array
(Array):要查询的数组。 [predicate=_.identity]
(Function):每次迭代调用的函数。 (数组):返回部分array
。
var users = [ { 'user': 'barney', 'active': false }, { 'user': 'fred', 'active': false }, { 'user': 'pebbles', 'active': true } ]; _.dropWhile(users, function(o) { return !o.active; }); // => objects for ['pebbles'] // The `_.matches` iteratee shorthand. _.dropWhile(users, { 'user': 'barney', 'active': false }); // => objects for ['fred', 'pebbles'] // The `_.matchesProperty` iteratee shorthand. _.dropWhile(users, ['active', false]); // => objects for ['pebbles'] // The `_.property` iteratee shorthand. _.dropWhile(users, 'active'); // => objects for ['barney', 'fred', 'pebbles']
