HTMLInputElement: value property

{{ APIRef("HTML DOM") }} 

The value property of the {{DOMxRef("HTMLInputElement")}}  interface represents the current value of the {{htmlelement("input")}}  element as a string.

This property can also be set directly, for example to set a default value based on some condition.

Value

A string containing the value of the {{htmlelement("input")}}  element, or the empty string if the input element has no value set.

Examples

Retrieving a text input’s value

In this example, the log displays the current value as the user enters data into the input.

HTML

We include an {{htmlelement("input")}}  and an associated {{htmlelement("label")}} , with a {{htmlelement("pre")}}  container for our output.

<label for="given-name">Your name:</label>

<input name="given-name" id="given-name" />

<pre id="log"></pre>

JavaScript

The <pre> element’s {{domxref("HTMLElement.innerText", "innerText")}}  is updated to the current value of the <input> every time a {{domxref("Element/keyup_event", "keyup")}}  event is fired.

const logElement = document.getElementById("log");
const inputElement = document.getElementById("given-name");

inputElement.addEventListener("keyup", () => {
  logElement.innerText = `Name: ${inputElement.value}`;
});
#log {
  height: 20px;
  padding: 0.5rem;
  background-color: #ededed;
}

HTML

We include an <input> of type color:

<label for="color">Pick a color:</label>

<input name="color" id="color" type="color" />

<pre id="log"></pre>

JavaScript

The <pre> element’s {{domxref("HTMLElement.innerText", "innerText")}}  is updated with the default color value (#000000) and then updated every time a {{domxref("HTMLElement/change_event", "change")}}  event is fired.

const logElement = document.getElementById("log");
const inputElement = document.getElementById("color");

logElement.innerText = `Color: ${inputElement.value}`;

inputElement.addEventListener("change", () => {
  logElement.innerText = `Color: ${inputElement.value}`;
});
#log {
  height: 20px;
  padding: 0.5rem;
  background-color: #ededed;
}
