Question

继承我的代码：

   <body >
    <script type ="text/javascript">
        document.write("Multiplication Table </br> </br>")
        var num = parseInt(prompt(" Enter a number:"));
        var a;

        document.write("<table border = '1' cellpadding = '0' cellspacing = '0>' ")
        for(a=1;a<=10;a++){
            {
            document.write("<tr><td>"+ num + "x" + a + "=" + a * num + "<tr><td>");
            }
        }
        document.write("</table>");
    </script>
</body>

这应该是样本输出：

Answer 1

需要读取数字并循环投掷它们，同时更正了td和tr

的结束

        document.write("Multiplication Table </br> </br>")
        var num1 = parseInt(prompt("Input 1:"));
        var num2 = parseInt(prompt("Input 2:"));
        var a;
for(num=num1;num<=num2;num++){
        document.write("<table border = '0' cellpadding = '0' cellspacing = '0' style='display:inline; margin:5px' >")
        for(a=1;a<=10;a++){
            {
            document.write("<tr><td style='border:solid black 1px;'>"+ num + "x" + a + "=" + a * num + "</td></tr>");
            }
        }
        document.write("</table>");
}

被困在JS的Multiplication表中
