Rather than using the jQuery  parents function  as suggested in the accepted answer   it s better to use  closest for this purpose  As explained in the jQuery api docs   closest checks the element passed and all its parents  whereas  parents just checks the parents  Consequently  this works     function            body   click function e            if    e target  closest   myDiv   length                alert  Clicked inside  myDiv              else                alert  Clicked outside  myDiv

Here s a one liner that doesn t require jquery using Node contains      Get arbitrary element with id  my-element  var myElementToCheckIfClicksAreInsideOf   document querySelector   my-element       Listen for click events on body document body addEventListener  click   function  event        if  myElementToCheckIfClicksAreInsideOf contains event target             console log  clicked inside          else           console log  clicked outside                If you re wondering about the edge case of checking if the click is on the element itself  Node contains returns true for the element itself  e g  element contains element      true  so this snippet should always work   Browser support seems to cover pretty much everything according to that MDN page as well

Instead of using the body you could create a curtain with z-index of 100  to pick a number  and give the inside element a higher z-index while all other elements have a lower z-index than the curtain   See working example here  http   jsfiddle net Flandre 6JvFk   jQuery        curtain   on  click   function e           this  hide        alert  clicked ouside of elements that stand out           CSS    aboveCurtain       z-index  200     has to have a higher index than the curtain        position  relative      background-color  pink      curtain       position  fixed      top  0px      left  0px      height  100       background-color  black      width  100       z-index 100         opacity 0 5    change opacity to 0 to make it a true glass effect
