javascript - 更改对象键和值

Question

我有来自 api 的对象数组:

"use strict";

var data = [{
  "OPEN COVER (YES or NO)": "YES"
}, {
  "OPEN COVER (YES or NO)": "NO"
}, {
  "OPEN COVER (YES or NO)": "YES"
}];
var result = [];

data.map(function (item) {
  var fixed = {};
  var keys = Object.keys(item);
  keys.map(function (key) {
    if (key === 'OPEN COVER (YES or NO)') return fixed['open_cover'] = item[key];
  });
  result.push(fixed);
});
console.log(result);

如何将值从“YES”更改为 true，将“NO”更改为 true？

Answer 1

您可以使用三进制轻松地将“YES”转换为true，将“NO”转换为false。此外，您可以使用 forEach 而不是 map:

"use strict";

var data = [{
  "OPEN COVER (YES or NO)": "YES"
}, {
  "OPEN COVER (YES or NO)": "NO"
}, {
  "OPEN COVER (YES or NO)": "YES"
}];
var result = data.reduce(function(items, item) {
  var fixed = {};
  var keys = Object.keys(item);
  keys.forEach(function(key) {
    if (key === 'OPEN COVER (YES or NO)') {
      return fixed['open_cover'] = item[key] === 'YES';
    }
  });
  items.push(fixed);
  return items;
}, []);
console.log(result);
