    stripping text

    could someone help me with stripping text off the end of a string in JS? need to replace text at the end of a given string and then add it back again.

    cheers.

    Regular Expressions are pretty much the way to go, yes.
    Of course, that's just my opinion. I could be wrong.

    It depends on precisely what you're doing - it might be more efficient to use a simple indexOf() call...

    what i'm doing is this... on an event i am taking the .src of an image and suffixing that with "_over.gif" (a separate file), and then on another event, replacing "_over.gif" with ".gif", creating the rollover effect. i am doing this currently with regular expressions.

    Well, if you were doing this with a significant number of images in a loop you'd be better off with .indexOf() from an efficiency POV, but using a RegEx for a single string isn't going to make any perceptible difference...
