Answer 1

Try this.

var i=0,
navNames = ['home_icon', 'fav_icon', 'recent_icon', 'setting_icon'];

$('.myNavBar').find('li').each(function(){
    $(this).children('a').attr('id', navNames[i])
    i++;
});

Fiddle Demo

Try this approach to put text too on navigation bar.

var i=0,
 navNames = {
                'Home': 'home_icon',
                'Favorites':'fav_icon',
                'Offers': 'recent_icon',
                'Settings': 'setting_icon'
            };

$.each(navNames, function(index, value){
    $('.myNavBar').find('li:eq('+i+')')
    .children('a').attr('id', value)
    .end().children('a').text(index);
    i++;
});

Answer 3

All above answered ways are right but, in the above solutions icons of tab hide and only it shows updated text. The right way to do this is $($('.ui-btn-text')[0]).html('testing');. It will change the name of first tab Home to testing.
