使用键和值将字符串数组转换为数组 Object

Question

我想像这样转换一个字符串数组：

const arr = [
  "name:Adam age:20 height:180cm",
  "name:Sally age:30 height:170cm",
  "name:Mike age:35 height:185cm",
  "name:David age:40 height:190cm"
];

到这个包含 object 的数组，其键和值如下所示：

var obj = [
  {name:'Adam', age:20, height:'180cm'},
  {name:'Sally', age:30, height:'170cm'},
  {name:'Mike', age:35, height:'185cm'},
  {name:'David', age:40, height:'190cm'}
];

谢谢！

Answer 1

 const arr = [ "name:Adam age:20 height:180cm", "name:Sally age:30 height:170cm", "name:Mike age:35 height:185cm", "name:David age:40 height:190cm" ] let result = arr.map(e => Object.fromEntries(e.split(' ').map(n=>n.split(":")))) console.log(result)

Answer 2

您可以使用数组 map 和 split 方法来获得结果。

 const arr = [ 'name:Adam age:20 height:180cm', 'name:Sally age:30 height:170cm', 'name:Mike age:35 height:185cm', 'name:David age:40 height:190cm', ]; const ret = arr.map((x) => { const obj = {}; const a = x.split(' '); a.forEach((y) => { const [key, value] = y.split(':'); obj[key] = key === 'age'? +value: value; }); return obj; }); console.log(ret);

Answer 3

很抱歉命名不好，因为我很匆忙，但这样的事情应该会有所帮助：

 s = "name:Adam age:20 height:180cm"; a = s.split(" "); c = a.map(item => { pair = item.split(":"); key = "\"" + pair[0] + "\""; value = "\"" + pair[1] + "\""; return key + ":" + value; }); s = c.join(","); s = "{" + s + "}"; o = JSON.parse(s); console.log(o)

最后o应该是您想要的 object。
