The following functions will take a path to a file and return various portions of it.
getFileName[]
function getFilename(path) {
var pos = Math.max(path.lastIndexOf('/'), path.lastIndexOf('\\'));
return path.substr(pos + 1);
}
Results
- getFilename("/Applications/Utilities/Activity Monitor.app") == "Activity Monitor.app"
- getFilename("C:\\Program Files\\Pixoria\\Konfabulator\\README.rtf") == "README.rtf"
- getFilename("C:\\WINDOWS\\") == ""
(Not recommended - use filesystem.isDirectory() before calling getFilename)
getExtension[]
function getExtension(path) {
var pos = path.lastIndexOf('.');
return (pos < 0) ? "" : path.substr(pos + 1);
}
Results
- getExtension("/Applications/Utilities/Activity Monitor.app") == "app"
- getExtension("C:\\Program Files\\Pixoria\\Konfabulator\\README.rtf") == "rtf"
- getExtension("~/Desktop/foo") == ""
- getExtension("C:\\WINDOWS\\") == ""
(Not recommended - use filesystem.isDirectory() before calling getExtension)
getFilenameWithoutExtension[]
function getFilenameWithoutExtension(path) {
var pos1 = Math.max(path.lastIndexOf('/'), path.lastIndexOf('\\'));
var pos2 = path.lastIndexOf('.');
return (pos2 < pos1) ?
path.substr(pos1 + 1) : path.substr(pos1 + 1, pos2 - (pos1 + 1));
}
Results
- getFilenameWithoutExtension("/Applications/Utilities/Activity Monitor.app") == "Activity Monitor"
- getFilenameWithoutExtension("C:\\Program Files\\Pixoria\\Konfabulator\\README.rtf") == "README"
- getFilenameWithoutExtension("~/Desktop/foo") == "foo"
- getFilenameWithoutExtension("C:\\WINDOWS\\") == ""
(Not recommended - use filesystem.isDirectory() before calling getFilenameWithoutExtension)
getFolder[]
function getFolder(path) {
var pos = Math.max(path.lastIndexOf('/'), path.lastIndexOf('\\'));
return path.substr(0, pos + 1);
}
Results
- getFolder("/Applications/Utilities/Activity Monitor.app") == "/Applications/Utilities/"
- getFolder("C:\\Program Files\\Pixoria\\Konfabulator\\README.rtf") == "C:\\Program Files\\Pixoria\\Konfabulator\\"
- getFolder("~/Desktop/foo") == "~/Desktop/"
- getFolder("C:\\WINDOWS\\") == ""
(Not recommended - use filesystem.isDirectory() before calling getFolder)
