Dependency

• Requires Knockout
• jQuery (for setting text())
• ASP.NET (for the formatting functions).

 

ko.bindingHandlers.date = {
    update: function(element, valueAccessor, allBindingsAccessor) {
        var value = valueAccessor(), allBindings = allBindingsAccessor();
        var valueUnwrapped = ko.utils.unwrapObservable(value);
       
        var d = "";
        if (valueUnwrapped) {
            var m = /Date\([\d+-]+\)/gi.exec(valueUnwrapped);
            if (m) {
                d = String.format("{0:dd/MM/yyyy}", eval("new " + m[0]));
            }
        }       
        $(element).text(d);   
    }
};
ko.bindingHandlers.money = {
    update: function(element, valueAccessor, allBindingsAccessor) {
        var value = valueAccessor(), allBindings = allBindingsAccessor();
        var valueUnwrapped = ko.utils.unwrapObservable(value);
       
        var m = "";
        if (valueUnwrapped) {       
            m = parseInt(valueUnwrapped);
            if (m) {
                m = String.format("{0:n0}", m);
            }
        }       
        $(element).text(m);   
    }
};

Usage:

 

• data-bind="money: myMoney"
• data-bind="date: myDate"

 

Note:

Dates are converted from ASP.NET's date format: \/Date(1000+1000)\/
