How to hide a ribbon in SharePoint 2010/2013/Online using Jquery

This post explains how to hide a SharePoint Ribbon in SP 2010/2013/ SP Online using jquery.
It is very simple jquery code to hide the ribbon.
For example say suppose you want to hide Add New Item Ribbon in a List called Contacts.
Here is how efficiently we can achieve this.

$(document).ready(function () {
    var currentPage = decodeURIComponent(window.location.href.replace(/\+/g, " "));
    if (currentPage.contains("Lists/Contacts")) {
      window.setTimeout(hideRibbon, 500);
    }
});
function hideRibbon() {
    $('span[id^="Ribbon.ListItem.New.NewListItem"]').hide()
    window.setTimeout(hideRibbon, 200);
}

Above simple jquery code does the trick. As you can see, if the url is lists/contacts, we are calling the method  hideRibbon with a delay. And in the hideRibbon method we are calling the same method again with a delay. which will keep hiding the ribbon.

Happy coding :)
