使用javascript确定文件夹中的文件数 [英] Determining number of files in folder using javascript
问题描述
你好,
我想确定
文件夹中的图像文件数量,以便我可以相应地创建一个动态表格。为此我需要一种方法来识别文件夹中的文件数量。有没有
我可以估算这个,这样我就可以确定一个
数组的大小来创建我的桌子
问候

客户端JS无法做到这一点。它在任何服务器端语言中都是微不足道的。
虽然。
有什么办法我可以估计这个以便我可以确定
创建表格的数组大小
嗯?没有任何意义。

在Javascript中,你永远不必在使用
之前对数组进行维度。你可以这样做:
var imgs =抓取图像的一些代码
var imgArray = []; /创建一个空数组
for(var t = 0; t = imgs [t]; t ++)
imgArray.push(t);
并且您的阵列将被填充

吧。你可以这样做:

for(var t = 0; t = imgs [t]; t ++)
imgArray.push(t);
你的数组将填充
嘿,谢谢你。我正在分配新元素:
imgArray [imgArray.length] = t;
我知道它效率低下,从未想过我想是使用推送。我现在感觉很闷气。
非常感谢!

hello,
I am looking to determine the number of image files in a
folder so that I could create a dynamic table accordingly. For this i
need a method to identify the number of files in a folder. Is there
any way i could estimate this so that i could determine the size of an
array to create my tables
regards
Prashant

need a method to identify the number of files in a folder.Client-side JS can''t do that. It is trivial in any server side language
though.
Is there any way i could estimate this so that i could determine
the size of an array to create my tablesHuh? Nothing in that makes any sense.

PrashantIn Javascript, you never have to dimension an array before you use
it. You can just do something like this:
var imgs = some code that grabs the images
var imgArray = []; / create an empty array
for (var t=0; t=imgs[t]; t++)
imgArray.push(t);
and your array will be populated

imgArray[imgArray.length] = t;
I knew it was inefficient, just never thought to use push, I suppose. I
feel sully now.
Thanks a ton!
