Definition

Element.removeAttribute() removes the attribute with the given name from the element (MDN). If that attribute is missing, the call does nothing and does not throw. Returns undefined.

Pass the required arguments shown below. Check return values and browser support before you rely on the result.

Syntax

Call el.removeAttribute. Start with this line.

JavaScript
el.removeAttribute(attrName)
CallWhat it does
el.removeAttribute(attrName)Primary signature.
el.removeAttribute(...)Call with the arguments your case needs.

Built into the browser. Call removeAttribute(...) on an Element — no import required.

Library declarations
JavaScript
el.removeAttribute(attrName)

Parameters

ParameterDescription
attrNameRequired. String name of the attribute to remove

Return Value

Return ValueDescription
*Always undefined

JavaScript Examples

Example 1 — Remove disabled (MDN)

Enable a control by deleting the disabled attribute.

JavaScript
const el = document.getElementById("div1");
el.removeAttribute("disabled");

console.log(el.hasAttribute("disabled")); // false
console.log(el.outerHTML);
Try It Yourself

How It Works

  1. Select the element. It starts with disabled set.
  2. Call removeAttribute("disabled"). That attribute is deleted (MDN).
  3. Check with hasAttribute. It returns false.
  4. Other attrs stay. width (and the rest) remain unchanged.

Example 2 — Remove class

Strip the entire class attribute in one call.

JavaScript
const box = document.getElementById("box");
box.removeAttribute("class");

console.log(box.getAttribute("class")); // null
console.log(box.className);             // ""
Try It Yourself

How It Works

  1. Target the element that has a class attribute.
  2. Call removeAttribute("class"). The attribute is gone.
  3. getAttribute("class") returns null.
  4. Note: To remove one class token only, use classList.remove instead.

Example 3 — Missing Attribute Is Safe

Calling remove on a name that is not present does not throw.

JavaScript
const el = document.getElementById("box");

el.removeAttribute("title"); // no title → no error (MDN)
console.log("still ok");

// Prefer this over:
// el.setAttribute("title", null); // often wrong (MDN)
Try It Yourself

How It Works

  1. Attribute is absent. title is not on the element.
  2. Call removeAttribute. MDN: no error — quiet no-op.
  3. Script continues. Safe for cleanup without a prior hasAttribute check.
  4. Avoid null. Do not “clear” attrs with setAttribute(name, null) (MDN).
