Remove text from object name or string.

[dgolberg]

How does one go about removing certain parts of a word, name, or string?  For example; I have a document where there are layers such as "trim - highlight" or "trim - color" etc.  These are already in a group called trim, so having the prefix "trim - " is kind of redundant.

I'm basically loading these layers into an array based on their group, then saving them out based on their layer name.  This isn't really a problem for new projects, but some of our older ones still use the old naming with the redundancy; so I'd like to build something into our saving script to automatically remove this redundancy before saving the layer.  Any help is appreciated.

You can remove the trim - for the active layer....

activeDocument.activeLayer.name =  activeDocument.activeLayer.name.replace(/trim -/i,'');

That worked great Paul! Thanks a ton!

There is one other thing, though, that I can see being handy in the near future.  Is there way to get it to check if that exists before changing it?  For example, having it check a string to see if it ends in .jpg or not, and if it doesn't, adding that in.

Something like this....

var str = "FilesName";
if(!str.match(/.jpg$/)) str = str + ".jpg";
alert(str);

Awesome! Thanks again Paul!  One last thing (simple question), what does the $ represent in that last script?  Does it tell it to check only the end of the string?

Sorry, I'm still more of a script hacker than writer at this point... so trying to learn what all the various symbols do.

You've got it in one.

if(!str.match(/^.jpg/)) str = str + ".jpg";

This checks if .jpg is at the front of the string.

This site is a good starting point for regular expressions...

Thanks a ton!  Adding that site to my (currently short) list of scripting info sites.
