function showYear(ele,options){
  $('body').find('.year-select').remove()
  var date = new Date(),
      nowYear = parseInt(date.getFullYear()),
      year = (parseInt(ele.val()) > 0 ? parseInt(ele.val()) : parseInt(date.getFullYear())),
      years = [],
      yearLeft = ele.offset().left,
      yearTop = ele.offset().top + ele.outerHeight() + 5,
      html = '',
      before_now = options.years_before_now ? options.years_before_now : 30,
      after_now = (options.years_after_now ? options.years_after_now : 10) + 1,
      identifier = Math.floor(Math.random() * 10000000)
  
  ele.attr('year-select-identifier-input', identifier)
  
  while(before_now > 0){
    years.push(nowYear - before_now)
    before_now --
