[Javascript] Re: need script - slideshow with captions

Tue Mar 4 07:33:02 CST 2003

Hi 

Sorry to cut everyone short but you all trying to complicate your life with
2 array or trying to store data with this kind of process 
ok everyone thought of the array what is a good thing but you don't need a
seconde one for the caption because if you want to add a alt text to your
image or a link to an other page you will need to create new array and after
a will your code will be completely unmaintainable, What you need is to
store an object in your array 

I built this small examples with all you need this work only on IE but the
logic should drive you in better direction

All you need to do is ad another array of caption contents after or before 
the img arrays the same way:

NewCapt = new Array (
"this and that",
"caption contents",
"capiton3",

...until the last img caption and u're done
)

And at this line:

    document.slideshow.src = NewImg[ImgNum];

ad something like:

    caption.innerText = NewCapt[ImgNum];

and inside the HTML before this line:

   <img src="photos/beaders001.jpg" name="slideshow">

add the (in style) formated DIV:

   <DIV ID="caption">The Defalt img caption text</DIV>

And ure done.
Cheers!
