In my code whenever we click this button counting apply on all user but I want each user to see their own button clicked count.

Is this possible in local storage or I have to use php ?

function refreshDiv() {
  if (localStorage.clickcount) {
    localStorage.clickcount = Number(localStorage.clickcount) + 1;
  } else {
    localStorage.clickcount = 1;
  }
  document.getElementById("count").innerHTML = localStorage.clickcount;
}

<button id="txt-btn" class="dropdown-item" onclick="refreshDiv();">Save</button>
<table class="w3-table-all w3-card-4">
  <tr>
    <th>count</th>
  </tr>
  <tr>
    <td id="count"></td>
  </tr>
</table>
