我想在幾個公式中添加一個名爲Calc()的函數。我設法完成了總時間和標準時間的計算。按照以下公式，我需要幫助來添加計算。HTML - 函數中的多次計算
- 贏取小時=
stdHour*表數 - 人們=（賺小時/ 6.6）*天數
- 賺取天= /（計數頭數/
stdHour）表數
注意：表格的數量，天數和人數是用戶輸入。
function findSum() {
var hour = 6.6;
var shift = 3.0;
document.getElementById('capacity').value = Math.round(hour * shift);
}
function Calc() {
//I want to add the variable of `earnHour`, `people` and `earnDays` here
let arr = document.getElementsByName('qty');
let tot = 0;
for (let i = 0; i < arr.length; i++) {
let radios = document.getElementsByName("group" + (i + 1));
for (let j = 0; j < radios.length; j++) {
let radio = radios[j];
if (radio.value == "Yes" && radio.checked) {
tot += parseInt(arr[i].value);
}
}
}
document.getElementById('total').value = Math.round(tot);
var stdHour = document.getElementById('stdHour').value = ((tot * 1.15)/60);
//I do not know how to reference the input box values from `HTML` to here.

什麼是你所遇到的問題？您現有的函數演示瞭如何獲取/設置輸入元素值以及如何使用'*'，'/'等進行計算。您提到的三種公式是不是相同？ – nnnnnn
@nnnnnn我需要幫助在Calc（）函數中添加這些計算。我做了他們，但沒有奏效。 – cerberus99
@JaromandaX是的，我擔心以前提出的問題不是直接的。任何想法如何解決這個問題？ – cerberus99
