JavaScript 清除数组对象

Question

您好，我有一个包含对象数组的对象数组。例如，如果我的用户搜索皮革，我想知道如何将属性清空。

我的结果：

     let cars = [{
        name: 'Volvo',
        equipments: [
         { name: 'saddleries', options: [{title: 'leather'}] },
         { name: 'wheels', options: [title: 'sliver'}] },
         { name: 'motor', options: [] }]
}];

我想要这个结果：

          let cars = [{
        name: 'Volvo',
        equipments: [
         { name: 'saddleries', options: [{title: 'leather'}] },
         { name: 'wheels', options: [title: 'sliver'}] },
}];

请问如何删除我的数据？谢谢

Answer 1

检查此代码

let cars = [{
        name: 'Volvo',
        equipments: [
         { name: 'saddleries', options: [{title: 'leather'}] },
         { name: 'wheels', options: [{title: 'sliver'}] },
         { name: 'motor', options: [] }]
}];

cars.forEach((c) => {
c.equipments = c.equipments.filter(e => e.options.length !== 0);
})
console.log(cars)

试试这个：

var cars = {
  name: 'Volvo',
  equipments: [{
      name: 'saddleries',
      options: [{
        title: 'leather'
      }]
    },
    {
      name: 'wheels',
      options: [{
        title: 'sliver'
      }]
    },
    {
      name: 'motor',
      options: []
    },
    {
      name: 'handles',
      options: []
    }
  ]
};

carsCopy = Object.assign([], cars.equipments)

var count = 0

cars.equipments.forEach(function(data, index) {
  if (data.options.length === 0) {
    carsCopy.splice(index - count, 1);
    count++;
  }
})
console.log(carsCopy)
