我尝试使用JQuery添加了两个选择器，但是内容没有显示出来，如果只添加一个选择器，那么它可以正常工作，所以请你帮我解决这个问题，以下是代码

这个脚本的想法是显示燃油价格（燃料和柴油），有3种类型的燃料和1种柴油 第一个选择器按数字显示价格，第二个选择器按月份显示价格图表。

jQuery(function($) {
  var selects = $('select');
  var values = '';
  selects.each(function() {
    values += '.' + $(this).val();
  });
  $(values).show();
  $('select').on('change', function(index, value) {
    if ($('#SelectOne').val() == 'Diesel') {
      $('#SelectTwo').prop('disabled', true);
    } else {
      $('#SelectTwo').prop('disabled', false);
    }
    $('#results_container > div').hide();
    var values = '';
    selects.each(function() {
      values += '.' + $(this).val();
    });
    $(values).show();
  });
});

jQuery(function($) {
  var selects = $('select');
  var values = '';
  selects.each(function() {
    values += '.' + $(this).val();
  });
  $(values).show();
  $('select').on('change', function(index, value) {

    $('#results_chart > div').hide();
    var values = '';
    selects.each(function() {
      values += '.' + $(this).val();
    });
    $(values).show();
  });
});

#results_container>div,
#results_chart>div {
  display: none;
}

.result {
  padding-top: 10px;
}

.dif,
.difp {
  display: inline;
  padding-left: 15px;
  color: red;
}

.arrow {
  transform: rotate(-135deg);
  -webkit-transform: rotate(-135deg);
  border: solid Red;
  border-width: 0 3px 3px 0;
  display: inline-block;
  padding: 3px;
  margin-left: 10px;
}
