To manipulate form elements using JavaScript, you can access them using the _________________() or ____________________() methods. These methods allow you to select the form element based on its ___________ or a CSS ____.

For example, let's say we have a form with an input field and a submit button:

1<form id="myForm">
2  <input type="text" id="myInput">
3  <button type="submit">Submit</button>
4</form>

We can select the form and add an event listener to handle the form submission:

1const form = ______._________________('myForm');
2
3form.addEventListener('submit', function(event) {
4  event.preventDefault();
5  // Handle form submission
6});

In the code above, we first select the form element using ______________________() and store it in the _________ variable. Then, we add an event listener to the form's ___________ event. Inside the event listener function, we can prevent the default form submission behavior using __________._______________().

You can also access individual form elements inside the event listener function using their ________ or CSS ____.

Form manipulation involves various tasks such as validation, data retrieval, and form submission. Using JavaScript, you can perform these tasks by manipulating the form elements' ___ and __.

1const form = ______._________________('myForm');
2const input = ________.__________________('myInput');
3
4form.addEventListener('submit', function(event) {
5  event.preventDefault();
6
7  // Get the input field value
8  const inputValue = ________.__________;
9
10  // Perform validation
11  if (inputValue.__________ === 0) {
12    alert('Please enter a value');
13    return;
14  }
15
16  // Perform form submission
17  // ...
18});
