Question

我有一个数组，我开始：

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"}}];

这个数组有5个元素。然后我从我的服务器获得5个以上的结果。我想将这个新数组附加到现有数组。

所以我从服务器收到了这个：

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"}}];

为了合并它们，我去了：

console.log(array1.push(server_response);

但我得到以下结果：

[{ “键”：{ “ID”：1， “一种”： “表”， “路径”：[ “表”，1]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294950 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：2 “一种”： “表”， “路径” ：[ “表”，2]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294953 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：3 “一种”： “表”， “路径” ：[ “表”，3]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294954 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：4 “一种”： “表”， “路径” ：[ “表”，4]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294954 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：5 “一种”： “表”， “路径” ：[ “表”，5]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294954 “CAT1”： “A1”， “许可”： “N”}}， [{ “键”：{ “ID”：6中， “种类”： “表” “路径”：[ “表”，6]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294954 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：7， “一种”： “表”， “路径” ：[ “表”，7]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294954 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：8中， “种类”： “表”， “路径” ：[ “表”，8]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294954 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：9 “一种”： “表”， “路径” ：[ “表”，9]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294955 “CAT1”： “A1”， “许可”： “N”}}，{ “键”：{ “ID”：10， “一种”： “表”， “路径” ：[ “表”，10]}， “数据”：{ “TXT”：“一些 TXT”， “修饰的”：1461294955 “CAT1”： “A1”， “许可”： “N”}}]

如您所见，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（基本上应该没有方括号）。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。如何合并这些数组？

Answer 1

我相信您正在寻找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

尝试使用concat方法......

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

Answer 3

我想将这个新数组附加到现有数组。

如果您不想创建新阵列，可以使用Array.prototype.push.apply。 Array.prototype.push.apply将使用array1的内容更新您的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);
