用我的代码替换你的代码。

您的javascript代码中存在语法错误。

Answer 2

只需删除标签

即可

<script type="text/javascript">
...
</script>

来自Popup.js

并替换

 &amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;amp;

与

&&

Answer 3

替换它（它位于底部）：

//Press Escape event!  
    $(document).keypress(function(e){  
    if(e.keyCode==27 &amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;amp; popupStatus==1){  
    disablePopup();  
    }  
    });

有了这个：

//Press Escape event!  
$(document).keypress(function(e) {
    if (e.keyCode == 27 && popupStatus == 1) {
        disablePopup();
    }
});

然后在popup.js中删除<script type="text/javascript">和</script>。
