比较两个数组并将不同的值推送到新数组 [英] Compare two arrays and push different values to new array

问题描述

我有两个要比较的数组，并将两个都不相同的值推送到新数组中。基本上，我试图将arrayOne中没有的arrayTwo值推到新数组中。

I have two arrays that I want to compare and push values that are not the same in both to a new array. Basically I'm trying to push values from arrayTwo that are not in arrayOne to a new array.

  var arrayOne = [[1,"121"], [2,"111"], [2,"321"], [3,"232"], [3,"213"], [4,"211"]],
  arrayTwo = [[4,"111"], [1,"131"], [3,"321"], [3,"232"], [3,"211"], [3,"213"], [1, "X1X"]];
  doNotMatch = []; 

我尝试遍历前两个数组，比较如下所示的值，但这显然行不通：

I tried looping through the first two arrays comparing the values like below but this obviously isn't working:

 for ( var i = 0; i < arrayOne.length; i++ ) {
        for ( var e = 0; e < arrayTwo.length; e++ ) {
            if ( arrayOne[i] !== arrayTwo[e]) {
                doNotMatch.push(arrayTwo[e])
                } 
        }
    }

推荐答案

var arrayOne = ["dog", "cat", "hamster", "gerbil", "turtle"],
    arrayTwo = ["hamster", "turtle", "gerbil"],
    doNotMatch = []; 

for(var i=0;i<arrayOne.length;i++){
   if(arrayTwo.indexOf(arrayOne[i])==-1){doNotMatch.push(arrayOne[i]);}
}

//doNotMatch is now ["dog","cat"]
