What is the difference between innerHTML, innerText and value in JavaScript?


Unlike innerText, though, innerHTML lets you work with HTML rich text and doesn’t automatically encode and decode text. In other words, innerText retrieves and sets the content of the tag as plain text, whereas innerHTML retrieves and sets the content in HTML format.


The examples below refer to the following HTML snippet:

<div id="test">
   Warning: This element contains <code>code</code> and <strong>strong language</strong>.

The node will be referenced by the following JavaScript:

var x = document.getElementById('test');


Sets or gets the HTML syntax describing the element’s descendants

// => "
// =>   Warning: This element contains <code>code</code> and <strong>strong language</strong>.
// => "

This is part of the W3C’s DOM Parsing and Serialization Specification. Note it’s a property of Element objects.


Sets or gets the text between the start and end tags of the object

// => "Warning: This element contains code and strong language."
  • innerText was introduced by Microsoft and was for a while unsupported by Firefox. In August of 2016, innerText was adopted by the WHATWG and was added to Firefox in v45.
  • innerText gives you a style-aware, representation of the text that tries to match what’s rendered in by the browser this means:
    • innerText applies text-transform and white-space rules
    • innerText trims white space between lines and adds line breaks between items
    • innerText will not return text for invisible items
  • innerText will return textContent for elements that are never rendered like <style /> and `
  • Property of Node elements


Gets or sets the text content of a node and its descendants.

// => "
// =>   Warning: This element contains code and strong language.
// => "

While this is a W3C standard, it is not supported by IE < 9.

  • Is not aware of styling and will therefore return content hidden by CSS
  • Does not trigger a reflow (therefore more performant)
  • Property of Node elements


This one depends on the element that you’ve targeted. For the above example, x returns an HTMLDivElement object, which does not have a value property defined.

x.value // => null

Input tags (<input />), for example, do define a value property, which refers to the “current value in the control”.

<input id="example-input" type="text" value="default" />
  document.getElementById('example-input').value //=> "default"
  // User changes input to "something"
  document.getElementById('example-input').value //=> "something"

From the docs:

Note: for certain input types the returned value might not match the
value the user has entered. For example, if the user enters a
non-numeric value into an <input type="number">, the returned value
might be an empty string instead.

Sample Script

Here’s an example which shows the output for the HTML presented above:

var properties = ['innerHTML', 'innerText', 'textContent', 'value'];

// Writes to textarea#output and console
function log(obj) {
  var currValue = document.getElementById('output').value;
  document.getElementById('output').value = (currValue ? currValue + '\n' : '') + obj; 

// Logs property as [propName]value[/propertyName]
function logProperty(obj, property) {
  var value = obj[property];
  log('[' + property + ']'  +  value + '[/' + property + ']');

// Main
log('=============== ' + properties.join(' ') + ' ===============');
for (var i = 0; i < properties.length; i++) {
  logProperty(document.getElementById('test'), properties[i]);
<div id="test">
  Warning: This element contains <code>code</code> and <strong>strong language</strong>.
<textarea id="output" rows="12" cols="80" style="font-family: monospace;"></textarea>


In simple words:

  1. innerText will show the value as is and ignores any HTML formatting which may
    be included.
  2. innerHTML will show the value and apply any HTML formatting.


InnerText property html-encodes the content, turning <p> to &lt;p&gt;, etc. If you want to insert HTML tags you need to use InnerHTML.
