Remove Preceding Characters in RegExp Javascript

Question

I have a problem sanitizing dynamic URLs eg

 var uri = '/localhost:8080////app//user/login.json?foo=bar';
 var sanitizedUri = uri.replace(/\.json*/, '');

 // print ==> /localhost:8080////app//user/login?foo=bar

What I want here is when " .json " is present in the URL, I want to remove .json and succeeding characters (query params) and will only output the following:

/localhost:8080////app//user/login<br>

Note foo=bar is a dynamic value.

Answer 1

Try adding .

(The dot, the decimal point) matches any single character except line

to RegExp before * to

Matches the preceding item x 0 or more times.

following \\.json

 var uri = '/localhost:8080////app//user/login.json?foo=bar'; var sanitizedUri = uri.replace(/\\.json.*/, ''); console.log(sanitizedUri)
