matches

js
_.matches(source)

创建一个函数,对给定对象和 source 进行部分深度比较,如果给定对象具有等效属性值,则返回 true,否则返回 false

¥Creates a function that performs a partial deep comparison between a given object and source, returning true if the given object has equivalent property values, else false.

注意:创建的函数相当于部分应用了 source_.isMatch

¥Note: The created function is equivalent to _.isMatch with source partially applied.

部分比较将分别将空数组和空对象 source 值与任何数组或对象值进行匹配。有关支持的值比较的列表,请参阅 _.isEqual

¥Partial comparisons will match empty array and empty object source values against any array or object value, respectively. See _.isEqual for a list of supported value comparisons.

注意:可以通过使用 _.overSome 组合多个匹配器来检查多个值

¥Note: Multiple values can be checked by combining several matchers using _.overSome

];

_.filter(objects, _.matches({ 'a': 4, 'c': 6 }));
// => [{ 'a': 4, 'b': 5, 'c': 6 }]

// Checking for several possible values
_.filter(objects, _.overSome([_.matches({ 'a': 1 }), _.matches({ 'a': 4 })]));
// => [{ 'a': 1, 'b': 2, 'c': 3 }, { 'a': 4, 'b': 5, 'c': 6 }]
