How to get mail id input box to javascript

You can get the value of a mail input box using JavaScript by selecting the input element using a query selector or by using the document.getElementById() method, and then accessing the value property of the element.

Here are a few examples:

Using a query selector:

const mailInput = document.querySelector('#mail-input');
const mailValue = mailInput.value;

In this example, #mail-input is the ID of the input element, and mailValue will contain the value of the input element.

Using document.getElementById():

const mailInput = document.getElementById('mail-input');
const mailValue = mailInput.value;

This is similar to the previous example, but uses the document.getElementById() method to select the input element.

Using a variable:

const mailInput = document.getElementById('mail-input');
const mailValue = mailInput.value;

You can also assign the input element to a variable and then access the value property:

const mailInput = document.getElementById('mail-input');
mailValue = mailInput.value;

You can then use the mailValue variable to perform any necessary actions, such as sending an email or validating the input.

Note that these examples assume that the input element has an ID of mail-input. You should replace this with the actual ID of your input element.

Also, you can use addEventListener to get the value of the input element when the user submits the form:

const form = document.getElementById('myForm');
form.addEventListener('submit', function(event) {
  event.preventDefault();
  const mailValue = document.getElementById('mail-input').value;
  // do something with the mailValue
});

This code will get the value of the input element when the form is submitted, and then do something with that value.
