javascript match and add string in dynamic Url

Question

I have a dynamic URL, which i want to append some string at last

 'http://staging.mydomain.name.com/test/7bb12c5f7b2f4f008261bea2d3f5abd2/200x200.png'

want to append "preview" before size (200x200.png which is also dynamic), something like below

'http://staging.mydomain.name.com/test/7bb12c5f7b2f4f008261bea2d3f5abd2/preview/200x200.png'

Thanks

Just use a simple regular expression like:

'http://.../200x200.png'.replace(/[^\/]+$/, 'preview/$&')

You can do like str.replace(/(/\d+x\d+.)/,'/preview$1')
