Code working in IE and Chrome doesn't work in Firefox

I made jQuery function that allows only numbers and one point in input type=text.

It works in IE and Chrome, but doesn't in Firefox. Can anyone help?

Here is the code:

$(document).ready(function () {
$(".inputbox").keypress(function (e) {

    //Allow only one point  
    if (String.fromCharCode(e.keyCode).match("[.]") && this.value.indexOf(".") != -1) {
        return false;
    }
    //Allow just numbers
    if (String.fromCharCode(e.keyCode).match(/[^0-9.]/g)) {
    return false;
    }

    return true;
});
});

The problem isn't in the regular expression but in e.keyCode. Some browsers use keyCode, others use e.which.

jQuery handles this browser difference for you, making sure that e.which works cross-browser.
