Implement a function clone to replicate values for 5 major data types in JavaScript, including number, String, Object, Array, Boolean.1 /** Object Cloning2 * Supports basic data types and objects3 * Recursive method*/ 4 functionClone (obj) {5

This article mainly introduces how to clone objects in javascript. If you need a friend, you can refer to the reference relationship between objects under development and interrupt them, but only the next copy is everywhere, it is inevitable to

Reprint: https://www.cnblogs.com/zouhao/p/7278117.htmlA: In JavaScript, if the cloned object is a basic type, we can assign it directly:1 var sStr = "Kingwell"; 2 var cStr = sstr;3 alert (cStr);//output KINGWELL4 SSTR = "ABC"; 5 alert

Clone is to copy the original thing as it is, and the new copy has nothing to do with the previous thing.A: In JavaScript, if the cloned object is a basic type, we can assign it directly:var sStr = "Kingwell"; var cStr = sStr; alert (CSTR); //

In-depth understanding of Object Clone and javascriptclone in JavaScript JavaScript does not directly provide the Object Clone method. Therefore, when object B is changed in the following code, object a is changed. A = {k1: 1, k2: 2, k3: 3 }; B =; B.

var srcobj = {A:1,B: {B1: ["Hello", "HI"],B2: "JavaScript"}};Console.log (Srcobj);var clone1 = Cloneobject (srcobj);function Cloneobject (SRC) {var clone = {};For (var item in SRC) {if (typeof (Src[item]) = = = ' object ') {if (Src[item] instanceof

I. In Javascript, if the cloned object is of the basic type, we can assign a value directly: 1 var sStr = "kingwell"; 2 var cStr = sStr; 3 alert (cStr); // output kingwell4 sStr = "abc"; 5 alert (cStr ); // output kingwell; When a value is assigned

JavaScript does not directly provide a method for object replication (the object clone). So when you change object B in the following code, you change object A. A = {k1:1, k2:2, k3:3}; b = A; B.K2 = 4; If you just want to change B and keep a

Development, interrupt the reference relationship between objects, just want the next copy of the situation everywhere, clone an object is inevitable. In JavaScript, the simple way is to use the JSON function, stringify the object into a string,

As javascript arrays are widely used and more friends are using them, students have compiled some js data learning materials for everyone. After reading them, they should have an understanding of arrays. In JavaScript, you can use new Array to
