username:</label><input type="text" id="username" required title="Please enter your full name as the username" placeholder="Enter your full name"><label for="username">Username:</label><input type="text" id="username" required title="Please enter your full name as the username" placeholder="Enter your full name" pattern='[a-zA-Z]'><label for="username">Username:</label><input type="text" id="username" required title="Please enter your full name as the username" placeholder="Enter your name" pattern='[a-zA-Z]{3,20}'>
