  • 0

I want to have a form with an input text field and be able to respond (display an alert text box) if the user types in the word ‘hello’ (case insensitive match).

What event do I need to trap (the text input field does not seem to have a change event.

This is what I have so far:

<html>
   <head>
      <title>Some test</title>
      <script type="text/javascript" src="jquery.js"></script>
   </head>
   <body>
      <form action="something.php" method="post">
         Field1: <input id="field1" type="text">
      </form>
<script type="text/javascript">
$(document).ready(function(){
  // what?
});
</script>   
   </body>
</html>

    Try:

    $(document).ready(function(){
  $('#Field1').keypress(function(){
    if ($(this).val() === 'hello'){
      alert('hello entered !!');
    }
  });
});
