合并这2个阵列

Question

我有一个数组我在开始时：

var array1 = [{"key":{"id":1,"kind":"Table","path":["Table",1]},"data":{"txt":"some txt","modified":1461294950,"cat1":"a1","permission":"n"}}, 
{"key":{"id":2,"kind":"Table","path":["Table",2]},"data":{"txt":"some txt","modified":1461294953,"cat1":"a1","permission":"n"}}, 
{"key":{"id":3,"kind":"Table","path":["Table",3]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":4,"kind":"Table","path":["Table",4]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":5,"kind":"Table","path":["Table",5]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}]; 

该阵列具有5个元素。然后我从我的服务器获得5个更多的结果。我想将这个新数组添加到现有的。

所以我接受这个从我的服务器：

var server_response = [{"key":{"id":6,"kind":"Table","path":["Table",6]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":7,"kind":"Table","path":["Table",7]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":8,"kind":"Table","path":["Table",8]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":9,"kind":"Table","path":["Table",9]},"data":{"txt":"some txt","modified":1461294955,"cat1":"a1","permission":"n"}}, 
{"key":{"id":10,"kind":"Table","path":["Table",10]},"data":{"txt":"some txt","modified":1461294955,"cat1":"a1","permission":"n"}}]; 

因此合并它们，我去：

console.log(array1.push(server_response); 

但我得到以下结果：

[{“键“：{”id“：1，”kind“：”Table“，”path“：[”Table“，1]}，”data“：{”txt“：”some txt“，”modified“：1461294950 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：2， “kind”：“Table”，“path”：[“Table”，2]}，“data”：{“txt”：“some txt”，“modified”：1461294953，“cat1” “许可”： “N”}}，{ “键”：{ “ID”：3 “一种”： “表”， “路径”：[ “表”，3]}， “数据”：{“TXT “：”some txt“，”modified“：1461294954，”cat1“：”a1“，”permission“：”n“}}，{”key“：{”id“：4，”kind“：”Table “，”path“：[”Table“，4]}，”data“：{”txt“：”some txt“，”modified“：1461294954，”cat1“：”a1“，”permission“：”n “}”，{“key”：{“id”：5，“kind”：“Table”，“path”：[“Table”，5]}，“data”：{“txt” “，”修改“：1461294954，”cat1“：”a1“，”权限“：”n“}}，[{”key“：{”id“：6，”kind“：”Table“，”path “：[”Table“，6]}，”data“：{”txt“：”some txt“，”modified“：1461294954，”cat1“：”a1“，”permission“：”n“}} {“key”：{“id”：7，“kind”：“Table”，“path”：[“Table”，7]}，“data”：{“txt”：“some txt”，“modified “：1461294954，” CAT1 “：” A1" ， “许可”： “N”}}，{ “关键”：{ “ID”：8，“种“：”Table“，”path“：[”Table“，8]}，”data“：{”txt“：”some txt“，”modified“：1461294954，”cat1“：”a1“ “：” N “}}，{” 键 “：{” ID “：9”，一种 “：” 表”， “路径”：[ “表”，9]}， “数据”：{ “TXT”： “some txt”，“modified”：1461294955，“cat1”：“a1”，“permission”：“n”}}，{“key”：{“id”：10，“kind”：“Table” “path”：[“Table”，10]}，“data”：{“txt”：“some txt”，“modified”：1461294955，“cat1”：“a1”，“permission”：“n”} }]]

正如你所看到的，它将第二个数组作为实际数组添加到第一个数组。我只想添加服务器响应的内容（基本上不应该有方括号）。我知道我可以使用正则表达式来做到这一点，但这似乎不是一个好的解决方案。我怎样才能合并这些数组？

Answer 1

我相信你正在寻找concat

var array1 = [{"key":{"id":1,"kind":"Table","path":["Table",1]},"data":{"txt":"some txt","modified":1461294950,"cat1":"a1","permission":"n"}}, 
{"key":{"id":2,"kind":"Table","path":["Table",2]},"data":{"txt":"some txt","modified":1461294953,"cat1":"a1","permission":"n"}}, 
{"key":{"id":3,"kind":"Table","path":["Table",3]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":4,"kind":"Table","path":["Table",4]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":5,"kind":"Table","path":["Table",5]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}]; 
var server_response = [{"key":{"id":6,"kind":"Table","path":["Table",6]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":7,"kind":"Table","path":["Table",7]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":8,"kind":"Table","path":["Table",8]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
{"key":{"id":9,"kind":"Table","path":["Table",9]},"data":{"txt":"some txt","modified":1461294955,"cat1":"a1","permission":"n"}}, 
{"key":{"id":10,"kind":"Table","path":["Table",10]},"data":{"txt":"some txt","modified":1461294955,"cat1":"a1","permission":"n"}}]; 
console.log(array1.concat(server_response)); 

Answer 2

我想追加这个新的数组到现有的。

如果您不想创建新阵列，则可以使用Array.prototype.push.apply。 Array.prototype.push.apply将更新您的array1，其内容为server_push。

见下文：

var array1 = [{"key":{"id":1,"kind":"Table","path":["Table",1]},"data":{"txt":"some txt","modified":1461294950,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":2,"kind":"Table","path":["Table",2]},"data":{"txt":"some txt","modified":1461294953,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":3,"kind":"Table","path":["Table",3]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":4,"kind":"Table","path":["Table",4]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":5,"kind":"Table","path":["Table",5]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}]; 
 

 
var server_response = [{"key":{"id":6,"kind":"Table","path":["Table",6]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":7,"kind":"Table","path":["Table",7]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":8,"kind":"Table","path":["Table",8]},"data":{"txt":"some txt","modified":1461294954,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":9,"kind":"Table","path":["Table",9]},"data":{"txt":"some txt","modified":1461294955,"cat1":"a1","permission":"n"}}, 
 
{"key":{"id":10,"kind":"Table","path":["Table",10]},"data":{"txt":"some txt","modified":1461294955,"cat1":"a1","permission":"n"}}]; 
 

 
Array.prototype.push.apply(array1, server_response); 
 

 
document.body.textContent = JSON.stringify(array1);

Answer 3

尝试concat方法...

MergedArray=Array1.concat(Array2,Array3,Array4);
