js获取div中的文本框数据

通过div得到div里的所有数据

大神的世界无需解释，当然不是说我，当我看到这些代码的时候我惊呆了！

这是一个工具方法js：

js:

 /*
     * 获取指定对象下的所有input、textarea值
     * divid：外层的id
     * jsonStr：如果无，新创建一个对象，如果有，直接在对象中添加
     * isCheck:是否进行必填项判断
     */
    getFormParam: function(divid,jsonStr,isCheck){
        var inputlist = $("#"+divid+" input[type=text]");
        var textarealist = $("#"+divid+" textarea");
        var param = {};
        if(jsonStr){
            param = jsonStr;
        }

        var iserror =false;
        $.each(inputlist,function(i,obj){
          var id = obj.id;
          var name = obj.name;
          if(!id && !name){

          }else{
              var ligeruiid = obj.attributes.ligeruiid;
              var val = $.trim(obj.value);
              if(val == ''){
                  if(isCheck && $(obj).attr("isrequired") == ''){
                      if(obj.style.display == 'none' || (obj.parentNode && obj.parentNode.style.display == 'none')){//父节点是否隐藏

                      }else{
                          iserror =true;
                          obj.style.border = '1px dotted #FF0000';
                          //$(obj).attr({"style":"border: 1px dotted #FF0000;"});
                      }
                  }
              }else{
                  obj.style.border = '';
              }
              if(ligeruiid){
                  val = $("#"+id+"_hidden").val();
              }
              if(name){
                  param[name] = val;
              }else{
                  param[id] = val;
              }
          }
        });
        $.each(textarealist,function(i,obj){
          var id = obj.id;
          var name = obj.name;
          if(!id && !name){

          }else{
              var val = $.trim(obj.value);
              if(val == ''){
                  if(isCheck && $(obj).attr("isrequired") == ''){
                      if(obj.parentNode && obj.parentNode.style.display == 'none'){//父节点是否隐藏

                      }else{
                          iserror =true;
                          obj.style.border = '1px dotted #FF0000';
                          //$(obj).attr({"style":"border: 1px dotted #FF0000;"});
                      }
                  }
              }else{
                  obj.style.border = '';
              }
              if(name){
                  param[name] = val;
              }else{
                  param[id] = val;
              }
          }
        });
        if(iserror){
            return 'error';
        }
        return param;

将div里的值获取后传向后台：

var jsonStr;

jsonStr = globalUtil.getFormParam('main_t',null,false);
        $("#tb_btn").css("display","none");//隐藏按钮
        $.post(globalUtil.getTimestampUrl("/cremanage/mcscrecreditheadupdate.do"),
                jsonStr, function(data) {
                    if (data === 'OK') {
                        globalUtil.successMsg(globalErrorMsg[''],
                                function() {
                                    //关闭TAB 刷新列表
                                    closeTabAndRes();
                                });//保存成功
                    }else {
                        globalUtil.errorMsg(globalErrorMsg['']); //保存失败
                        $("#tb_btn").css("display","");//显示按钮
                    }
                });
