为什么我的数组中的项目不显示在单独的行中？

Question

我想要这样做，所以我的数组中的每个项目都显示在不同的行上，但我的“\ n”不起作用。我把它放在错误的地方吗？我试图把它放在其他地方，但似乎没有什么区别。我的功能目标是遍历数组。

var employees = [];
employees[0] = "Zak";
employees[1] = "Jessica";
employees[2] = "Mark";
employees[3] = "Fred";
employees[4] = "Sally";

var showEmployee = function (names) {
    'use strict';
    showEmployee = employees;
    return names;
};

showEmployee(employees);
window.console.log(showEmployee + "\n");

Answer 1

您在数组末尾添加换行符，需要在数组中的每个元素之间添加换行符（使用join）

var employees = [];
employees[0] = "Zak";
employees[1] = "Jessica";
employees[2] = "Mark";
employees[3] = "Fred";
employees[4] = "Sally";

var showEmployee = function (names) {
    'use strict';
    showEmployee = employees;
    return names;
};

showEmployee(employees);
window.console.log(showEmployee.join("\n"));

Answer 2

试试这是否有帮助

var employees = [];
employees[0] = "Zak";
employees[1] = "Jessica";
employees[2] = "Mark";
employees[3] = "Fred";
employees[4] = "Sally";

var showEmployee = function (names) {
  names.map((name) => window.console.log(name));
};

showEmployee(employees);

Answer 3

你只是在输出的最后添加\n，而你似乎期望在数组中的每个元素之后打印\n。您可以使用join方法获得所需的结果：

var employees = [];
employees[0] = "Zak";
employees[1] = "Jessica";
employees[2] = "Mark";
employees[3] = "Fred";
employees[4] = "Sally";

function showEmployee(a) {
  return a.join(',\n')
}

console.log(showEmployee(employees));

Answer 4

尝试循环遍历您的阵列并记录每个员工：

employees.forEach(function(employee) {
    console.log(employee)
})
