Mozilla Firefox说没有定义Referenceerror事件，没有解决方案

我的代码遇到了麻烦。我搜索并找到了几个解决方案，但没有一个能够解决问题。问题是mozilla firefox给了我一个错误：事件被点头定义。其他浏览器工作正常。我调用该函数的代码：

I have been having troubles with my code. I have searched and found several solutions, but none of them did the trick. The problem is that mozilla firefox gives me an error: event is nod defined. Other browsers work fine. My code to call the function:

var demoMap = '<table class="popup"><tr><td>';
   demoMap += '<span class="close-popup">&#215;</span>';
   demoMap += '<canvas id="map" width="853" height="480"></canvas>';
   demoMap += '</td></tr></table>';

var wayfinder;   
	$(".home-video").click(function () {
		$(".home-attention").append(demoMap);
        
        $(function(){ //Make sure that the page is loaded.
            wayfinder = new Wayfinder3D();
            wayfinder.cbOnDataLoaded = function(){
            
            //Laetud, peida progressbar
            };

            wayfinder.cbOnProgress = function(percentage){
            //Laeb, liiguta progressbari
            };
            wayfinder.options.assetsLocation = '//static.3dwayfinder.com/shared/';
            wayfinder.open("1a07bdc53edb3828f390bc9af7281585");
            
        });
	});
         
	
  $( ".popup" ).click(function() {
    $( this ).fadeOut(500, function () {
      $(this).remove();
    });
  });
