ProcessingInstruction: removeAttribute() method

The removeAttribute() method of the ProcessingInstruction removes the attribute with the specified name from the processing instruction.

Syntax

removeAttribute(attrName)

Parameters

attrName: A string specifying the name of the attribute to remove from the processing instruction. If the specified attribute does not exist, removeAttribute() returns without generating an error.

Return value

None (undefined).

Usage notes

You should use removeAttribute() instead of setting the attribute value to null (either directly or using setAttribute()). Many attributes will not behave as expected if you set them to null.

Examples

undefined

Basic usage

const pi = document.createProcessingInstruction("start", 'name="placeholder"');

pi.removeAttribute("name");
console.log(pi);
// logs:
// <?start?>
