發現12306餘票查詢頁面的js代碼，看不懂啊？OUT了！

<script type="text/javascript">
  if(3!=6){
  var dd3 = new dhtmlXCombo("nday3","nday3",40);
  dd3.setOptionHeight(230);
  dd3.setComboValue(fDay());
  dd3.readonly(true);
  getOptionDay3();
  dd3.selectOption(dd3.getIndexByValue(fDay()),"true","true");
     

  }  
  if(3==6){
  var dd3 = new dhtmlXCombo("nday3","nday3",40);
  dd3.setOptionHeight(230);
  dd3.setComboValue(fDay6());
  dd3.readonly(true);
  
  dd3.selectOption(dd3.getIndexByValue(fDay6()),"true","true");
  
  getOptionDay3();
  }
