如何最好地优化我的角度函数？

Question

我需要你的帮助，我有一个代码，我需要优化它，有人知道这是怎么回事吗？这是我的代码：

handlerChangeInfo(value, fieldName: string) {
if (fieldName === 'fullName') {
  this.billingFields.full_name = value;
}
if (fieldName === 'address') {
  this.billingFields.address = value;
}
if (fieldName === 'postalCode') {
  this.billingFields.postal_code = value;
}
if (fieldName === 'city') {
  this.billingFields.city = value;
}
if (fieldName === 'stateOrProvince') {
  this.billingFields.state_or_province = value;
}
if (fieldName === 'taxId') {
  this.billingFields.tax_id = value;
}

}

Answer 1

您可以创建一个对象来将字段名称值映射到对象键名称

const obj = {
  fullName: 'full_name',
  address: 'address',
  postalCode: 'postal_code',
  city: 'city',
  stateOrProvince: 'state_or_province',
  taxId: 'tax_id'
}


handlerChangeInfo(value, fieldName: string) {
   if (obj[fieldName]) {
      this.billingFields[obj[fieldName]] = value;
   }
}
