Javascript返回并映射到对象

我有一个对象,我想返回两个值并将它们映射到一个对象.

宾语

Itemlist:[
{name: 'Chicken', searchParam: 'chicken', search: true},
{name: 'table', searchParam: 'table', search: false},
{name: 'books', searchParam: 'books', search: true}]

想从Itemlist searchParam返回并搜索并映射到一个结果将是的对象:

{chicken: true},{table: false},{books: true},

所以回归会是这样的

{ Itemlist[0].searchParam :Itemlist[0].search }

您可以使用array#map获得包含对象的数组name,并search从ITEMLIST的每个对象的价值.

var itemlist = [{name: 'Chicken', searchParam: 'chicken', search: true},{name: 'table', searchParam: 'table', search: false},{name: 'books', searchParam: 'books', search: true}];

var result = itemlist.map(({searchParam, search}) => ({[searchParam]: search}));
console.log(result);

var itemlist = [{name: 'Chicken', searchParam: 'chicken', search: true},{name: 'table', searchParam: 'table', search: false},{name: 'books', searchParam: 'books', search: true}];

var result = itemlist.map(function(item) {
  var obj = {};
  obj[item.searchParam] = item.search;
  return obj;
});
console.log(result);

var itemlist = [{name: 'Chicken', searchParam: 'chicken', search: true},{name: 'table', searchParam: 'table', search: false},{name: 'books', searchParam: 'books', search: true}];

var result = itemlist.map(({searchParam, search}) => ({[searchParam]: search}));
console.log(result);
