I want to clear the values of a certain table so I want to get the table name using Bootstrap modal. I want the name of the table in url.

This is my code: Here I'm sending the name of the table into the modal

<ol class="breadcrumb text-center">
  <li class="breadcrumb-item">
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product1">Insert1</a>
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product2">Insert2</a>
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product3">Insert3</a>
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product4">Insert4</a>
</ol>

I want to pass the value inside data-table into href as clear.php?clear_id="table_name" 

<div class="modal fade" id="scrapModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel1" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel1">Confirm Clear?</h5>
        <button class="close" type="button" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">×</span>
        </button>
      </div>
      <div class="modal-body">Are you sure you want to clear scrap for this table.</div>
      <div class="modal-footer">
        <button class="btn btn-secondary" type="button" data-dismiss="modal">Cancel</button>
        <a class="btn btn-danger" href="clear.php?clear_id=">Clear</a>
      </div>
    </div>
  </div>
</div>

Thank you in advance!

You can dynamically change the href value of the Clear button in your modal by utilising the shown.bs.modal event trigger and building the URL with the data-table attribute at your disposal provided by the relatedTarget property in the event object.

I've add a clear button click event to emphasise this visually.

$('#scrapModal').on('show.bs.modal', function (e) {
  var table = $(e.relatedTarget).data('table')
  var href = 'clear.php?clear_id=' + table
  $('.btn-danger', this).attr('href', href)
  console.log(href)
})

// Simulate "clear" button click to alert href value
$('#scrapModal .btn-danger').on('click', function (e) {
  e.preventDefault()
  alert(e.target.pathname + e.target.search)
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" rel="stylesheet"/>

<ol class="breadcrumb text-center">
  <li class="breadcrumb-item">
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product1">Insert1</a>
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product2">Insert2</a>
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product3">Insert3</a>
     <a class="btn btn-primary" href="#scrapModal" data-toggle="modal" data-table="product4">Insert4</a>
  </li>
</ol>

<div class="modal fade" id="scrapModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel1" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel1">Confirm Clear?</h5>
        <button class="close" type="button" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&#215;</span>
        </button>
      </div>
      <div class="modal-body">
        Are you sure you want to clear scrap for this table.
      </div>
      <div class="modal-footer">
        <button class="btn btn-secondary" type="button" data-dismiss="modal">Cancel</button>
        <a class="btn btn-danger" href="#">Clear</a>
      </div>
    </div>
  </div>
</div>

Use the following lines of code inside your script tag and this should work fine.

$('#scrapModal .btn-danger').on('click', function (e) {
  e.preventDefault()
  alert(e.target.pathname + e.target.search)
})

You can do it by using a simple script like this:

$('#scrapModal').on('show.bs.modal', function (event) {
  var table = $(event.relatedTarget).data('table');
  $(this).find('.btn-danger').attr("href", "clear.php?clear_id=" + table);
)}

This will run when the modal appears. It would be better to give the confirm button an id attribute in order to look up in a more elegant way.
