[英]Deep Copying an array using JQuery cannot copy array of Objects
Following is my use case I have objects a
, b
which has the following structure 以下是我的用例,我有对象
a
, b
,其结构如下
a={arr1:[obj1={x1:1,x2:2}, obj2={x1:4,x2:4}] , arr2:[obj1={x3:55,x4:66},obj2=
{x3:77,x4:88}]}
b={arr1:[obj1={x1:1,x2:2}, obj2={x1:4,x2:4},obj3={x1:44,x2:46}] , arr2:[obj1=
{x3:55,x4:66},obj2={x3:77,x4:88},obj1={x3:34,x4:45}]}
I want to copy the contents of a
to b
我要复制的内容,
a
以b
I tried using b=$.extend(true,b,a)
我尝试使用
b=$.extend(true,b,a)
but the contents of a
are not copied in b
. 但内容
a
都不能复制b
。 Object b
remains unchanged. 对象
b
保持不变。 The JSON format output of b
is as follows. b
的JSON格式输出如下。
{"arr1":[{"x1":1,"x2":2},{"x1":4,"x2":4},{"x1":44,"x2":46}],"arr2":[{"x3":55,"x4":66},{"x3":77,"x4":88},{"x3":34,"x4":45}]}
So what is the way to copy array contents. 那么复制数组内容的方法是什么。
This way you can join a Object Array into another. 这样,您可以将一个对象数组连接到另一个数组中。
I think this is pretty straight forward. 我认为这很简单。 Questions?
有问题吗? Ask me in the comments :)
在评论中问我:)
array1 = [{x:10, y:15}, {x:17, y:15}, {x:17, y:13}]; array2 = [{x:20, y:29}, {x:21, y:25}, {x:27, y:22}]; for(i=0; array1.length>i; i++){ array2.push(array1[i]); } console.log(array2);
