I have a little issue that I couldn't figure out. I have a slider and I want to change url when I click prev and next buttons. Here are my codes below but it doesn't work correctly. Every time I click the button, url appending instead of replacing.

var url = window.location.href;
url = url + "page/" + 1;  // this number is dynamic actually
window.location.href = url;

For instance it displays; stackoverflow/page and I clicked stackoverflow/page/1 and again stackoverflow/page/1/page/2

But I just want to replace it stackoverflow/page/1 to stackoverflow/page/2

How can I fix it? Thank you for your help.

window.location.href returns the entire url...

if you just want to add the "/page/1"

use

var url = window.location.origin;
url = url + "/page/" + 1;  // this number is dynamic actually
window.location.href = url;

though window.location.origin is undefined in windows 10

https://developer.mozilla/en-US/docs/Web/API/Window/location

you could just replace the /page/#number#

var url = window.location.href;
url = url .replace(new RegExp("/page/[0-9]"), "/page/2")
window.location.href = url;

All you want is a leading / in front of page to make a domain relative path

try

var url =  "/page/" + 1;

you can use regex to grab the page section and replace.

something like this:

let num = 2, url= "stackoverflow./page/1";
url = url.replace(/(page\/)([0-9]{1,})/, "$1"+num)
