假设我们有一个这样的数组数组-
const arr = [ [ ['juice', 'apple'], ['maker', 'motts'], ['price', 12] ], [ ['juice', 'orange'], ['maker', 'sunkist'], ['price', 11] ] ];
我们需要编写一个JavaScript函数,该函数接受一个这样的数组,并返回基于输入数组构建的新对象数组。
因此,对于上述数组,输出应如下所示:
const output = [ {juice: 'apple', maker: 'motts', price: 12}, {juice: 'orange', maker: 'sunkist', price: 11} ];
为此的代码将是-
const arr = [ [ ['juice', 'apple'], ['maker', 'motts'], ['price', 12] ], [ ['juice', 'orange'], ['maker', 'sunkist'], ['price', 11] ] ]; const arrayToObject = arr => { let res = []; res = arr.map(list => { return list.reduce((acc, val) => { acc[val[0]] = val[1]; return acc; }, {}); }); return res; }; console.log(arrayToObject(arr));
输出结果
控制台中的输出-
[ { juice: 'apple', maker: 'motts', price: 12 }, { juice: 'orange', maker: 'sunkist', price: 11 } ][ { juice: 'apple', maker: 'motts', price: 12 }, { juice: 'orange', maker: 'sunkist', price: 11 } ]
