<script type=text/javascript>

function validate() {

    if (document.form.price.value.trim() === ) {

        alert(Please enter a price);

        document.form.price.focus();

        return false;

    }

    if (document.form.price.value !== ) {

        if (! (/^d*(?:.d{0,2})?$/.test(document.form.price.value))) {

            alert(Please enter a valid price);

            document.form.price.focus();

            return false;

        }

    }

    return true;

}

</script>



<form action= method=post name=form id=form onsubmit=return validate(this);>



<input name=price  type=text class=r2 />

<input name=price2 type=text class=r2 />

<input name=price3 type=text class=r2 />

<input name=price4 type=text class=r2 />

<input name=price5 type=text class=r2 />

...more....

<input name=price50 type=text class=r2 />

This javascript code is working fine to validate the field price.

Question :

How to make the code to work as global validation? Example: would validate the price, price2, price3, price4, price5 etc.. with a single function. Please let me know :)
