javascript - 从数组内对象的字段中提取所有单词

Question

我有这个数组:

array = [{"full_name":"louis jackson","title1":"english teacher,"description":"good and nice teacher"},{"full_name":"peter carey","title1":"math teacher,"description":"bad and ugly teacher"}]

我需要获取这个数组

results = ["louis","jackson","english", "teacher",good","and","nice","teacher","peter","carey","math","teacher","bad","and","ugly","teacher"]

我已经尝试过:

results = [];
array.forEach(item => {
results.push (item.full_name.split(" "));
results.push (item.title1.split(" "));
results.push (item.description.split(" "));    
}

我只是得到多个分离的数组；谁能以正确的方式指导我？

Answer 1

我编写了一些干净的代码来为您完成这一切

array = [{"full_name":"louis jackson","title1":"english teacher","description":"good and nice teacher"},{"full_name":"peter carey","title1":"math teacher","description":"bad and ugly teacher"}]

var results = array.flatMap(obj => {
  const vals = Object.values(obj);
  return vals.flatMap(val => val.split(' '));
})

console.log(results);

Object.values 只是从每个对象的每个属性中获取值，因此您无需处理“full_name”或“title1”等键

一旦获得了值，就可以将它们按空格分开并将它们作为数组返回。

flatMap 确保如果您返回一个数组数组，它​​会将其展平 1 层。

编辑——这是一行:

var results = array.flatMap(obj => Object.values(obj).flatMap(val => val.split(' ')));
