ruby 从数组中删除一个元素 [英] ruby Remove one element from array

问题描述

我想从数组中按值删除(仅一个)元素.

I want to remove (only one) element by value from my array.

示例:

x = [1,2,3,2]
x.remove(2)


result: x= [1,3]

但是，我想得到 [1,3,2].

谢谢

推荐答案

如@7urkm3n在评论中提到的，可以使用x.delete_at删除第一次出现

As @7urkm3n mentioned in the comments, you can use x.delete_at to delete the first occurance

x.delete_at(x.index 2)

<小时>

> x = [1,2,3,2]
=> [1, 2, 3, 2] 
> x.delete_at(x.index 2)
=> 2 
> x
=> [1, 3, 2]
