如何基於數組的值過濾數組的數組

Question

我有兩個數組playerMoves和movesList 。 像這樣。

var playerMoves= [4, 6];
var movesList= [[0,1,2],[0,3,6]];

我需要過濾movesList陣列，使得值playerMoves陣列不應存在的每個陣列中movesList 。

console.log(move);
// should return [0,1,2]

我的嘗試

var playerMoves= [4, 6];
var movesList= [[0,1,2],[0,3,6]];
var move =  movesList.filter(v => v.filter(c => {
   return playerMoves.indexOf(c) === -1;
}));
console.log(move);

Answer 1

您可以混合使用Array#filter ， Array#every和Array#includes 。

 let playerMoves = [4, 6]; let movesList = [ [0, 1, 2], [0, 3, 6], [5, 7, 9], ]; let res = movesList.filter(v => v.every(c => !playerMoves.includes(c))); console.log(JSON.stringify(res));
