Select All checkbox by Javascript or console

Question

I am having 100 Checkboxes on my web page. For testing purposes I want to tick all those boxes, but manually clicking is time consuming. Is there a possible way to get them tick

Answer 1

  function selectAll(elem)
  {
  for (i = 0; i < elem.length; i++)
    elem[i].checked = true ;
  }

On Click of a button call this method and pass the name of the element(checkboxes-they all should be same named).
