Question

我有一个多维数组，如下所示：

products = '[["A","Apple","20","apple.html"],["B","Banana","13","banana.html"],["C","Cereal","45","cereal.html"],["D","Dishes","320","dishes.html"]]';

我试图将其转换为JSON对象（至少我认为格式是什么），但只有索引1和3 ......所以产品[0] [1]，产品[0] [3]。这就是我的结果需要看起来的样子。

pList = [{value: 'Apple', data: 'apple.html'},{value: 'Banana', data: 'banana.html'}];

如何完成这项工作？

Answer 1

按JSON.parse将字符串解析为数组。
使用Array.prototype.map()从数组中获取值。

var products = '[["A","Apple","20","apple.html"],["B","Banana","13","banana.html"],["C","Cereal","45","cereal.html"],["D","Dishes","320","dishes.html"]]';

products = JSON.parse(products);

var pList = products.map(function(item) {
  return {
    value: item[1],
    data: item[3]
  };
});

console.log(pList);

将多维数组的内容转储到新的JSON变量中
