javascript - 如何过滤数组数组

Question

我有这样的数组:

homeShapeShift: [
        [
            {text:"BTC", callback_data: 'btc'},
            {text:"ETH", callback_data: 'eth'},
            {text:"XRP", callback_data: 'xrp'},
            {text:"ETC", callback_data: 'etc'},
        ],
        [
            {text:"ZEC", callback_data: 'zec'},
            {text:"DASH", callback_data: 'dash'},
            {text:"LTC", callback_data: 'ltc'},
            {text:"OMG", callback_data: 'omg'},
        ],
                [
            {text:"ADA", callback_data: 'ada'},
            {text:"BTG", callback_data: 'btg'},
            {text:"TRX", callback_data: 'trx'},
            {text:"NEO", callback_data: 'neo'},
        ],
    ]

如何删除带有文本 Zec 的对象并在没有它的情况下接收新数组？
我用过滤器尝试了一些东西，但没有收到好的结果

let fe = keyboard.homeShapeShift.filter(k => k.filter(e => e.text !== 'ZEC'));

Answer 1

如果您只想删除一个元素，只需将内部数组映射到新的内部过滤数组:

  let fe = keyboard.homeShapeShift.map(k => k.filter(e => e.text !== 'ZEC'));

或者，如果您想删除整个数组，请使用 every得到一个 bool 值:

 let fe = keyboard.homeShapeShift.filter(k => k.every(e => e.text !== 'ZEC'));

也可以用 some 反转:

 let fe = keyboard.homeShapeShift.filter(k => !k.some(e => e.text === 'ZEC'));
