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。
