javascript - Unable to change background of div containing unordered list -

Just want to change the background dynamically, do not feel able to do this, what do I remember here? I should clarify, that this is the backdrop of the container device I'm trying to change ...

  $ ('# container'). Click (function () {$ (this) ToggleClass ('bgchange');}); $ ('# Container ul li'). Click (function () {$ (this) .toggleClass ('bgchange');});
