Answer 1

how about this one

var progessss = $('#progressBar');
progessss.animate({
    'width':'+=80%'
},1000);

setTimeout(function(){
    progessss.animate({
        'width':'0%'
    },1000);
},5000)

Answer 2

You can use setTimeout for this

setTimeout(function(){ progessss.animate({
    'width':'0%'
},1000); }, 4000);
