合併這2個陣列

Question

我有一個數組我在開始時：

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"}}]; 

該陣列具有5個元素。然後我從我的服務器獲得5個更多的結果。我想將這個新數組添加到現有的。

所以我接受這個從我的服務器：

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"}}]; 

因此合併它們，我去：

console.log(array1.push(server_response); 

但我得到以下結果：

[{「鍵「：{」id「：1，」kind「：」Table「，」path「：[」Table「，1]}，」data「：{」txt「：」some txt「，」modified「：1461294950 「CAT1」： 「A1」， 「許可」： 「N」}}，{ 「鍵」：{ 「ID」：2， 「kind」：「Table」，「path」：[「Table」，2]}，「data」：{「txt」：「some txt」，「modified」：1461294953，「cat1」 「許可」： 「N」}}，{ 「鍵」：{ 「ID」：3 「一種」： 「表」， 「路徑」：[ 「表」，3]}， 「數據」：{「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「，」權限「：」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" ， 「許可」： 「N」}}，{ 「關鍵」：{ 「ID」：8，「種「：」Table「，」path「：[」Table「，8]}，」data「：{」txt「：」some txt「，」modified「：1461294954，」cat1「：」a1「 「：」 N 「}}，{」 鍵 「：{」 ID 「：9」，一種 「：」 表」， 「路徑」：[ 「表」，9]}， 「數據」：{ 「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，它將第二個數組作爲實際數組添加到第一個數組。我只想添加服務器響應的內容（基本上不應該有方括號）。我知道我可以使用正則表達式來做到這一點，但這似乎不是一個好的解決方案。我怎樣才能合併這些數組？

Answer 1

我相信你正在尋找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

我想追加這個新的數組到現有的。

如果您不想創建新陣列，則可以使用Array.prototype.push.apply。 Array.prototype.push.apply將更新您的array1，其內容爲server_push。

見下文：

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

嘗試concat方法...

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