Setting globalization in jQuery

jQueryGlobalization.js

$(document).ready(function () {
    //Ask ASP.NET what culture we prefer, because we stuck it in a meta tag
    var data = $("meta[name='accept-language']").attr("content")

    //Tell jQuery to figure it out also on the client side.
    $.global.preferCulture(data);

    //Tell the validator, for example,
    // that we want numbers parsed a certain way!
    $.validator.methods.number = function (value, element) {
        if ($.global.parseFloat(value)) {
            return true;
        }
        return false;
    }

    //Fix the range to use globalized methods
    jQuery.extend(jQuery.validator.methods, {
        range: function (value, element, param) {
            //Use the Globalization plugin to parse the value
            var val = $.global.parseFloat(value);
            return this.optional(element) || (val >= param[0] && val <= param[1]);
        }
    });

    //Setup datepickers if we don't support it natively!
    if (!Modernizr.inputtypes.date) {
        if ($.global.culture.name != 'en-us' && $.global.culture.name != 'en') {

            var datepickerScriptFile = "/Scripts/globdatepicker/jquery.ui.datepicker-" + $.global.culture.name + ".js";
            //Now, load the date picker support for this language 
            // and set the defaults for a localized calendar
            $.getScript(datepickerScriptFile, function () {
                $.datepicker.setDefaults($.datepicker.regional[$.global.culture.name]);
            });
        }
        $("input[type='datetime']").datepicker();
    }

});
