juery同时判断多个输入框是否为空
例如：
< /script>
function login() {
if(!submitValid())return;
$.ajax({
url:”manager/*“,
type:”post”,
dataType: “json”,
data: $(“#form”).serialize(),
success:function(data){
var resultData = data; //eval(“(“+data+”)”);
if(resultData.result == “success”)
{
//window.top.location.href=”manager/**“;
window.location.href=”manager/*“;
}
else
{
alert(resultData.error);
}

            },error:function(data){                alert("error");            }        });    }    function submitValid(){          var resultFlag = true;          var errorFlagCount = 0;          resultFlag = checkInputEmpty('manager_id');          if(resultFlag == false){            errorFlagCount++;          }           resultFlag = checkInputEmpty('password');          if(resultFlag == false){            errorFlagCount++;          }           if(errorFlagCount > 0)          {            return false;              }          return true;        }        function checkInputEmpty(id){             var tempObjVal=$("#"+id).val();          if(tempObjVal=='undefined' || tempObjVal==null || $.trim(tempObjVal).length==0){             //$("#"+id+"Msg").html('*必填');             $("#"+id+ "Msg").css("visibility","");             return false;          }else{             //$("#"+id+"Msg").html('');              $("#"+id+ "Msg").css("visibility","hidden");             return true;          }         }
