正则表达式匹配-Javascript

Question

I am trying to write a RegEx that will match this:

/Admin/doctemplate/edit/-537743660332489375

And the id number at the end can change. Also a separate RegEx to match like so:

/Admin/doctemplate/-537743660332489375/edit

I have tried:

/Admin/doctemplate/edit/[-0-9]+/

Answer 1

You need to escape the forward slashes. Then you can use the digit class \\d for the numbers ( [-0-9]+ would also match 0-4-6-58---458 , which I don't think you want).
1. \\/Admin\\/doctemplate\\/edit\\/-\\d+
2. \\/Admin\\/doctemplate\\/-\\d+\\/edit

I highly recommend regexr for messing with regex.

Answer 2

here is the regex for both cases:

/^\/Admin\/doctemplate\/(edit\/-?\d+|-?\d+\/edit)$/

with your two example:

/^\/Admin\/doctemplate\/(edit\/-?\d+|-?\d+\/edit)$/.test(yourString1) ->true
/^\/Admin\/doctemplate\/(edit\/-?\d+|-?\d+\/edit)$/.test(yourString2) ->true

if you want to use the test multiple times, better make it as a variable:

var re= new RegExp("^/Admin/doctemplate/(edit/-?\d+|-?\d+/edit)$")
re.test(...)
