javascript - 将数组插入数组的数组中 Javascript

Question

我尝试过拼接、连接、应用、调用等。

我想做的就是采用这样的数组:

[["alksjdflskdj","2","1.33","1.30","", "5","1","1","1","1","1","0","","Other notes"],
 ["test","1","","","","1","0","1","0","0","0","",""],
 ["test3","","","","","","0","0","0","0","0","",""],
 ["","","","","","","0","0","0","0","0","",""],
 ["","","","","","","0","0","0","0","0","",""]]

并在上面的数组中添加类似的内容:

["2018-03-06 04:14:59", "T", "", "", "0"]

最终结果如下所示:

[["alksjdflskdj","2","1.33","1.30","", "5","1","1","1","1","1","0","","Other notes"],
 ["test","1","","","","1","0","1","0","0","0","",""],
 ["test3","","","","","","0","0","0","0","0","",""],
 ["","","","","","","0","0","0","0","0","",""],
 ["","","","","","","0","0","0","0","0","",""],
 ["2018-03-06 04:14:59", "T", "", "", "0"]]

提前致谢。这让我很困惑。

Answer 1

您可以使用push()正如其他人已经提到的，为了将元素添加到现有数组:

arr1.push(ele); // arr1 now has ele at last index

您可以使用concat() ，它不会改变原始数组并返回一个全新的数组:

var arr2 = arr1.concat(ele) // arr1 remains the same and arr2 has arr1 with ele at las index

这取决于您的需求。
