How to extract values from an html date input with JavaScript?

To extract values from an HTML date input with JavaScript, you can use the value property of the input element to get the date in the format “yyyy-mm-dd”. Here is an example:

HTML code:

<input type="date" id="myDate">

JavaScript code:

const dateInput = document.getElementById("myDate");
const dateValue = dateInput.value;

console.log(dateValue); // Outputs the date in the format "yyyy-mm-dd"

In this example, we first get a reference to the date input element using the getElementById() method and store it in a variable called dateInput. We then use the value property of the dateInput element to get the date value in the format “yyyy-mm-dd”. This is the default format used by most browsers for date inputs.

Finally, we store the date value in a variable called dateValue and log it to the console. The result is the date in the format “yyyy-mm-dd”, which can be used in further processing or converted to a different format using other JavaScript methods or external libraries.

Note that the date value returned by the value property is a string, so you may need to convert it to a JavaScript Date object or a different format depending on your needs.
