Delete the originally selected user record list (equivalent to clearing operation)
Add new selected user record list
Page

1 Save shared file

// 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;
        }
