Question

我有这样类型的数组

如何访问Viena

可能有很多城市

[{"Viena":[{"date":"2018-11-10","time":"17:45","price":599,"to_city":"Viena","wday":"saturday"},{..},{..}],{"Paris":[{..}]} ]

Answer 1

您可以使用Array.filter。

var data = [{"Viena":[{"date":"2018-11-10","time":"17:45","price":599,"to_city":"Viena","wday":"saturday"}]},{"Paris":[{"date":"2018-11-10","time":"17:45","price":599,"to_city":"Viena","wday":"saturday"}]}];
var result = data.filter(function(value){return Object.keys(value).indexOf("Viena") != -1;});
console.log(result[0]);
