Hello i need to match filnames with extensions.
Problem is that paths could be both unix and windows, so seperated by / or \ also unix allows . in filenames, so t.est.txt also should be matched.
My code :
var regex = new RegExp('[\\/]?([/\w+.]+/\w+)/\s*$');
var value = this.attachment.fileInput.dom.value;
console.log(value.match(regex));
console.log(regex.exec(value));
this regex works fine in rubular. But for some reason ie, chrome and firefox does not match any string and returns null.
You could just grab whatever's at the end following the last \ or /, such as:
var file = str.match(/[^\\/]+$/)[0];
(Remember files don't always need extensions)
Though if you really want to force extension matching:
var file = str.match(/[^\\/]+\.[^\\/]+$/)[0];
Try the following syntax:
var filename = (value.match(/[^\\/]+\.[^\\/]+$/) || []).pop();
It should work fine for the following examples:
"path/to/file.ext" --> "file.ext"
"path\\to\\file.ext" --> "file.ext"
"path/to/file.ext.txt" --> "file.ext.txt"
"path/to/file" --> ""
Credits go to RegeBuddy's library for this snippet:
if (/[^\\\/:*?"<>|\r\n]+$/im.test(js)) {
// Successful match
} else {
// Match attempt failed
}
