    $('.search_textbox').val('');

Answer 1

in your $(document).ready(function() { try this:

var updateTextboxes = function () {[...]}
$('#query').change(updateTextboxes);

Your code:

<input onkeydown="updateTextboxes()" class="search_textbox" autocomplete="off" type="text" name="search" id="query" />

doesn't work because the function updateTextboxes isn't in the main scope

Answer 2

You are getting a updateTextboxes() not defined error. Remove onkeydown="updateTextboxes()" from your html code and add this to your jquery function:

$('.search_textbox').on('keydown', function(){

      updateTextboxes()  
})

here is the fiddle: http://jsfiddle.net/Su9Uv/

Answer 3

$('#query').on('change', updateTextboxes);


$('#query').on('input', updateTextboxes);

• Listening for the "input" event will trigger any time the input is modified (Even on paste).

  Note: The "Input" event should only be used if legacy browser support is not an issue.
