1,我想把一個(gè)數(shù)組按照3等分合成一個(gè)新數(shù)組把這個(gè)數(shù)組vararr=[["12"],["blob:http://localhost:8090/a23268b6-dde4-4ae8-a845-3fc0bc9c4ef8"],["12","12"],["12"],["blob:http://localhost:8090/a23268b6-dde4-4ae8-a845-3fc0bc9c4ef8"],["12","12"]]變成vararr=[arr1,arr2]=[[["12"],["blob:http://localhost:8090/a23268b6-dde4-4ae8-a845-3fc0bc9c4ef8"],["12","12"]],[["12"],["blob:http://localhost:8090/a23268b6-dde4-4ae8-a845-3fc0bc9c4ef8"],["12","12"]]]給個(gè)方法，急！3Q3Q？
怎么從一個(gè)數(shù)組獲得新數(shù)組？
