Welcome to TSDN.

You can simply use <script>some JavaScript code</script> as you use in other Markup Language.

Kind regards,

Changed thread title to better describe the problem (did you know that threads whose titles do not follow the Posting Guidelines actually get FEWER responses?).

Use regular expressions. Try, e.g.

/^[-0-9]+$/

Hi,
use following function that will allow only digits.....

function onlyDigit(e)
{    
    var unicode=e.charCode? e.charCode : e.keyCode            
    if (unicode!=8 && unicode!=9 && unicode!=46 && unicode!=39 && unicode!=37)
    { 
        if((unicode<48||unicode>57) && (unicode<96||unicode>105))
        return false
    }                                
}

Instead of all that code, you'll find a simple regular expression to be better.
