jquery实现保存已选用户

// 保存共享文件  function shareFile(){    // 参数    var signid = chooseObj.id;    var objtype = chooseObj.type;    var userlist = "";    $("input[name=shareUserId]").each(function(){       // 此时的this 就是那个 html中的 那个checkbox对象。所以通过       // this.checked 直接访问属性都是可以的        if($(this).attr('checked')){         userlist = userlist+$(this).val()+","       }    });    if(userlist.length>0){      userlist = userlist.substring(0, userlist.length-1)    }    $.ajax({      url : '../share/shareFile.do',      //url:'${ctx}/index.jsp',      cache : false,      type : 'post',      dataType : 'html',      async : false,      contentType : "application/x-www-form-urlencoded;charset=utf-8",      data : {        'signid' : signid,        'objtype' : objtype,        'userlist':userlist      },      success : function(ret) {        // 异常处理        if(ret==3){          handleWarm("目标文件夹是自己");           return;        }else if(ret==2){          handleWarm("不能移动至子目录");           return;        }         // closeflowcontent('fxcontentflow');        refreshThisContent();      }    })  }
