There are multiple ways we can retrieve fragmented url values

• use window.location.hash property:

window.location.hash property returns the fragmented value

if the page url is abc.com/about#contact

console.log(window.location.hash); //returns  #contact value

if url contains a string url, use the substring() method with the given index value.

var strUrl = "www.abc.com/about#contact";
var hash = strUrl.substring(strUrl.indexOf("#") + 1);
console.log(hash); // returns contact

var url = new URL("https://abc.com/about#contact");
console.log(url.hash); // returns #contact
