    jQuery – find total number of DOM elements

    By admin on Jan 18, 2016

    To get total DOM elements including children use the following code (this includes root html element also)

    $('*').length
    

    To get all DOM elements in body (excludes body itself)

    $('body *').length
    

    Here is sample code:

    <html>
    <head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
    </head>
    <body>
    <div id="count1">-</div>
    <div id="count2">-</div>
    <script type="text/javascript">
      var str1= $('*').length;
      var str2= $('body *').length;
      str1 += " => ";
      str2 += " => ";
      $('*').each(function(){
        str1 = str1 + this + " | ";
      });
      $('body *').each(function(){
        str2 = str2 + this + " | " ;
      });
      $('#count1').text(str1);
      $('#count2').text(str2);
    </script>
    </body>
    </html>
    refresh done
    try it online
