<!DOCTYPE HTML>
<html lang="en-us">
<head>
    <meta charset="utf-8">
    <title>5 Times Table</title>
    <script type="text/javascript">
         /* Program to print the five times table from 1 to 12 in this format:
         5 x 1 = 5
         5 x 2 = 10
         5 x ...
         Input: There will be no user input, program will use a loop to create the 5 times table.
         Process: Define all the 5 times table between 1 and 12.
         Output: The 5 times table will be displayed.
         */
        function fiveTimesTable() {
            var result = 0;
            for (i=1; i<=12; i++){
                 result = "5 * " + i + result + i*5 + "<br>";
            var display =result;
            }
            document.getElementById("outputDiv").innerHTML = display;

你的代码很接近，但如果你把它分成几个部分会更容易理解。

function fiveTimesTable() {
  var display = ""; // The table output HTML

  for (i = 1; i <= 12; i++) {
     var multiplier = 5;
     var result = i*5;

     display += multiplier+" * "+i+" = "+result+"<br>"; //Add each line to our output HTML
  }

  document.getElementById("outputDiv").innerHTML = display;
}

快来看in this codepen。
如果你感兴趣的话，我们会面临一些挑战。
1.使函数能够显示使用参数的任何乘数的表。
1.把你的表格放到一个实际的HTML表格元素中。
