javascript - 如何在 JavaScript 中将数组中的随机值分配给另一个数组中的项目(将名称数组分配给工作日数组)？

Question

我有以下工作日数组:

var weekDays = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"];

还有另一组员工:

var empl = ["Bill Smith", "Bob Brown", "Megan Stallion", "Seth Evermann", "Kelly Swartz", "Mike Belltooth"]; 

第二个阵列的员工必须在第一个阵列的其中一天工作，例如周一:比尔·史密斯等。

到目前为止我所拥有的是:

var weekDays = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]; 

for (var i = 0; i < weekDays.length; i++){
var empl = ["Bill Smith", "Bob Brown", "Megan Taylor", "Seth Evermann", 
"Kelly Swartz", "Mike Woods"];

console.log( "Day: " + i + ";" + " Shift: " + 
empl[Math.floor(Math.random()*empl.length)] + ";" );
}

结果是这样的:

Day: 0; Shift: Megan Taylor;
Day: 1; Shift: Mike Woods;
Day: 2; Shift: Seth Evermann;
Day: 3; Shift: Bill Smith;
Day: 4; Shift: Bill Smith;
Day: 5; Shift: Bill Smith;

但我需要它是 Day: Mon、Day: Tue、Day: Wed 等，而不是 Day: 0、Day: 1 等。

此外，我希望每个名字只能使用一次，这样每个人只能在其中一天工作。

结果应该是这样的:

Day: Mon; Shift: Bob Brown; 
Day: Tue; Shift: Megan Taylor; 
Day: Wed; Shift: Bill Smith; 
...

我非常感谢对此的任何帮助，谢谢。

你就快到了。使用 for of 语法和 splice:

var weekDays = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]; 
var empl = ["Bill Smith", "Bob Brown", "Megan Taylor", "Seth Evermann", "Kelly Swartz", "Mike Woods"];

for (var i of weekDays){
  console.log( 
    "Day: " + i + ";" + " Shift: " + 
    empl.splice(Math.random()*empl.length|0, 1) + ";" 
  );
}
