Javascript deep copy

Let's take a look at the defects of the shortest replication. I don't know how many people have done it? CopyCode The Code is as follows: var ooriginal = {
Memnum: 1, // number
Memstr: "I am a string", // string
Memobj :{
Test1: "old value" // We'll test
},
Memarr: [// Array
"A string", // string member of Array
{// Object member of Array
Test2: "try changing me" // We'll test
}
]
};

This is a complex object that contains objects and arrays. Let's take a look at the complexity of the famous inheritance function of prototype. It is hard to say that it is inheritance, and jquery does not.Copy codeCode: var extend = function (result, source ){
For (var key in source)
Result [Key] = source [Key];
Return result;
}

TestProgram:Copy codeThe Code is as follows: var ocopy = extend ({}, ooriginal); // light copy
Ocopy. memobj. test1 = "New Value"; // if a problem occurs, it is reflected to the original object.
Alert (ooriginal. memobj. test1); // The result copy is modified together with the original one.
Ocopy. memarr [1]. Test2 = "I am changed ";
Alert (ooriginal. memarr [1]. Test2 ); //
