removeAttribute removes an attribute from the specified element.
Syntax
element.removeAttribute(attrName);
attrNameis a string that names the attribute to be removed from element.
Example
// <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.
