原生JavaScript实现合并多个数组示例

1、原生的JavaScript实现

var array1 = ["a", "b"];

var array2 = ["c", "d"];

<span class="keyword" style="font-weight:bold">var</span> <span class="keyword" style="font-weight:bold">array</span>= [<span class="string" style="color:rgb(221,17,68)">"a"</span>, <span class="string" style="color:rgb(221,17,68)">"b"</span>, <span class="string" style="color:rgb(221,17,68)">"c"</span>, <span class="string" style="color:rgb(221,17,68)">"d"</span>];

可以使用

arr1.concat(arr2);

$.merge(array1,array2);

console.log($.unique(array1));
