大家好

我很抱歉，如果这对你们中的一些人来说很简单，但我有
很少有javascript的经验，我无法解决这个问题，

下面的代码是我在网上发现的一个很好的代码片段来旋转一组图像。它工作得很好。

由于你没有发布客户端代码，但是你发布了服务器端代码，所以很难说。

。 br />
但是，我想在HREF中放置一个值，指向当前正在显示的图像的更大版本

示例

显示的图像可能是缩略图tn_image1.jpg
我希望HREF指向图像image1.jpg（图像将始终与缩略图相同但没有tn_前缀）

任何帮助都会感激不尽。

只发布发送到浏览器的HTML。但下面的大部分代码

都是垃圾。

< A HREF=我如何导出这个>

Hi All

My apologies if this appears to be simple to some of you but I have
very little experience of javascript and I cannot work this one out,

The code below is a nice piece of code I found on the web to rotate a
set of images. It works very well.
It''s hard to tell since you didn''t post just the client side code but
you posted the server side code as well.
However, I would like to place a value in the HREF which points to a
larger version of the image currently being displayed

Example

The image being displayed may be a thumbnail tn_image1.jpg
I would like the HREF point to the image image1.jpg (the images will
always be the same name as the thumbnails but without the tn_ prefix).

Any help would be gratefully received
Post just the HTML that is sent to the browser. But most of the code
below is trash.

你用代码来推导它，如果你知道如何给你带来怎样的话会更容易发布了实际代码发送到浏览器而不是服务器

边码。甚至更好 - 一个示例页面的URL。

但是，它必须在slideit（）函数中完成。

总而言之，它看起来像是一个糟糕的幻灯片放映方式。

You Derive it with code, and it would be a lot easier to tell you how if
you posted the actual code going to the browser instead of the server
side code as well. And even better - a URL to a sample page.

But, it would have to be done in the slideit() function.

All in all, it looks like a crappy way to do a slide show.

您好Randy

感谢您的投入。

发布的代码是完整的实际工作的asp页面。我b $ b可以接受你的观点，这可能是一种糟糕的做事方式，但是我只是试图找出答案 - 作为一个相对比较好的人b $ b一点点javascript体验 - 如何动态地得出

HREF值的名称。

我一直在玩它但却无法获得该死的

工作的东西，所以我想我会问那些知道即javascript

组的民众喜欢你自己。

我设法找到了很多幻灯片的例子，其中实际上是b
，但我喜欢这个例子的原因是因为它是动态的。

更改外部文本的内容文件，你有一套新的

的幻灯片放映图像。不需要在物理上改变消息来源。

此外，我正在从例子中学习什么是坏事和丑陋

Hi Randy

Thanks for your input.
The code posted is the complete asp page which does actually work. I
can accept your point that it may be a crappy way to do things but I
was merely attempting to find out - as someone who has relatively
little javascript experience - how to dynamically derive the name of
the HREF value.

I have been playing around with it but just could not get the damn
thing to work so I thought I would ask those who know ie the javascript
group folk like yourself.

I have managed to find quite a few examples of slideshows that actually
work but the reason I liked this example was because it is dynamic.
Change the contents of the external text file and you have a fresh set
of images for the slide show. No need to physically change the source.

In addition, I am learning what is good bad and ugly from the examples

发布的代码是确实有效的完整asp页面。我可以接受你的观点，这可能是一种糟糕的做事方式，但我只是试图找出 - 作为一个有相对较少的javascript经验的人 - 如何动态地推导出来
HREF值的名称。

将示例URL发布到该ASP代码生成的页面。这使得编写

客户端代码变得更加简单。

我一直在玩它但是却无法得到该死的
工作所以我想我会问那些知道即javascript
群体的人，就像你自己一样。

< a id =" myLink" href =" noScripting.html">

然后在你的函数slideit（）中找到这一行：

document.images .slide.src = eval（" image" + step +" .src"）;

将它更改为我给你的行可能不会起作用它只是一个图像名称 - 一个字符串。

但是，为了改变href，你可以这样做：

document.getElementById（''myLink''）。href = newHREF;

其中newHREF是一个包含大图像href的变量。如何从你的脚本的其他部分获得这些内容取决于 -

直接 - 在你的ASP页面输出的代码上。这就是为什么我要求

来获取示例网址。

你告诉我你的ASP输出是什么，我可以告诉你更好的

脚本，它会做你想要的，更容易。

我设法找到了很多实际工作的幻灯片的例子，但我喜欢这个例子的原因是因为它是动态的。
更改外部文本文件的内容，你有一套新的幻灯片放映图像。不需要实际更改源代码。

can accept your point that it may be a crappy way to do things but I

the HREF value.
Post a sample URL to a page generated by that ASP code. It makes writing
client side code a lot simpler.
I have been playing around with it but just could not get the damn
thing to work so I thought I would ask those who know ie the javascript
group folk like yourself.
<a id="myLink" href="noScripting.html">

And then in your function slideit(), find this line:

document.images.slide.src=eval("image" + step + ".src");

Changing it to the line I gave you probably isn''t going to work if its
just an image name - a string.

But, to change the href you do something like this:

document.getElementById(''myLink'').href = newHREF;

Where newHREF is a variable that contains the href to the big image. How
you would go about getting that from the rest of your script depends -
directly - on the code your ASP page is outputting. That is why I asked
for a sample URL.

You show me what your ASP is outputting and I can show you a better
script and it will do what you want, a lot easier.
I have managed to find quite a few examples of slideshows that actually
work but the reason I liked this example was because it is dynamic.
Change the contents of the external text file and you have a fresh set

3年前，我用朋友为PHP写了一个，你甚至没有给
必须给它一个文本文件。它读取目录并获得文件名

本身。所有你需要做的就是放入缩略图和大图像，它剩下的就是
。

所以，将URL发布到使用的示例页面你的剧本。

I wrote one in PHP for a friend about 3 years ago that you didn''t even
have to give it a text file. It read the directory and got the filenames
itself. All you had to do was drop in the thumbnail and big image, it
did the rest.

So, post a URL to a sample page that uses your script.
