合并 2 个对象数组

让我们看一个例子。

var arr1 = new Array({name: "lang", value: "English"},
                     {name: "age", value: "18"});

var arr2 = new Array({name : "childs", value: '5'},
                     {name: "lang", value: "German"});

我需要合并这两个对象数组并创建以下数组：

var arr3 = new Array({name: "lang", value: "German"},
                     {name: "age", value: "18"},
                     {name : "childs", value: '5'});

有没有 JavaScript 或 jQuery 函数可以做到这一点？

$.extend不适合我。它返回

var arr4 = new Array({name : "childs", value: '5'},
                     {name: "lang", value: "German"});

如果你想在 JavaScript 中合并 2 个对象数组。你可以使用这一行技巧

Array.prototype.push.apply(arr1,arr2);

例如

var arr1 = [{name: "lang", value: "English"},{name: "age", value: "18"}];
var arr2 = [{name : "childs", value: '5'}, {name: "lang", value: "German"}];

Array.prototype.push.apply(arr1,arr2); 

console.log(arr1);  // final merged result will be in arr1

Output:

[{"name":"lang","value":"English"},
{"name":"age","value":"18"},
{"name":"childs","value":"5"},
{"name":"lang","value":"German"}]
