2、  ecshop详细页面如何通过onclick点击事件来控制购买，特别用在批发，批发存在一个最小购买量控制．
方法：
         <script>
       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}$/;

方法：date1 = new Date();
var b = Date.UTC(date1.getYear(),date1.getMonth()+1,date1.getDate(),0,0,0)
time1 = frm.elements['best_time'].value;
y = time1.substring(0,4);
m = time1.substring(5,7);
d = time1.substring(8,10);
var b2 = Date.UTC(y,m,d,0,0,0)
8、  如何解析ecshop flash的xml
方法：

   preg_match_all("/link=\"(.*?)\"/",$str,$link);
   $ar_flash = array();
   if(sizeof($url[1])){
    for($i=0;$i<sizeof($url[1]);$i++){
     $ar_flash[$i]['url'] = $url[1][$i];
     $ar_flash[$i]['text'] = $text[1][$i];

$strtest = “yyg中文字符yyg”;
$pregstr = "/([".chr(0xb0)."-".chr(0xf7)."][".chr(0xa1)."-".chr(0xfe)."])+/i";
if(preg_match($pregstr,$strtest,$matchArray)){
echo $matchArray[0];
}
