how to disable this clickable module after clicking once.....that button should remain disabled after refreshing tha page

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-html -->

<a href="oaccept1.php?id=<?php echo $data['oaid'];?>" class="btn btn-sm btn-primary login-submit-cs" 
onclick="return confirm('Are You Sure')">ACCEPT</a>

<!-- end snippet -->

want to disable that button after accepting that and it should stay disabled after accepting that doc

Use server side, don't depend on only javascript

In table add new field as accepted and make it false by default,

ALTER TABLE `tbl_name` ADD `accepted` BOOLEAN default false;

on click of accept button event function, set this field as true

INSERT INTO `table_name`(id, accepted) VALUES ('2',true );

Then in your php have

<?php  if($data['accepted']==false){?>
  <a href="oaccept1.php?id=<?php echo $data['oaid'];?>" class="btn btn-sm btn-
     primary login-submit-cs" 
     onclick="return confirm('Are You Sure')">
     ACCEPT
  </a>

<?php }else {?>

 <a  class="btn btn-sm btn-
     primary login-submit-cs" 
     disabled>
     ACCEPT
  </a>
<?php }?>

hope this will help you

I suggest you make it a button, otherwise a simple visit from a google bot will accept all

Alternative is to use a form submit event

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

window.addEventListener("DOMContentLoaded", () => {
  const sub = document.querySelector(".login-submit-cs");
  const dis = false; //  localStorage.getItem("submitted"); // remove "false; //" to activate
  if (!dis) sub.removeAttribute("disabled");
  sub.addEventListener("click", (e) => {
    let  tgt = e.target.closest("button"); // using closest in case the element has children
    if (!tgt || dis) return; // not the link
    setTimeout(() => tgt.setAttribute("disabled","disabled"),200); // allow the button to be pressed
    // localStorage.setItem("submitted",true); // remove comment lines to activate
    location = tgt.dataset.href;
  });
});

<!-- language: lang-html -->

<button data-href="oaccept1.php?id=<?php echo $data['oaid'];?>" class="btn btn-sm btn-primary login-submit-cs" disabled>ACCEPT</button>

<!-- end snippet -->
