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

You can always just get the file extension and then compare it.

Regex to find file extension

/\.[^.]*$/

get the file extension with

var extension = /\.[^.]*$/.exec("something.json");

if(extension[0] === ".json"){
    //do something
}
