javascript - 选择冠军id = 13 的数组

Question

我有一个拥有 2 个冠军的数组。

每个冠军都有自己的球队和竞争对手

我应该如何选择具有我需要的冠军id的数组元素。

我的意思是我需要访问 {{team.name}} ，在 PHP 中，我有锦标赛 ID 值，我的意思是在代码中的任何位置，我可以包含 :championship -id=13.

我不知道该怎么做是选择冠军id=13的数组

或者我应该改变我的数组结构，以便更容易找到我需要的团队和竞争对手？

这是我的数组的结构

   array:2 [▼
0 => array:3 [▼
  "championship" => 13
  "competitors" => array:1 [▼
    0 => array:2 [▼
      "id" => 104
      "name" => "email@email.com"
    ]
  ]
  "teams" => array:3 [▼
    0 => array:2 [▼
      "id" => 1
      "name" => "t1"
    ]
    1 => array:2 [▼
      "id" => 2
      "name" => "t2"
    ]
    2 => array:2 [▼
      "id" => 3
      "name" => "t3"
    ]
  ]
]
1 => array:3 [▼
  "championship" => 15
  "competitors" => array:5 [▼
    0 => array:2 [▼
      "id" => 104
      "name" => "email@email.com"
    ]
    1 => array:2 [▼
      "id" => 105
      "name" => "julien2"
    ]
    2 => array:2 [▼
      "id" => 106
      "name" => "email@email.com2"
    ]
    3 => array:2 [▼
      "id" => 107
      "name" => "email@email.com2"
    ]
    4 => array:2 [▼
      "id" => 108
      "name" => "eee@email.comw"
    ]
  ]
  "teams" => array:2 [▼
    0 => array:2 [▼
      "id" => 4
      "name" => "rr1"
    ]
    1 => array:2 [▼
      "id" => 5
      "name" => "rr2"
    ]
  ]
]

Array.prototype.find 可能就是您正在寻找的。

The find() method returns the value of the first element in the array that satisfies the provided testing function. Otherwise undefined is returned.

所以:

const arr = ...
const targetID = 13;
const championship = arr.find((elem) => elem.championship_id == targetID);
