過濾對象數組的對象

Question

 Objects:[
  {id:'a',
   owner: 'b',
   products:[{productId:'a1',name:'b1'},{productId:'a2',name:'b2'}]
   date: '2-2'},

  {id:'e',
   owner: 'f',
   products:[{productId:'a3',name:'b3'},{productId:'a4',name:'b4'}]
   date: '1-1'}
 ]

在上面的示例中，如何通過 name:'b3' 的值獲取第二個對象？ 名稱是產品數組的屬性，產品是對象數組的屬性。 如果有人可以幫助我，我將不勝感激。

要根據產品列表的“名稱”屬性搜索項目，您可以執行以下操作：

 const Objects = [ {id:'a', owner: 'b', products:[{productId:'a1',name:'b1'},{productId:'a2',name:'b2'}], date: '2-2'}, {id:'e', owner: 'f', products:[{productId:'a3',name:'b3'},{productId:'a4',name:'b4'}], date: '1-1' } ] const hasProductsByName = (products) => { return products.some(product => product.name == searchValue); } const searchValue = "b3"; const result = Objects.filter(obj => hasProductsByName(obj.products)); console.log(result);
