1Yes because you added it on domcontent loaded. changing the search property of window.location will cause it to reload – Nicolas I Mar 31 '21 at 10:15

2I'm pretty sure setting values of `window.location` will cause the page to reload. You'll need an if-statement to prevent this – evolutionxbox Mar 31 '21 at 10:16
