Using a method would be jQuery like: -> http://api.jquery.com/first/ -> http://api.jquery.com/last/ but jQuery didn't had much choice has JS getter / setter are not supported by older browsers
The DOM API expose first / last child via properties since DOM level 1 -> http://www.w3.org/TR/dom/#dom-node-firstchild -> http://www.w3.org/TR/dom/#dom-node-lastchild As does Element Traversal -> http://www.w3.org/TR/2007/WD-ElementTraversal-20070727/#elementTraversal-firstElementChild -> http://www.w3.org/TR/2007/WD-ElementTraversal-20070727/#elementTraversal-lastElementChild Properties would be more logic to me but I'm not sure if they are really necessary It provides a little more semantic friendly access and is a little more friendly for autocompletion On 28 juil. 2013, at 14:13, David Bruant wrote: > Hi, > > Asked by Angus Croll [1].
