我试图根据另一个属性的值从对象数组中获取值。
示例对象数组：
objArray = [ { foo: 1, bar: 2}, { foo: 3, bar: 4}, { foo: 5, bar: 6} ];
我想要得到＆＃34; 1＆＃34;基于过滤＆＃34; 2＆＃34;。我不知道＆＃34; bar的位置：2＆＃34;随着数据每天都在变化，objArray可能在第二天看起来像这样：
objArray = [ { foo: 3, bar: 4}, { foo: 1, bar: 2}, { foo: 5, bar: 6} ];
我想过滤：
但我无处可去......
答案 0 :(得分：0)
您需要array.filter而不需要strict equality：
var objArray = [ { foo: 3, bar: 4}, { foo: 1, bar: 2}, { foo: 5, bar: 6} ];
var result = objArray.filter(function(e) {
return e.bar == '2'
})
console.log(result)
答案 1 :(得分：0)
当然，这不是最优雅的方式，但它有效：
temp_at_15=[];
vals=Object.values(data);
vals.forEach(function(el) {
if(Array.isArray(el))
el.forEach(function(o) {
if(o.dt_txt.includes('15:00:00'))
temp_at_15.push(o.main.temp);
});
});
console.log(temp_at_15);
演示：

答案 2 :(得分：-1)
使用JSON.parse获取价值可能会更容易一些：
j = '[ { "foo": 1, "bar": 2 }, { "foo": 3, "bar": 4 }, { "foo": 5, "bar": 6 } ]'
a = [], b = JSON.parse(j, function(key, v) { if (v.bar === 2) a.push(v.foo); return v; })
console.log( a ); console.log( b )
