String.endsWith(/[string]/[1-999]/)

Question

I'm trying to parse the end of a url and redirect depending on it's ending.

For example, if I'm going to www.something.com/foo/1/ I want to redirect to www.something.com/foo/1/bar . The 1 in this case can be any positive integer.

What I've been trying with but can't get to work is:

if (window.location.href.endsWith('/foo/\\d/')) { fetch stuff and redirect } else { do something else }

Which doesn't work, I'm guessing endsWith can't parse regex.

Thanks in advance,

Peter

Answer 1

In your code endsWith('/foo/\\d/') check the string is ending with that particular string argument and won't work as a regex.

For checking using regex use RegExp#test method with regex /foo\\/\\d{1,3}\\/$/ .

if(/foo\/\d{1,3}\/$/.test(window.location.href)) 

Answer 2

You can regex match for the end of string instead,

/.*foo\d/$/

My regex might be wrong, but you can use the $ to denote end of string and just do a regular regex.test
