       function adgtz(){
      var number = document.getElementById("ordernumber").value;
      var min_number = {$goods.min_number};
      var goods_num = 1000;
      if(number > goods_num - min_number){
   alert("最多能买"+goods_number+"件");
      }
      number=parseInt(number)+min_number;
      document.getElementById("ordernumber").value = number;
}
function adgtzmm(){
    var number = document.getElementById("ordernumber").value;
     var min_number = {$goods.min_number};
    if (number>min_number){
      number=parseInt(number)-min_number;
    }
    document.getElementById("ordernumber").value = number;
   
}
</script>

3、  如何用js去验证手机号码．

方法：var reg =/^[1]([3][0-9]{1}|50|53|59|58|56|86|80|89|87|88|85|86|55|51|52|57)[0-9]{8}$/;

time1 = frm.elements['best_time'].value;

y = time1.substring(0,4);
m = time1.substring(5,7);

    for($i=0;$i<sizeof($url[1]);$i++){
     $ar_flash[$i]['url'] = $url[1][$i];
     $ar_flash[$i]['text'] = $text[1][$i];
