点击背景区域关闭灯箱窗口？

标签： javascript jquery html css lightbox

我开发了一个灯箱功能，我试图弄清楚如何通过点击显示图像背后的背景区来关闭灯箱预览窗口（同时保持图像不受影响）。

这是一个演示片段。在右上角有一个按钮切换控件来关闭灯箱窗口，但我希望能够通过单击图像周围的背景区域来关闭窗口。有什么输入吗？

只使用包含灯箱的div的点击事件，并仅在点击的区域不包含图片时触发事件：

$('.customlightbox-imgwrap').on('click', function(e) {
   if(!$(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");
   } 
});

点击背景

隐藏灯箱

可以通过将 #view 添加到以下代码中来实现。

之前

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

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;
