Javascript 数组以连续数字等开头单词进行分割

Question

你能帮我吗？我有一个名为 baseArray 的数组。正如您所看到的一些值是相同的，我尝试删除重复的值，但没有完全起作用。

然后我尝试分割数组，例如

[[1,2,3,4,5,6,7], [1,2,4,5,6,7], [1,2,3,4,5,6,7,8,9,10..]..]

我想分割以数字 1 开头的每个数字系列

const editedArray = [];

const baseArray = [1, 2, 3, 4, 5, 6, 7, 7, 7, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 1,
    2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 12, 12, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7,
    7, 8, 8, 9, 9, 10, 10, 11, 11, 12, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,
    13, 13, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10, 11, 11, 12,
    12, 13, 13, 1, 2, 3, 4, 5, 6, 6, 6, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 1, 2, 3, 4,
    5, 6, 7, 8, 9, 10, 10, 10, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10,
    10, 1, 2, 3, 4, 5, 6, 6, 6, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 1, 2, 3, 4, 5, 6, 7,
    8, 9, 9, 9, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 1, 2, 3, 4, 5, 6,
    7, 8, 9, 10, 10, 10, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10,
    1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 11, 11, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7,
    8, 8, 9, 9, 10, 10, 11, 11, 1, 2, 3, 4, 5, 5, 5, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5
]
baseArray.filter(function (item, pos) {
    return baseArray.indexOf(item) == pos;
})

baseArray.forEach(item => item === 1 ?
    editedArray.push([1]) :
    editedArray[editedArray.length - 1].push(item)
)

console.log(editedArray)

这给了我这样的结果 enter image description here

已更新，现在可以正常使用了

const editedArray = [];

const baseArray = [1, 2, 3, 4, 5, 6, 7, 7, 7, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 1,
    2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 12, 12, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7,
    7, 8, 8, 9, 9, 10, 10, 11, 11, 12, 12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13,
    13, 13, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10, 11, 11, 12,
    12, 13, 13, 1, 2, 3, 4, 5, 6, 6, 6, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 1, 2, 3, 4,
    5, 6, 7, 8, 9, 10, 10, 10, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10,
    10, 1, 2, 3, 4, 5, 6, 6, 6, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 1, 2, 3, 4, 5, 6, 7,
    8, 9, 9, 9, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 1, 2, 3, 4, 5, 6,
    7, 8, 9, 10, 10, 10, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10,
    1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 11, 11, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7,
    8, 8, 9, 9, 10, 10, 11, 11, 1, 2, 3, 4, 5, 5, 5, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5
]
var result = baseArray.filter((a, i, aa) => a !== aa[i + 1]);

result.forEach(item => item === 1 ?
    editedArray.push([1]) :
    editedArray[editedArray.length - 1].push(item)
)
console.log(editedArray)

Answer 1

使用Array#reduce

const baseArray = [1,2,3,4,5,6,7,7,7,1,1,2,2,3,3,4,4,5,5,6,6,7,7,1,2,3,4,5,6,7,8,9,10,11,12,12,12,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,1,2,3,4,5,6,7,8,9,10,11,12,13,13,13,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,1,2,3,4,5,6,6,6,1,1,2,2,3,3,4,4,5,5,6,6,1,2,3,4,5,6,7,8,9,10,10,10,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,1,2,3,4,5,6,6,6,1,1,2,2,3,3,4,4,5,5,6,6,1,2,3,4,5,6,7,8,9,9,9,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,1,2,3,4,5,6,7,8,9,10,10,10,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,1,2,3,4,5,6,7,8,9,10,11,11,11,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,1,2,3,4,5,5,5,1,1,2,2,3,3,4,4,5,5];

const editedArray = baseArray.reduce((acc, num, i, arr) => {
  if (arr[i - 1] !== num) {
    if (num === 1) acc.push([num]);
    else acc[acc.length - 1].push(num);
  }
  
  return acc;
}, []);

console.log(editedArray);
