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

Question

我有一周的工作日：

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

另一组员工：

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

来自第二阵列的雇员必须在第一阵列的一天工作，例如星期一：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)] + ";" );
}

这导致了这样的事情：

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;

但是我需要它是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，所以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; 
...

我真的很感激任何帮助，谢谢。

Answer 1

你快到了。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) + ";" 
  );
}

Answer 2

你只是缺少一段代码。

你：

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

更新：

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