I've been using this script for several years. I change the file name of the images to 1.jpg, 2.jpg..etc. Is there a way I can change this script to use wildcards to read the files in a specific directory? Also, I change the variable - NUMBER_OF_IMAGES to reflect how many images are in the directory. I know this can be done in PHP, but I would like to see if it can be done with what I have so far.
Thanks for your help.
<script language="JavaScript"><!--
which_image_loaded = 0;
NUMBER_OF_IMAGES = 8;
ImageNames = new Array;
ImageNames.length = NUMBER_OF_IMAGES - 1;
for (counter = 0; counter < NUMBER_OF_IMAGES; counter++){
file_number = counter + 1;
filename = (file_number + ".jpg");
ImageNames[counter] = filename;
}
function changeImage(direction) {
which_image_loaded += direction;
if (which_image_loaded < 0)
which_image_loaded = NUMBER_OF_IMAGES - 1;
var jim = which_image_loaded;
if (which_image_loaded == NUMBER_OF_IMAGES)
which_image_loaded = 0;
document.jobimage.src = ImageNames[which_image_loaded];
}
//--></script>
