Javascript数组包含/包含子数组 [英] Javascript array contains/includes sub array

问题描述

我需要检查一个数组是否包含另一个数组。子阵列的顺序很重要，但实际的偏移并不重要。它看起来像这样：

I need to check if an array contains another array. The order of the subarray is important but the actual offset it not important. It looks something like this:

var master = [12, 44, 22, 66, 222, 777, 22, 22, 22, 6, 77, 3]; 

var sub = [777, 22, 22]; 

所以我想知道 master 是否包含 sub 类似于：

So I want to know if master contains sub something like:

if(master.arrayContains(sub) > -1){
    //Do awesome stuff
}

那怎么样这可以用优雅/有效的方式完成吗？

So how can this be done in an elegant/efficient way?

推荐答案

想出了快速思考，但效率取决于大小数组

Just came up with quick thought , but efficiency depends on size of the array

var master = [12, 44, 22, 66, 222, 777, 22, 22, 22, 6, 77, 3];
var sub = [777, 22, 22];

if ((master.toString()).indexOf(sub.toString()) > -1 ){
    //body here
}
