实现

  1. let arr = [];
  3. for(let i=1; i<=300; i++) {
  4.     arr.push(i)
  5. }
  7. let pageData = function (arr,num) {
  8.     let newArr = [];
  9.     if(!Array.isArray(arr)) return;
  11.     if(arr.length > num) {
  12.         for(let i=0; i<arr.length; i+= num) {
  13.             newArr.push(arr.slice(i, i+num))

  16.        newArr.push(arr)
  17.     }
  19.     return newArr;
