Thanks but the point is being able to chain it: myTable.qsA('tr') TypeError: myTable.qsA is not a function

  Well, since html elements already have a querySelectorAll function, you could just assign it to a new method "qsA": HTMLElement.prototype.qsA = HTMLElement.prototype.querySelectorAll; Now myTable.qsA('tr') will work. You can try it right here on the HN page in the browser console: HTMLElement.prototype.qsA = HTMLElement.prototype.querySelectorAll; document.querySelector('#hnmain').qsA('tr'); Why do you prefer chaining?

    Perfect, thankyou! I suppose habit plus I find it easier to grok in that order, targetelement->childelements->foreach.

    You'll have to do this in addition to one of the previously discussed solutions if you want something like document.qsA since document isn't an HTMLElement.
