How is this Javascript extended to replace the domain name etc?

Hello,

I'm using the Javascript thumbnail viewer called Highslide (http://highslide.com/). One of the commands that are available allow an image filename to be added as a image caption.

For example:
hs.captionEval = 'this.content.src.replace(\'.jpg\', \'\')';

...will remove the '.jpg' from the filename.

Please can some tell me how i can extend this so that the current caption can be changed from:
http://www.globexposure.net/includes/travel_pics/163/Toby Texas%20Chainsaw%20Massacre.jpg
to
Toby Texas Chainsaw Massacre

Please note, however, that the '163' element of the current name is an id variable, and will therefore change between images.

Many thanks for your help

This might help:

hs.captionEval = this.content.src.replace(\'.jpg\', \'\');
//add this line after:
hs.captionEval= hs.captionEval.substr(myString.lastIndexOf('/')+1));

try:

var str="http://www.globexposure.net/includes/travel_pics/163/Toby Texas%20Chainsaw%20Massacre.jpg";
var result = str.replace( /.*\/([^\/]+)\.jpg$/i,"$1")
alert( result );

Blu - your code makes the whole caption area under the images, disappear!

Hielo - sorry perhaps i wasn't clear, each image on my site (there will be hundreds) needs to have its filename set to be the caption. Therefore, it is not possible to hardcode the var 'str'.
Is there a way var str could be set dynamically?

hielo

the hard-coded value was just an example. What you really need is:

hs.captionEval = 'this.content.src.replace( /.*\/([^\/]+)\.jpg$/i,"$1")';

Hi Hielo,

It looks very complex, but i'm afraid that it doesn't appear to do anything. I can't begin to understand what it does but hopefully you can see what's wrong.

Thanks again but please keep trying.

Yeah right. Not in the dark!

Try this:
myString = this.content.src.replace(\'.jpg\', \'\');
//add this line after:
hs.captionEval= hs.captionEval.substr(myString.lastIndexOf('/')+1));

Hi Blu - your code seems to hide both the caption and controlbar

You can see the effect here www.globexposure.net/index_blu.php

as opposed to the normal look www.globexposure.net/index.php
