Social Share Buttons on WordPress without Plugin

Currently, so many social sharing plugins are available in the WordPress plugin directory, but  the use of too many plugins reduces the website speed. Here I will help you to add a simple social sharing without any plugin. Please copy paste this code into your WordPress theme php file (example page.php, single.php, custom page, archive page (within loop code) ) file.

  $.fn.customerPopup = function (e, intWidth, intHeight, blnResize) {
    
    // Prevent default anchor event
    e.preventDefault();
    
    // Set values for window
    intWidth = intWidth || '500';
    intHeight = intHeight || '400';
    strResize = (blnResize ? 'yes' : 'no');

    // Set title and open popup with focus on it
    var strTitle = ((typeof this.attr('title') !== 'undefined') ? this.attr('title') : 'Social Share'),
        strParam = 'width=' + intWidth + ',height=' + intHeight + ',resizable=' + strResize,            
        objWindow = window.open(this.attr('href'), strTitle, strParam).focus();
  }
  
  /* ================================================== */
  
  $(document).ready(function ($) {
    $('.customer.share').on("click", function(e) {
      $(this).customerPopup(e);
    });
  });
    
}(jQuery));
