使用lodash在对象中查找属性的部分名称

Question

我有一个看起来像这样的对象：

var user = {
 "user_number12": "1234",
 "user_number14": "1235",
 "email": "joe@yahoo.com"
}

我想通过搜索属性字符串找到所有用户＆＃34; user_number＆＃34;用lodash。

_.has(_.includes(user, "user_number"))

不起作用。我只是想知道如何将_.ha和_.includes

连在一起

Answer 1

您可以使用_.pickBy。它返回一个对象，其中包含谓词为其返回truthy值的所有属性。您可以在谓词中使用_.includes()。

var user = {
 "user_number12": "1234",
 "user_number14": "1235",
 "email": "joe@yahoo.com"
}
var newUser = _.pickBy(user, (value, key) => _.includes(key, "user_number"))
console.log(newUser);
