我需要使用XHTML 1.0 Transitional显示简单使用confirm()和prompt()函数作为我的赋值任务的一部分。所有代码都需要验证。

当我尝试验证代码时,收到以下错误:

第12行,第24列:文档类型不允许元素“p”在这里

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>java script demonstration</title>
    </head>
    <body>
        <script type="text/javascript">
                    var response=confirm("This box was created using Javascript - Click on OK to continue")
            if (response)
                {document.write("<p>You have just clicked on OK</p>")}
            else 
                {document.write("You have just clicked on Cancel")}     
                    var reply=prompt("Please enter your Name")
            document.write("your name is " + reply +"")
        </script>   
    </body>
</html>

是否可以将p元素合并到代码中,同时仍然通过验证器?

因为您正在使用XHTML,所以您需要将您的JavaScript包装在CDATA中:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <title>java script demonstration</title>
    </head>
    <body>
        <script type="text/javascript">
            //<![CDATA[
            var response=confirm("This box was created using Javascript - Click on OK to continue")
            if (response)
                {document.write("<p>You have just clicked on OK</p>")}
            else 
                {document.write("You have just clicked on Cancel")}     
                    var reply=prompt("Please enter your Name")
            document.write("your name is " + reply +"")
            //]]>
        </script>   
    </body>
</html>

这只是告诉编译器CDATA标记中包含的内容是数据而不是标记的一种方式。如果您打算使用任何内联JS,这是必要的。
