Trigger search on clicking on textbox

Hi,

Theoretically, it should be possible with some custom script code. Try copying this code to the functions.php in your theme (or child theme) directory:

Please make sure to have a back-up of your site before making any direct changes on your server!

add_filter('wp_footer', 'asl_trigger_input_click', 10);
function asl_trigger_input_click() {
  ?>
  <script>
  jQuery(function($) {
    $('input.orig').on('click', function(e) {
      var _e = jQuery.Event("keyup");
      
      e.preventDefault();
      if ( $(this).val() == '' )
        $(this).val(' ');
      _e.keyCode = _e.which = 50;      
      if ( typeof window.event != 'undefined' )
        window.event = null;    
      $(this).trigger(_e);
    });
  });
  </script>
  <?php
}

This code will add an event handler for the input click, to trigger the search process.
