matchesProperty

js
_.matchesProperty(path, srcValue)

创建一个函数,对给定对象的 path 值和 srcValue 进行部分深度比较,如果对象值等效,则返回 true,否则返回 false

¥Creates a function that performs a partial deep comparison between the value at path of a given object to srcValue, returning true if the object value is equivalent, else false.

注意:部分比较将分别将空数组和空对象 srcValue 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

¥Note: Partial comparisons will match empty array and empty object srcValue 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

_.find(objects, _.matchesProperty('a', 4));

// Checking for several possible values
_.filter(objects, _.overSome([_.matchesProperty('a', 1), _.matchesProperty('a', 4)]));
