[javascript] jQuery trigger event when click outside the element

$(document).click(function(evt) {
    var target = evt.currentTarget;
    var inside = $(".menuWraper");
    if (target != inside) {
        alert("bleep");
    }

});

I am trying to figure out how to make it so that if a user clicks outside of a certain div (menuWraper), it triggers an event.. I realized I can just make every click fire an event, then check if the clicked currentTarget is same as the object selected from $(".menuWraper"). However, this doesn't work, currentTarget is HTML object(?) and $(".menuWraper") is Object object? I am very confused.

The most common application here is closing on clicking the document but not when it came from within that element, for this you want to stop the bubbling, like this:

$(".menuWrapper").click(function(e) {
  e.stopPropagation(); //stops click event from reaching document
});
$(document).click(function() {
  $(".menuWrapper").hide(); //click came from somewhere else
});

All were doing here is preventing the click from bubbling up (via event.stopPrpagation()) when it came from within a .menuWrapper element. If this didn't happen, the click came from somewhere else, and will by default make it's way up to document, if it gets there, we hide those .menuWrapper elements.

I do not think document fires the click event. Try using the body element to capture the click event. Might need to check on that...

try these..

$(document).click(function(evt) {
    var target = evt.target.className;
    var inside = $(".menuWraper");
    //alert($(target).html());
    if ($.trim(target) != '') {
        if ($("." + target) != inside) {
            alert("bleep");
        }
    }
});

$(document).click((e) => {
  if ($.contains($(".the-one-you-can-click-and-should-still-open").get(0), e.target)) {
  } else {
    this.onClose();
  }
}); 

I know that the question has been answered, but I hope my solution helps other people.

stopPropagation caused problems in my case, because I needed the click event for something else. Moreover, not every element should cause the div to be closed when clicked.

My solution:

$(document).click(function(e) {
    if (($(e.target).closest("#mydiv").attr("id") != "mydiv") &&
        $(e.target).closest("#div-exception").attr("id") != "div-exception") {
        alert("Clicked outside!");
    }
});

function handler(event) {
 var target = $(event.target);
 if (!target.is("div.menuWraper")) {
  alert("outside");
 }
}
$("#myPage").click(handler);

if you have child elements like dropdown menus

$('html').click(function(e) {
  //if clicked element is not your element and parents aren't your div
  if (e.target.id != 'your-div-id' && $(e.target).parents('#your-div-id').length == 0) {
    //do stuff
  }
});

This code will open the menu in question, and will setup a click listener event. When triggered it will loop through the target id's parents until it finds the menu id. If it doesn't, it will hide the menu because the user has clicked outside the menu. I've tested it and it works.

function tog_alerts(){
   if($('#Element').css('display') == 'none'){
       $('#Element').show();
       setTimeout(function () {
           document.body.addEventListener('click', Close_Alerts, false);
       }, 500);
   }
}

function Close_Alerts(e){
   var current = e.target;
   var check = 0;
   while (current.parentNode){
      current = current.parentNode
      if(current.id == 'Element'){
         check = 1;
      }
   }
   if(check == 0){
      document.body.removeEventListener('click', Close_Alerts, false);
      $('#Element').hide();         
   }
}

    var visibleNotification = false;

  function open_notification() {
        if (visibleNotification == false) {
            $('.notification-panel').css('visibility', 'visible');
            visibleNotification = true;
        } else {
            $('.notification-panel').css('visibility', 'hidden');
            visibleNotification = false;
        }
    }

    $(document).click(function (evt) {
        var target = evt.target.className;
        if(target!="fa fa-bell-o bell-notification")
        {
            var inside = $(".fa fa-bell-o bell-notification");
            if ($.trim(target) != '') {
                if ($("." + target) != inside) {
                    if (visibleNotification == true) {
                        $('.notification-panel').css('visibility', 'hidden');
                        visibleNotification = false;
                    }
                }
            }
        }
    });

try this one

    $(document).click(function(event) {

        if(event.target.id === 'xxx' )
            return false;
        else {
              // do some this here
        }

    });
