我有2个冠军的阵列。
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Championship_id的数组元素。
我的意思是,我将需要访问{{team.name}}
,在PHP中,我具有ChampionshipId的值,这意味着在代码中的任何地方,我都可以包含:championship-id= 13
。
我不知道该怎么做是选择具有Championship_id = 13的数组
还是应该更改阵列结构,以便更轻松地获得所需的团队和竞争对手?
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 protected]"
]
]
"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 protected]"
]
1 => array:2 [▼
"id" => 105
"name" => "julien2"
]
2 => array:2 [▼
"id" => 106
"name" => "[email protected]"
]
3 => array:2 [▼
"id" => 107
"name" => "[email protected]"
]
4 => array:2 [▼
"id" => 108
"name" => "[email protected]"
]
]
"teams" => array:2 [▼
0 => array:2 [▼
"id" => 4
"name" => "rr1"
]
1 => array:2 [▼
"id" => 5
"name" => "rr2"
]
]
]
]
最佳答案
Array.prototype.find
可能正是您想要的。
find()方法返回满足提供的测试功能的数组中第一个元素的值。否则返回undefined。
所以:
const arr = ...
const targetID = 13;
const championship = arr.find((elem) => elem.championship_id == targetID);
关于javascript - 选择其中Championship_id = 13的数组,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/42799447/
