Boolean 比较在 if 条件下不起作用 angular 离子

Question

carSeat是复选框输入，其值可以是true或false ，我使用console.log检查了它的值并且它显示了正确的值，但它不会 go 进入 if 条件。

if (this.carSeat == true) {
  this.YesOrNo = "Yes";
  if (this.typeCar == "Sedan") {
    console.log(` if condition : ${this.carSeat} `);
    this.Subtotal =
      this.sedanHourlyRate * this.hours +
      this.sedanFlatRate * this.days +
      this.carSeatHorlyFlatRate * this.hours +
      this.carSeatDailyFlatRate * this.days;
    this.SalesTax = (this.Subtotal * 13) / 100;
    this.total = this.Subtotal + this.SalesTax;
  }
  if (this.typeCar == "SUV") {
    this.Subtotal =
      this.suvHourlyRate * this.hours +
      this.suvFlatRate * this.days +
      this.carSeatHorlyFlatRate * this.hours +
      this.carSeatDailyFlatRate * this.days;
    this.SalesTax = (this.Subtotal * 13) / 100;
    this.total = this.Subtotal + this.SalesTax;
  }
}
if (this.carSeat == false) {
  this.YesOrNo = "No";
  if (this.typeCar == "Sedan") {
    this.Subtotal =
      this.sedanHourlyRate * this.hours + this.sedanFlatRate * this.days;
    this.SalesTax = (this.Subtotal * 13) / 100;
    this.total = this.Subtotal + this.SalesTax;
  }
  if (this.typeCar == "SUV") {
    this.Subtotal =
      this.suvHourlyRate * this.hours + this.suvFlatRate * this.days;
    this.SalesTax = (this.Subtotal * 13) / 100;
    this.total = this.Subtotal + this.SalesTax;
  }
}

我试过===而不是== ，但它仍然没有进入 if 条件。

我认为你的问题是 bool 的值是字符串

试试this.carSeat == 'true'
