</body>

我做错了还有另外一种方法，用javascript或PHP，最好是javascript 感谢

Answer 1

您的<select name="b">元素缺少其结束</select>标记，因此以下<select name="l">元素丢失，当您尝试执行form.l.value时收到错误

正确的缩进有助于避免此类问题。

请注意，您可能希望这样做：

var a = parseInt(form.a.value, 10) || 0;
var b = parseInt(form.b.value, 10) || 0;
var c = parseInt(form.c.value, 10) || 0;
var d = parseInt(form.d.value, 10) || 0;
// and so on

...如果某些NaN为value并且确保基数为10，则不会获得""。

使用javascript或PHP添加表单值？
