removeAttributeNS removes the specified attribute from an element.

In Firefox 3 and later, this method resets DOM values to their defaults.

Syntax

element.removeAttributeNS(
namespace,
attrName);
  • namespace is a string that contains the namespace of the attribute.
  • attrName is a string that names the attribute to be removed from the current node.

Example

// <div id="div1" xmlns:special="https://www.mozilla.org/ns/specialspace"
//      special:specialAlign="utterleft" width="200px" /> 
d = document.getElementById("div1"); 
d.removeAttributeNS("https://www.mozilla.org/ns/specialspace", "specialAlign"); 
// now: <div id="div1" width="200px" />
