Methods
迭代集合的元素,返回谓词,返回truthy的所有元素的数组。谓词用三个参数调用:(value,index | key,collection)。
注意: 与_.remove
此不同,此方法返回一个新数组。
0.1.0
collection
(Array | Object):迭代的集合。 [predicate=_.identity]
(Function):每次迭代调用的函数。 (Array):返回新的过滤数组。
var users = [ { 'user': 'barney', 'age': 36, 'active': true }, { 'user': 'fred', 'age': 40, 'active': false } ]; _.filter(users, function(o) { return !o.active; }); // => objects for ['fred'] // The `_.matches` iteratee shorthand. _.filter(users, { 'age': 36, 'active': true }); // => objects for ['barney'] // The `_.matchesProperty` iteratee shorthand. _.filter(users, ['active', false]); // => objects for ['fred'] // The `_.property` iteratee shorthand. _.filter(users, 'active'); // => objects for ['barney']
