Question

我有这个问题，我添加了8个文本框，它工作正常，但当我添加更多的文本框，如16文本框，它不会添加最后一个文本框。有没有人遇到过这个问题？提前致谢。

function sum() {

        var basicpay = document.getElementById('basicpay').value;
        var overtime = document.getElementById('overtime').value;
        var regularholiday = document.getElementById('regularholiday').value;
        var specialholiday = document.getElementById('specialholiday').value;
        var allowanceday = document.getElementById('allowanceday').value;
        var others = document.getElementById('others').value;
        var grosspay = document.getElementById('grosspay').value;
        var monthpay13 = document.getElementById('monthpay13').value;
        var absent = document.getElementById('absent').value;
        var tardiness = document.getElementById('tardiness').value;
        var sss = document.getElementById('sss').value;
        var pagibig = document.getElementById('pagibig').value;
        var philhealth = document.getElementById('philhealth').value;
        var cashadvances = document.getElementById('cashadvances').value;
        var withholdingtax = document.getElementById('withholdingtax').value;
        var others = document.getElementById('others').value;



        var result = 

        parseInt(basicpay) + 
        parseInt(overtime) +
        parseInt(regularholiday) +
        parseInt(specialholiday) +
        parseInt(allowanceday) +
        parseInt(others) +
        parseInt(grosspay) +
        parseInt(absent) + 
        parseInt(tardiness) +
        parseInt(sss) +
        parseInt(pagibig) +
        parseInt(philhealth) +
        parseInt(cashadvances) +
        parseInt(withholdingtax) +
        parseInt(others) +
        parseInt(monthpay13);

        if (!isNaN(result)) {
            document.getElementById('totalincome').value = result;
        }
        }

Answer 1

问题是您对字段6和字段16使用相同的ID others。为它们提供不同的ID

16.<input type="text" id="others1" Placeholder="More others"  onkeyup="sum();" /><br>

改变JS：

var others1 = var others = document.getElementById('others1').value;

var result = 

parseInt(basicpay) + 
parseInt(overtime) +
parseInt(regularholiday) +
parseInt(specialholiday) +
parseInt(allowanceday) +
parseInt(others) +
parseInt(grosspay) +
parseInt(absent) + 
parseInt(tardiness) +
parseInt(sss) +
parseInt(pagibig) +
parseInt(philhealth) +
parseInt(cashadvances) +
parseInt(withholdingtax) +
parseInt(others1) +
parseInt(monthpay13);

Answer 2

我认为该问题是因为您的6和16号码文本框具有相同的ID。

更改文本框号16的ID，它应该有效。

Answer 3

问题发生在最后一个字段上。这是因为您有两个具有相同ID的框。要修改该更改，请输入最后一个框ID from others to others2。并且还将名为others的变量更改为其他2，因为有两个变量称为others

另外，使用Javascript函数添加多个文本框
