Find base name in URL in Javascript

Question

I want to extract the base name from a image URL in Javascript. Would somebody care to give me a a hand on the Regex?

The rule would be:

• return ever

Answer 1

I wouldn't actually use a regex in this case, but simply lastIndexOf and substring. Something like

function findBaseName(url) {
    var fileName = url.substring(url.lastIndexOf('/') + 1);
    var dot = fileName.lastIndexOf('.');
    return dot == -1 ? fileName : fileName.substring(0, dot);
}
