        <div >
            <input type="text"  value="[email protected]" />

copyText.querySelector("button").addEventListener("click", function () {
    let input = copyText.querySelector("input.text");
    input.select();
    document.execCommand("copy");
    copyText.classList.add("active");
    window.getSelection().removeAllRanges();
    setTimeout(function () {

Use this code for your Substring

const params = new Proxy(new URLSearchParams(window.location.search), {
      get: (searchParams, prop) => searchParams.get(prop),
    });
    // Get the value of "some_key" in eg "https://example.com/?some_key=some_value"
    let value = params.some_key; // "some_value"
