本文实例讲述了javascript数组克隆简单实现方法。分享给大家供大家参考,具体如下:
编程之家小编补充
The JavaScript To clone the contents of a given array,all you need to do is call slice,providing 0 as the first argument:
var clone = myArray.slice(0);
The code above creates clone of the original array; keep in mind that if objects exist in your array,the references are kept; i.e. the code above does not do a "deep" clone of the array contents. To add clone as a native method to arrays,you'd do something like this:
Array.prototype.clone = function() { return this.slice(0); };
And there you have it! Don't iterate over arrays to clone them if all you need is a naive clone!
希望本文所述对大家JavaScript程序设计有所帮助。
