我正在尝试从表格中将我的总数加在一起，但不知道如何去做

Question

我正在尝试从这段代码中将我的总数加在一起，但不知道该怎么做。这是我一直在研究的脚本，他们每天赚的钱都会翻倍。<script>    // asks for the days you worked    var daysworked = parseFloat(prompt("daysworked", "100"));//equation and table for the days worked    for (var days = 1; days <= daysworked; days++) {        document.write("<tr><td>"+ days +"</td>");        // here is specifically the equation and how i output it         document.write("<td>" + "$" + ( Math.pow(2 , days - 1)*0.01) +"</td></tr>");我应该如何计算赚取的总金额？

Answer 1

也许这会给你一个提示：

var earningsPerDay = 77;

var totalEarnings = 0;

for (var days = 1; days <= daysworked; days++) {

    totalEarnings = totalEarnings + earningsPerDay;

    document.write("<tr><td>"+ days +"</td>");

    document.write("<td>" + "$" + totalEarnings +"</td></tr>");

}

更新

经过您的解释，这里有一个更好的答案：

var totalEarnings = 0;

for (var days = 1; days <= daysworked; days++) {

    todaysEarnings = Math.pow(2 , days - 1) * 0.01;

    totalEarnings = totalEarnings + todaysEarnings;

    document.write("<tr><td>"+ days +"</td>");

    document.write("<td>" + "$" + todaysEarnings +"</td></tr>");

}

document.write("<tr><td>" + "Total: $" + totalEarnings +"</td></tr>");

要么：

document.write("<td>" + "$" + todaysEarnings +"</td><td>" + totalEarnings + "</td></tr>");
