我是这样解决的:

const chunks = [];
const chunkSize = 10;
for (let i = 0; i < arrayToSplit.length; i += chunkSize) {
  const tempArray = arrayToSplit.slice(i, i + chunkSize);
  chunks.push(tempArray);
}

# in coffeescript
# assume "ar" is the original array
# newAr is the new array of arrays

newAr = []
chunk = 10
for i in [0... ar.length] by chunk
   newAr.push ar[i... i+chunk]

# or, print out the elements one line per chunk
for i in [0... ar.length] by chunk
   console.log ar[i... i+chunk].join ' '

如果你正在使用下划线JS，只需使用:

var result = _.chunk(arr,elements_per_chunk)

无论如何，大多数项目已经使用下划线作为依赖项。

我认为这是ES6语法的一个很好的递归解决方案:

Const chunk =函数(数组，大小){ If (!array.length) { 返回[]; ｝ Const head = array。片(0,大小); Const tail = array.slice(size); 返回[头，…块(尾巴,大小)]; }; 块console.log(((1、2、3),2));

在JS,

const splitInChunks = (arr,n) => {
  let chunksArr = [];
  if(arr !=null && arr!= undefined){
      for(i=0; i<arr.length;i+=n){
      if(arr.length-i>=n)
          chunksArr.push(arr.slice(i,i+n))
      else
           chunksArr.push(arr.slice(i,arr.length))
  }
  return chunksArr
  }
}

整洁干净，易于理解

 let nums = [1, 2, 3, 4, 5, 6, 7, 8, 9];
 let len = nums.length ;

    const chunkArr = (arr, chunkNo) => {
      let newArr = [];
      for(let i = 0; i < len; i++){
        if(nums[0] !== "" && nums[0] !== undefined ){
          let a = nums.splice(0,chunkNo) ; 
          newArr.push(a);
        }
      }
       return newArr ;
    }
    console.log(chunkArr(nums, 5));
