如何通过在打开按钮区域之外单击来关闭菜单？

Question

A menu opens when a specific button is clicked #btn .

I would like to have the menu close, by also clicking outside the button.

Here is the FIDDLE: https://jsfiddle.net/maryisdead/rkapkoLu/

Is this possible?

Here is the javascript:

(function() {
  var btn       = $('#btn');
  menu      = $('nav ul');
  menuHeight    = menu.height();

  $(btn).on('click', function(e) {
    e.preventDefault();
    menu.slideToggle();
  });

  $(window).resize(function(){
    var w = $(window).width();
    if(w > 320 && menu.is(':hidden')) {
      menu.removeAttr('style');
    }
  });
});

Answer 1

You literally want to have action after clicking on something that is not #btn button.

$( document ).ready(function(){
  $('body *').not('#btn').click(function(){
     e.preventDefault();
     menu.slideToggle();
  })
});

Do not forget to unattach the event afterwards.

Answer 2

You can simply set listener on body

        $(".image").on('click', function(e) {
            e.preventDefault();
            menu.slideToggle();
        });

Answer 3

Do this

    $('html').click(function() {
menu.slideUp();
});

$('.nav-wrapper').click(function(event){
    event.stopPropagation();
});

Answer 4

use onblur event. It is the opposite of onfocus and is fired when the element loses the focus

onblur

Answer 5

I would HIGHLY recommend jQuery outsideevents http://benalman.com/projects/jquery-outside-events-plugin/

$(btn).bind("clickoutside", function(event){ // Code to hide your menu. });

It does all the work of finding everything that's "not the button" for you.

I should also mention it does a lot more than clickoutside, like you could check if they focusoutside too so if they use tab shortcuts to navigate the page the menu still closes, etc.
