Question

I have a file location in a variable and all I need to do is get the value from the last / onwards.

For example the contents of my variable (named myfile) would look like /home/tony/files/test.pdf or /tmp/admin.doc. I just want to go to the end of the variable and go backwards until I get to a / and then take the value from that point onwards.

Any ideas?

You can accomplish this using String.substring() and String.lastIndexOf():

var index = myfile.lastIndexOf('/');
if(index != -1)
{
    var newStr = myfile.substring(index + 1);
}

Another method of doing this would be to use regular expressions:

var newStr = myfile.replace(/^.*\/(?=[^\/]*$)/, '');
