The name property of the HTMLInputElement interface indicates the name of the <input> element. It reflects the element's name attribute.
A string representing the element's name.
Given the following HTML:
<p>
<label for="planet">Which planet were you born on?</label>
<input id="planet" type="text" name="origin" />
</p>You can use the name property to retrieve or set the <input>'s name:
const inputElement = document.querySelector("#planet");
console.log(`Element's name: ${inputElement.name}`); // "Element's name: origin"
inputElement.name = "planet"; // updates the element's name
