Element.removeAttribute()

removeAttribute removes an attribute from the specified element.

Syntax

JavaScript
element.removeAttribute(attrName); 
  • attrName is a string that names the attribute to be removed from element.

Example

JavaScript
// <div id="div1" align="left" width="200px"> 
document.getElementById("div1").removeAttribute("align"); 
// now: <div id="div1" width="200px">

Notes

You should use removeAttribute instead of setting the attribute value to null using setAttribute.

Attempting to remove an attribute that is not on the element doesn't raise an exception.
