The removeAttribute() accepts an argument which is the name of the attribute that you want to remove. If the attribute does not exist, the removeAttribute() method wil not raise an error.
Return value
The removeAttribute() returns a value of undefined.
Usage notes
HTML elements have some attributes which are Boolean attributes. To set false to the Boolean attributes, you cannot simply use the setAttribute() method, but you have to remove the attribute entirely using the removeAttribute() method.
For example, the values of the disabled attributes are true in the following cases:
<button disabled>Save Draft</button><buttondisabled="">Save</button><buttondisabled="disabled">Cancel</button>Code language: HTML, XML (xml)
Similarly, the values of the following readonly attributes are true:
<inputtype="text" readonly><textareatype="text"readonly=""><textareatype="text"readonly="readonly">Code language: HTML, XML (xml)
JavaScript removeAttribute() example
The following example uses the removeAttribute() method to remove the target attribute from the link element with the id js:
How it works:
Select the link element with id js using the querySelector() method.
Remove the target attribute by calling the removeAttribute() on the selected link element.
Summary
Use the removeAttribute() to remove an attribute from a specified element.
Setting the value of a Boolean attribute to false will not work; use the removeAttribute() method instead.
