is it possible to generate a random value (number, symbols, letters) for an input

  • 0

is it possible to generate a random value (number, symbols, letters) for an input field (preferably hidden) on click?
I need to come up with an idea to simulate somewhat of a conformation number. Unfortunately I cant save the values into a db.

I thought of something like:
input before: <input id="randomizeme" value=""/>

javascript or jquery solution:

var randomtext=$('#randomizeme').attr('value');

anybutton.click(){
    randomtext="some numbers randomly scrambled together";


}

input output: 

<input id="randomizeme" value="some numbers randomly scrambled together"/>

this is probably all garbage but i hope it helps, as for the tags im not sure either

    Something like:

    <html>
<head>
    <title>S.O. 4169522</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
    <script type="text/javascript">
    var gRandLength = 7;

    $(document).ready(function() {   
        $('#button').click(function() {   
        var num = Math.floor(1 + (Math.random() * Math.pow(10, gRandLength)));
        $('#input').val(num);
        });
    });
    </script>
</head>
<body onload='onload()'>
    <form>
        <input type="text" value="" id="input" />
        <input type="button" id="button" value="Generate"/>
    <form>
</body>
</html>

    Sample Output:

    alt text
