javascript vue.js object 配列を検索

Posted at

vue.jsで配列を検索したい。
しかし、なぜか find を使うと googlebot が エラーを吐く。
これはSEO的にまずい。

ということで、 filter を使って要素を取得したり、存在チェックしたりします。

まずは元になるデータ


var arr = [
    {
        id:100,
        name: '一郎',
        age: 25
    },
    {
        id:102,
        name: '二郎',
        age: 21
    },
    {
        id:153,
        name: '三郎',
        age: 18
    }
];


ID153のデータはある?


var tmp = arr.filter(e => e.id == 153);

if(tmp.length > 0){
    console.log("ID153のデータはあります");
} else {
    console.log("ユーザーが見つかりません");
}


データを絞り込む


//指定した条件のデータを抽出
var tmp = arr.filter(e => e.age >= 20);

// 結果
// 0: {id: 100, name: "一郎", age: 25}
// 1: {id: 102, name: "二郎", age: 21}
