Appending current URL parameters onto anchor link

At a page like

https://www.example.com/?firstname=Steven&lastname=Smith&email=steve%40gmail.com&phone=0404555555

I have a button (anchor link) #ptsBlock_553944 .ptsCell:nth-of-type(1) .ptsEditArea.ptsInputShell that links to https://www.example.com/form

I'd like to append the URL parameters from the current URL to the button's URL, so that the button's href is now https://www.example.com/form/?firstname=Steven&lastname=Doig&email=steve%40gmail.com&phone=0404555555

How can I do this with JavaScript please?

If you don't care about supporting older browsers you can use the URL API and URLSearchParams.

function appendCurrentUrlSearchParams(anchorElement) {
  const currUrlSearchParams = new URL(window.location.href).searchParams;
  const link = new URL(anchorElement.href);

  // uncomment this line if you want to clear query parameters already present in the anchor url
  // link.search = '';

  for (const entry of currUrlSearchParams.entries()) {
    link.searchParams.append(entry[ 0 ], entry[ 1 ]);
  }
  
  anchorElement.href = link.href;
}

Usage in your case:

appendCurrentUrlSearchParams(document.querySelector('#ptsBlock_553944 .ptsCell:nth-of-type(1) .ptsEditArea.ptsInputShell'));

Use window.location.search:

var url = "https://exmaple.com";
var newurl = url + window.location.search;

newurl will contain all the get (ex. ?something=something&something2=something5) data.

To change the href of a:

var button = document.getElementById('#ptsBlock_553944');
button.href = button.href + window.location.search;

  2. Change the .href of that element to what you want.

function selectFunction() {
    var x = document.getElementById("selectopt").value;

    document.getElementById("mylink").innerHTML = x;
  
    document.getElementById("mylink").href = "http://www." + x + ".com";
  
}

document.location.pathname = '/questions/69240453/appending- 
current-url-parameters-onto-anchor-link/69240510';

//get the document pathname I chose from document.location
let data = document.location.pathname;

let preUrlString = 'www.example.com/form';

let newString = preUrlString + data;
