jQuery的深度复制对象数组属性值

Question

Take a look at this snippet:

$.extend( true, {}, { key: ["somevalue"] }, { key: ["anothervalue"] })

doing this I expect the produced object will contain a property called "key" which is an array and has 2 elements, eg

{ key: ["somevalue", "anothervalue"] }

Am I just giving the deep copy more than it can handle?

Answer 1

Nop !! The result will be a object containing key having value ["anothervalue"], you are basically overriding the "key" as you pass more objects in the arguments with key as "key"

Thanks
