Let’s say we have a DIV container with some content in it. We want to hide that container if the user clicks outside its bounds. Pretty simple solution:

$( document ).mouseup( function( e ) {
    if( $( "#myDiv" ).has( e.target ).length === 0 ) {
        $( "#myDiv" ).hide();
    }
});

#click, #container, #div, #dom, #hide, #jquery
