removeAttribute do not return true or false

Question

I am trying to remove attributes of a DOM element using below statement in javascript.

var res = nodes.removeAttribute("style");

but the res is always "undefined" it seems that the removeAttribute function does not return anything (I tested it on firefox browser)

How can I identify that the attribute is successfully removed or not ?

Thanks, Sourabh

Answer 1

node ? ？ It seems that you have an array of node s. Anyway, removeAttribute will not return anything. To check if the attribute has been removed, use hasAttribute afterwards.

node.removeAttribute('foo');
if (node.hasAttribute('foo')) {
  // failed, foo still exists.
}

Answer 2

nodes.removeAttribute("style");

var isTheLanguageWorkingLikeItShouldAndThisCheckIsTotallyPointless = nodes.getAttribute("style");
