Remove duplicate 's through jquery

Answer 1

Try -

var seen = {};
$('table tr').each(function() {
  var txt = $(this).text();
  if (seen[txt])
    $(this).remove();
  else
    seen[txt] = true;
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="test">
  <tr>
    <td>test1
      <td>
  </tr>
  <tr>
    <td>test2
      <td>
  </tr>
  <tr>
    <td>test1
      <td>
  </tr>
  <tr>
    <td>test2
      <td>
  </tr>
</table>

Code is taken (and very slightly changed) from this question - JQuery: Remove duplicate elements?

Answer 2

Here you go:

$('#btnRearrange').bind("click", function() {

$("#test td").each(function () {
    var tdText = $(this).text();

    $("#test td")
        .filter(function () { 
            return tdText == $(this).text(); 
        })
        .not(":first")
        .remove();

});
});
