Regex that matches anything not ending in .json

Question

For a web app I\'m trying to come up with a javascript regex that matches anything not ending in .json. Sounds simple but I\'m finding it pretty damn hard.

Answer 1

Try /^(?!.*\.json$).*$/

/^(?!.*\.json$).*$/.test("foo.json")
false
/^(?!.*\.json$).*$/.test("foo")
true
/^(?!.*\.json$).*$/.test("foo.html")
true
