Question

我复制后来修改了下面的代码。它显示'JQuery的Hello，World！'网页上的字符串。简要展示'Out of JQuery';我的意思是它几乎立刻就消失了。并且代码结束处理，使浏览器在一个循环上运行，在选项卡上显示“连接”。我做错了什么？

<!DOCTYPE html>
<!---******* HEAD *******-->
<head>
    <!-- JQuery -->
    <script src="../js/jquery-3.2.0.js"></script>
    <title>Testing JQuery</title>
</head>

<!---******* BODY *******-->
<body>
    <title>The jQuery Example</title>
    <script type="text/javascript">
        document.write("Java enabled: " + navigator.javaEnabled());
    </script>
    <script type = "text/javascript">
        $(document).ready(function(){
            document.write("JQuery's Hello, World!");
        });
    </script>       
    <p> Out of JQuery </p> <!-- Does not display -->
    </body>
</html>

来源：https://developer.mozilla.org/en-US/docs/Web/API/Document/write

注意：当document.write写入文档流时，在已关闭（加载）的文档上调用document.write会自动调用document.open，这将清除文档。

至于你的其他问题，我无法重新创建它。
