通过单击背景区域关闭灯箱 Window？

Question

我开发了一个灯箱功能，我正在尝试通过单击显示的图像后面的背景区域（同时保持图像不受影响）来弄清楚如何关闭灯箱预览 window。

这是一个演示片段。右上角有一个按钮切换控件，用于关闭灯箱 window，但我也希望能够通过单击图像周围的背景区域来关闭 window。有输入吗？

更新：解决方案

感谢 Marouen Mhiri，终于让这个工作起来了。在这里更新了我的原始片段：

var $scrollTop = 0;
$('.pic > img').click(function() {
  var $body = $('body');
  $scrollTop = $(window).scrollTop();
  $body.css('position', 'fixed');
  $body.css('top', '-' + $scrollTop + 'px');
  $body.css('background-position', '0 -' + $scrollTop + 'px');
  var srcToCopy = $(this).attr('src');
  $body.find('.imgsrc').attr('src', srcToCopy);
  $body.addClass('no-scroll');
  $('#view').addClass("target");
});

$('#customlightbox-controls').on('click', function() {
  var $body = $('body');
  $body.css('position', '');
  $body.css('background-position', '');
  $scrollTop = $(window).scrollTop($scrollTop);
  $body.removeClass('no-scroll');
  $('#view').removeClass("target");
});

$('.customlightbox-imgwrap').on('click', function(e) {
  if(!$(e.target).hasClass('imgsrc')){
   var $body = $('body');
   $body.css('position', '');
   $body.css('background-position', '');
   $scrollTop = $(window).scrollTop($scrollTop);

点击背景隐藏灯箱

在下面的代码中添加#view即可。

之前

$('#customlightbox-controls').on('click', function()

之后

$('#customlightbox-controls, #view').on('click', function()

var $scrollTop = 0;
$('.pic > img').click(function() {
  var $body = $('body');
  $scrollTop = $(window).scrollTop();
  $body.css('position', 'fixed');
  $body.css('top', '-' + $scrollTop + 'px');
  $body.css('background-position', '0 -' + $scrollTop + 'px');
  var srcToCopy = $(this).attr('src');
  $body.find('.imgsrc').attr('src', srcToCopy);
  $body.addClass('no-scroll');
  $('#view').addClass("target");
});

$('#customlightbox-controls, #view').on('click', function() {
  var $body = $('body');
  $body.css('position', '');
  $body.css('background-position', '');
  $scrollTop = $(window).scrollTop($scrollTop);
  $body.removeClass('no-scroll');
  $('#view').removeClass("target");
});

body {
  background-color: #58d68d;
  margin: 0;
  padding: 0;
  border: 0;
  height: 100%;
  width: 100%;
}

Answer 2

只需使用包含灯箱的 div 的点击事件，仅当点击区域不包含图像时才触发该事件：

$('.customlightbox-imgwrap').on('click', function(e) {
   if(!$(e.target).hasClass('imgsrc')){ // check if target is not the image displayed
     var $body = $('body');
     $body.css('position', '');
     $body.css('background-position', '');
     $scrollTop = $(window).scrollTop($scrollTop);
     $body.removeClass('no-scroll');
     $('#view').removeClass("target");
   } 
});

通过单击背景区域关闭灯箱 Window？
