This article mainly explains "how to copy recursively in JavaScript". The content in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how to copy recursively in JavaScript.

1. To copy recursively.

/ / define a slightly more complex object

Var obj = {

Name: [{

Name: 'lisi'

}, {

Name: 'zhang'

Age: [{

Name: 'liu'

}]

}]

Age: '90'

}

Function deepClone (obj) {

/ / define a variable to store the result

Var result

/ / determine the type of transmission

If (obj = null | | typeof obj! = = 'object') return obj

/ / processing date object

If (obj instanceof Date) {

Result = new Date ()

Result.setTime (obj.getTime ())

Return result

}

/ / processing array

If (obj instanceof Array) {

Result = []

For (var I = 0; I < obj.length; iTunes +) {

Result [I] = arguments.call (obj [I])

}

Return result

}

/ / processing objects

If (obj instanceof Object) {

Result = {}

For (var key in obj) {

If (obj.hasOwnProperty (key) result [key] = arguments.callee (obj [key])

}

Return result

}

}

two。 Use the new API available in ES5

Var obj = {

Name: [{

Name: 'lisi'

}, {

Name: 'zhang'

Age: [{

Name: 'liu'

}]

}]

Age: '90'

}

Function deepClone (obj) {

/ / define a variable to store the result

Var result

/ / determine the type of transmission

If (obj = null | | typeof obj! = = 'object') return obj

/ / processing date object

If (obj instanceof Date) {

Result = new Date ()

Result.setTime (obj.getTime ())

Return result

}

If (typeof obj = = 'object') {

Result = JSON.parse (JSON.stringify (obj))

Return result

}

}
