sortedLastIndexBy

_.sortedLastIndexBy(array, value, [iteratee=_.identity])

此方法类似于 _.sortedLastIndex，只是它接受 iteratee，后者为 value 和 array 的每个元素调用以计算它们的排序排名。迭代器使用一个参数调用：(value)。

¥This method is like _.sortedLastIndex except that it accepts iteratee which is invoked for value and each element of array to compute their sort ranking. The iteratee is invoked with one argument: (value).

参数

¥Arguments

1. array (数组)：要检查的排序数组。

   ¥array (Array): The sorted array to inspect.

2. value (*):要评估的值。

   ¥value ()*: The value to evaluate.

3. [iteratee=_.identity] (函数)：每个元素调用迭代器。

   ¥[iteratee=_.identity] (Function): The iteratee invoked per element.

返回

¥Returns

(数值)：返回应将 value 插入 array 的索引。

¥(number): Returns the index at which value should be inserted into array.

示例

¥Example

var objects = [{ 'x': 4 }, { 'x': 5 }];

_.sortedLastIndexBy(objects, { 'x': 4 }, function(o) { return o.x; });
// => 1

// The `_.property` iteratee shorthand.
_.sortedLastIndexBy(objects, { 'x': 4 }, 'x');
// => 1
