CSS: 

/* === POPUP WINDOW === */
#jQ_popup_window{
    background: rgba(0,0,0,0.6);

/* #POPUP WINDOW */
jQuery: 

   // POPUP WINDOW:
   var scrT = $(window).scrollTop();
   $(window).scroll(function(){
      scrT = $(window).scrollTop(); 
   });
   // GET and use WINDOW HEIGHT //
    $.getDocHeight = function(){
        var D = document;
        return Math.max(Math.max(D.body.scrollHeight, D.documentElement.scrollHeight), Math.max(D.body.offsetHeight, D.documentElement.offsetHeight), Math.max(D.body.clientHeight, D.documentElement.clientHeight));
    };  

    // POPUP WINDOW (lightbox for video and other)  
    // GET WINDOW SCROLLtop OFFSET
$('[data-full]').on('click', function(e){
    e.preventDefault();
    $('#jQ_popup').css({
        top: scrT+15
    }).find('img').remove();
    $('#jQ_popup_window').height($.getDocHeight).fadeTo(0,0).css({
        marginLeft:0
    }).fadeTo(600,1);
    var imgToLoad = $(this).data('full');
  $('<img>', {src:imgToLoad, width:'100%'}).appendTo('#jQ_popup');

});
// close popup
$('#jQ_popup_close, #jQ_popup_window').on('click', function(){      
    $('#jQ_popup_window').fadeTo(600,0,function(){
        $(this).hide();         
    });
});
$('#jQ_popup').on('click', function(ev){
    ev.stopPropagation();
});
// end POPUP WINDOW

解决问题的方法就是移动JavaScript文件的导入。它应该放在两个<img>标签的末尾。

<img src="http://placehold.it/250x150/cf5" data-full="http://placehold.it/860x590/cf5" alt="" />
<img src="http://placehold.it/250x150/fof" data-full="http://placehold.it/860x590/fof" alt="" /> 
<script type = "text/javascript" src ="trouble.js"></script>
这是标准的做法加载你的javascript文件要么最后在头部或最后在正文。将脚本标签放在其他html标签(如<div>)中是不正常的，但我从未见过这样的不良影响。
