本文實例講述了javascript數組克隆簡單實現方法。分享給大家供大家參考，具體如下：
<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>新建網頁 1</title></head><body><script language=javascript>var a = ['a','b','c','d','e','f'];var b = a.concat();b.push('test is ok!');alert(b.join(','));alert(a.join(','));</script></body></html>武林網小編補充
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!
希望本文所述對大家JavaScript程序設計有所幫助。
