        function alertYea8() {
            document.getElementById('remember').innerHTML = ('<h3>Times up partner, what were they?</h3></br><input name="nine" id="nine" type="text"></input></br><p id="send"></p><input id="answer" name="submit" type="button" onclick="finals()" value="Next"/>');

            var i = document.getElementById('i').innerHTML = (document.getElementById("nine").value);
            document.getElementById('remember').innerHTML = ('<div id="send"><form action="mailto:hubridnoxx@gmail.com" method="POST" enctype="text/plain" name="emailData"></br><input id="data" type="text" size="20" name="data"><br><input type="submit" value="Submit and continue to letters!"></form></div>');

            emailData.data.value = a + b + c + d + e + f + g + h + i;
            }
        </script>

    </div>
</body>

问题出在最后一行，

emailData.data.value = a + b + c + d + e + f + g + h + i;

页面只返回输入id i的值，而不是输入id a-h。相反，它为每个输入id值显示大量[object HTMLInputElement]。我甚至打电话给.value。我该如何解决这个问题

emailData.data.value = a + b + c + d + e + f + g + h + i;

显示一组相应的值？

更新：

我在所有函数之前声明了以下变量：

        var a = document.getElementById("a").value;
    var b = document.getElementById("b").value;
    var c = document.getElementById("c").value;
    var d = document.getElementById("d").value;
    var e = document.getElementById("e").value;
    var f = document.getElementById("f").value;
    var g = document.getElementById("g").value;
    var h = document.getElementById("h").value;
    var i = document.getElementById("i").value;

现在我只回来了......

Answer 1

您的变量a-h在函数内声明，因此它们在这些函数之外不可用。您需要在函数体外部声明a-h，然后在函数内部设置它们的值。

Answer 2

您已在行var i = document.getElementById('i').innerHTML = (document.getElementById("nine").value);中设置变量i。 i指的是变量i，而不是带有id i的控件。

你必须要做

var a = document.getElementById('number').value

等

编辑：啊，我看到你在你的方法中声明了一个......。请记住，var a仅适用于在其中声明的大括号内，因此通过执行var a=0等在脚本的开头声明它们。这称为变量的“范围”。

Answer 3

在包含emailData.data.value = a + b + c + d + e + f + g + h + i;的函数中，i是您声明的唯一变量。您会注意到变量a，b等未在该函数中声明或全局声明。

Answer 4

是否允许使用jQuery，是否将总数传递给emailData.data.value？如果是这样，您可以在finals()函数中使用它：

var total= 0;
$('input', '#email').each(function () {
    total += parseInt($(this).val());
});
emailData.data.value = total;
