Question

我想这样做，以便数组中的每个项目都显示在单独的行中，但是我的“ \ n”不起作用。我放在错误的地方了吗？我尝试将其放在其他位置，但似乎没有什么不同。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

您要在数组末尾添加换行符，您需要将其添加到数组中的每个元素之间（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

尝试是否有帮助

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

尝试遍历整个数组并改为记录每个员工：

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

Answer 4

您只在输出的最后添加了\n，而您似乎希望在数组中的每个元素之后打印\n。您可以使用join方法来获得所需的结果：

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));

为什么数组中的项目没有显示在单独的行上？
