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++) {&nbsp; &nbsp; totalEarnings = totalEarnings + earningsPerDay;&nbsp; &nbsp; document.write("<tr><td>"+ days +"</td>");&nbsp; &nbsp; document.write("<td>" + "$" + totalEarnings +"</td></tr>");}更新经过您的解释，这里有一个更好的答案：var totalEarnings = 0;for (var days = 1; days <= daysworked; days++) {&nbsp; &nbsp; todaysEarnings = Math.pow(2 , days - 1) * 0.01;&nbsp; &nbsp; totalEarnings = totalEarnings + todaysEarnings;&nbsp; &nbsp; document.write("<tr><td>"+ days +"</td>");&nbsp; &nbsp; document.write("<td>" + "$" + todaysEarnings +"</td></tr>");}document.write("<tr><td>" + "Total: $" + totalEarnings +"</td></tr>");要么：document.write("<td>" + "$" + todaysEarnings +"</td><td>" + totalEarnings + "</td></tr>");
