将对象数组展平为单个数组

Question

我有一个带动态键的对象数组

response = [{"1": 1}, {"2": 1}, {"3": 1}, {"4": 0}, {"5": 0}];

我想将这个对象数组展平为一个数组

Output = [1, 1, 1, 0, 0]

我尝试了以下方法:

const test2 = this.response.map(obj => {
    Object.keys(obj).map(function(key){
        return obj[key]
    })
});

const test = this.response.reduce(function(prev, curr){
    console.log(curr)
    return (curr) ? prev.concat(curr): prev;
},[]);

Answer 1

您可以使用map和object.values

response = [{"1": 1}, {"2": 1}, {"3": 1}, {"4": 0}, {"5": 0}]
const vals = response.map(o => Object.values(o)[0])

console.log(vals)

Answer 2

你可以用.map()与.concat():

let data =   [{"1": 1}, {"2": 1}, {"3": 1}, {"4": 0}, {"5": 0}];
      
let result = [].concat(...data.map(Object.values));

console.log(result);
