Date.prototype.format = function(f){
var d = this

switch (item) {
case "yyyy":
return d.getFullYear()
break
case "MM":
return +d.getMonth() + 1 < 10 ? "0" + (+d.getMonth() + 1) : +d.getMonth() + 1
break
case "dd":
return +d.getDate() < 10 ? "0" + d.getDate() : d.getDate()
break
case "hh":
return +d.getHours() < 10 ? "0" + d.getHours() : d.getHours()
break
case "mm":
