If I understand you, you can achieve that by doing the following:

jQuery:

: $(function(){ // register submit event of the form. $('form.numberValidator').submit(function(){ // check the value of the input field. if ($('input[name="number"]').val() < 20) { alert('The number entered is less than 20.'); return false; // prevent form submission. } }); });

HTML:

: <html> <body> <form class="numberValidator"> <input type="text" name="number" /> <button type="submit">Submit</button> </form> </body> </html>

Try it, if you need help just reply me.
