我想传入以下数组的后三个值,并分别写入三个数组0 : (4) [0.625, 5, 0, 3] 1 : (4) [0.545455, 6, 0, 5] 2 : (4) [0.5, 3, 0, 3] 3 : (4) [0.5, 3, 0, 3] 4 : (4) [0.428571, 3, 0, 4] 5 : (4) [0.428571, 3, 1, 3] 6 : (4) [0.25, 2, 1, 5] 7 : (4) [0.230769, 3, 0, 10] 8 : (4) [0.222222, 4, 0, 14] 9 : (4) [0.2, 2, 0, 8],我已写出代码但无法实现,请帮我改正并优化:this.movieService.good_directors().subscribe((data: any[]) => { this.movies = data; console.log(this.movies) const director = Object.keys(data) const count = Object.values(data) console.log(count) let index const a = [] const b = [] const c = [] for (index in count){ a.push(index[1]) b.push(index[2]) c.push(index[3]) console.log(a,b,c) }
