removeAttribute() method in javascript
removeAttribute() method is used to remove an attribute from the specified element.
removeAttribute() doesn't returns anything.
Example Explanation
- In the above example the button contains the following attributes style, id, onclick.
- When the button is clicked, the button element (document.getElementById('idBtn')) is stored in elem variable.
- Next by using the removeAttribute method style attribute is removed from the button element (elem.removeAttribute("style")). So the button background color will be removed.
- Then using alert method we are displaying the button element (alert(elem.outerHTML)), in here we can see the style attribute is removed from the button.
