JS：数组中最大的元素，小于给定的变量(JS : Biggest element of an array, less than a given variable)

JS：数组中最大的元素，小于给定的变量(JS : Biggest element of an array, less than a given variable)

鉴于：

var array = [1,2,5,10]; var limit = 8;

我正在寻找一种方法来找到数组中最大的元素，小于极限8。

Math.max(array, "while < limit");

我试过了 ：

Math.min(Math.max(array), limit)

这在所有情况下都不适用于数组和限制，显然。

编辑：

输入数组不一定排序：

var array = [10,-10,10,-10]; var limit = 5;

预期的结果是-10。

Given :

var array = [1,2,5,10]; var limit = 8;

I am looking for a way to find the biggest element of the array, less than the limit 8. something like :

Math.max(array, "while < limit");

I tried :

Math.min(Math.max(array), limit)

which does not work in all cases for array and limit, obviously.

EDIT :

The input array is not necessarily sorted :

var array = [10,-10,10,-10]; var limit = 5;

Expected result is -10.

最满意答案

var array = [1,2,5,10];
var limit = 8;
alert(Math.max.apply(Math, array.filter(function(x){return x <= limit}))); 
  
 
 
 
  
  
var array = [1,2,5,10];
var limit = 8;
alert(Math.max.apply(Math, array.filter(function(x){return x <= limit})));
