split按照空格，逗號分割tag

function updateTagInfo(self, updateId, closeId, openId) {
  var s = self.value.replace(//n/g, '<br>');
  var s_space = s.split(/[, ，]/);                                    //   重點在這裡，我還以為要寫n個迴圈呢，原來Regex這麼簡單就能搞定了。

  if(s_space.length>1){
   var html="";
   for(var i=0;i<s_space.length;i++){
    html += "<a href='/search/"+ s_space[i]+ " '>" + s_space[i] + "</a> |";
   }
   $(openId).innerHTML = html;
  }
  else{
   $(openId).innerHTML=
   "<a href='/search/"+ self.value+ " '>" + s + "</a>"
  }
  $(updateId).value = s;
  closeDiv(closeId);
    openDiv(openId);
    if (change) {
     var url = "/cn/album/updatePicture.do";
   var theForm = $("editPicture");
   var pars = Form.serialize(theForm);
   var myAjax = new Ajax.Request( url, { method: 'post', parameters: pars});
  }
  change = false;
