尝试在函数中创建多维数组

Question

我目前正在尝试采用3个单独的输入，并将它们转换为多维数组。

我知道用户最多可以输入8个输入，但是我当前的代码会打印出空数组。我正在寻找一种动态创建我编写的代码的方法，以避免出现此问题。下面是我制作的函数的副本。

a = 'Hi' 

b = 878

c = 654

function exitToTable(a, b, c) {

            for (var i = 0; i < 8; i++) {

                tester[i] = new Array(8);

            }

            tester[0][0] = a[0];

            tester[0][1] = b[0];

            tester[0][2] = c[0];

            tester[1][0] = a[1];

            tester[1][1] = b[1];

            tester[1][2] = c[1];

            tester[2][0] = a[2];

            tester[2][1] = b[2];

            tester[2][2] = c[2];

            tester[3][0] = a[3];

            tester[3][1] = b[3];

            tester[3][2] = c[3];

            tester[4][0] = a[4];

            tester[4][1] = b[4];

            tester[4][2] = c[4];

            tester[5][0] = a[5];

            tester[5][1] = b[5];

            tester[5][2] = c[5];

            tester[6][0] = a[6];

            tester[6][1] = b[6];

            tester[6][2] = c[6];

            tester[7][0] = a[7];

            tester[7][1] = b[7];

            tester[7][2] = c[7];

            for (var i = 0; i < 8; i++) {

                for (var j = 0; j < 3; j++) {

                    document.write(tester[i][j] + '&emsp;');

                }

                document.write('</br>');

            }

        }

我希望数组在a ='Hi'b = 878 c = 654时输出如下

但是请注意，“ a”，“ b”和“ c”都是存储自己的数据的数组。a中的每个元素都是一个字符串，b和c中的每个元素都是整数。

嗨878654

嗨878654

嗨878654

等等....

Answer 1

在雇主的脑力激荡中，我的想法是：我将自己的工作推向正确的方向，如下所示：function generateTable(a, b, c) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; document.write('<table cellspacing="5" cellpadding="1" border="1"><tr><th>State/Teritory</th><th>population</th><th>Growth Rate</th></tr>')&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; for (var i = 0; i < a.length; i++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; document.write('<tr><td>' + a[i] + '</td><td>' + b[i] + '</td><td>' + c[i] + '</td></tr>');&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; document.write('</table><br><hr>');&nbsp; &nbsp; &nbsp; &nbsp; }

Answer 2

这应该给您您期望的结果：const a = ['Hi', 'Hi', 'g', 'j', 'm', 'p', 's', 'v'];const b = ['900', '900', 'h', 'k', 'n', 'q', 't', 'w'];const c = ['654', '654', 'i', 'l', 'o', 'r', 'u', 'x'];function exitToTable(a, b, c) {&nbsp; let length = a.length;&nbsp; if (length !== b.length || length !== c.length) {&nbsp; &nbsp; console.warn('arrays must be of same length');&nbsp; }&nbsp; [...Array(length)].map((_, index) => {&nbsp; &nbsp; document.write(`${[a[index], b[index], c[index]].join('&emsp;')}<br/>`);&nbsp; });}exitToTable(a, b, c);
