Javascript – How to extract filename from a file input control

To split the string ({filepath}/{filename}) and get the file name you could use something like this:

str.split(/(\\|\/)/g).pop()

“The pop method removes the last element from an array and returns that
value to the caller.”
Mozilla Developer Network

Example:

from: "/home/user/file.txt".split(/(\\|\/)/g).pop()

you get: "file.txt"
