javascript - 将字符串数组传递给对象方法(Javascript)

Question

目标是将一组字符串(替代教师姓名)传递给“pickSubstituteTeacher”方法并返回一名随机教师。我不知道如何将字符串数组发送到对象方法并返回随机值。

class School {
  constructor(name, level, numberOfStudents) {
    this._name = name;
    this._level = level;
    this._numberOfStudents = numberOfStudents;
  }

  static pickSubstituteTeacher(substituteTeachers) {
    let ranNum = Math.floor(Math.random()*substituteTeachers.length);
    return substituteTeachers[ranNum];
  }
}

const school1 = new School('school1', 'two', 233);


let randomTeacher = School.pickSubstituteTeacher['teacher1','teacher2','teacher3'];

console.log(randomTeacher);

Answer 1

您必须在数组两边加上括号，以表明该数组是该方法的参数。

let randomTeacher = School.pickSubstituteTeacher(['teacher1','teacher2','teacher3']);
