本篇内容主要讲解"js怎么获取两个数组及数组对象中相同和不相同的值"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"js怎么获取两个数组及数组对象中相同和不相同的值"吧!

1、获取两个数组中相同的元素

var arr1 = [0,1,2,3,4,5];var arr2 = [0,4,6,1,3,9];function getArrEqual(arr1, arr2) { let newArr = []; for (let i = 0; i < arr2.length; i++) { for (let j = 0; j < arr1.length; j++) { if(arr1[j] === arr2[i]){ newArr.push(arr1[j]); } } } return newArr;}console.log(getArrEqual(arr1, arr2));//[0, 4, 1, 3]

2、获取两个数组中不相同的元素

var arr1 = [0,1,2,3,4,5];var arr2 = [0,4,6,1,3,9];function getArrDifference(arr1, arr2) { return arr1.concat(arr2).filter(function(v, i, arr) { return arr.indexOf(v) === arr.lastIndexOf(v); });}console.log(getArrDifference(arr1,arr2)); // [2, 5, 6, 9]

3、获取两个数组对象中相同的值

function getArrDifSameValue(arr1,arr2){ var result = []; for(var i = 0; i < arr2.length; i++){ var obj = arr2[i]; var id = obj.id; var isExist = false; for(var j = 0; j < arr1.length; j++){ var aj = arr1[j]; var n = aj.id; if(n == id){ isExist = true; break; } } if(isExist){ result.push(obj); } } return result;} var arr1 = [ {"id": "A"},{"id": "B"}];var arr2 = [ {"id": "A"}, {"id": "B"},{"id": "C"}];console.log(getArrDifSameValue(arr1,arr2));

4、获取两个数组对象中不相同的值

function getArrDifSameValue(arr1,arr2){ var result = []; for(var i = 0; i < arr2.length; i++){ var obj = arr2[i]; var id = obj.id; var isExist = false; for(var j = 0; j < arr1.length; j++){ var aj = arr1[j]; var n = aj.id; if(n == id){ isExist = true; break; } } if(!isExist){ result.push(obj); } } return result;} var arr1 = [ {"id": "A"},{"id": "B"}];var arr2 = [ {"id": "A"}, {"id": "B"},{"id": "C"}];console.log(getArrDifSameValue(arr1,arr2));// [{"id": "C"}]到此，相信大家对"js怎么获取两个数组及数组对象中相同和不相同的值"有了更深的了解，不妨来实际操作一番吧!这里是网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习!
