javascript数组在创建时不为空 [英] javascript array is not empty on creation

问题描述

我目前正在使用重型javascript的网络应用程序。在一个

的函数中，使用var admin_types =

new Array（）;创建一个简单的数组。此数组不为空，长度为0但

包含一个名为clone的元素。和价值


function（）{var copy = {}; for（var i in this）{var value = this [i];

try {if（value！= null&& typeof（value）==" object"&&值！=

window&&！value.nodeType）{value.clone = Object.clone; copy [i] =

value.clone（）; } else {copy [i] = value; catch（e）{copy [i] =

value;返回副本; }


为什么要创建这个元素？奇怪的是我使用了很多

的数组，这是唯一拥有该元素的数据。


i在firefox 1.0中尝试过这个，即5.5和mozilla 1.7.1和元素

在所有这些元素的数组中...

任何帮助将不胜感激

Hi,

im currently working on a web app which uses heavy javascript. in one
of the functions, a simple array is created using "var admin_types =
new Array();". This array is not empty, it has a length of 0 but
contains one element with the name "clone" and the value

function () { var copy = {}; for (var i in this) { var value = this[i];
try { if (value != null && typeof (value) == "object" && value !=
window && !value.nodeType) { value.clone = Object.clone; copy[i] =
value.clone(); } else { copy[i] = value; } } catch (e) { copy[i] =
value; } } return copy; }

why does this element get created?? The weird thing is that i use a lot
of arrays and this is the only one that has that element.

i tried this in firefox 1.0, ie 5.5 and mozilla 1.7.1 and the element
is in the array for all of them...
any help would be appreciated
Rusty

推荐答案

我刚刚发现网络应用程序中的所有数组都有

" clone"元件。当我在创建数组的头部创建一个带有javascript

函数的简单html页面时，它不包含

" clone"元素......

i just discovered that all of the arrays in the web app have the
"clone" element. When i created a simple html page with a javascript
function in the head that creates an array, it does not contain a
"clone" element...

它不是数组的元素，它是Array对象的一种方法。

It''s not an element of the array, it''s a method of the Array object.

如果它是一个方法，为什么你可以使用admin_types [''clone'']来访问它？

if its a method, why can u access it using admin_types[''clone''] ??
