function脚本有错误

想问一下为什呢 validateFileType();中单击按钮不好使

$(document).ready(function(){

	  var reg = /^\d+\.?\d*$/;

     $("#error-floorage").hide();

     $("#error-price").hide();

     $("#floorage").keyup(function(){

        if(reg.test($("#floorage").val())){

           $("#error-floorage").hide();

        }else{

           $("#error-floorage").show();

        }

  });

  $("#price").keyup(function(){

     if(reg.test($("#price").val())){

        $("#error-price").hide();

     }else{

        $("#error-price").show();

     }

  });

  });

  function validate(){

  validateFileType();

  if($("#floorage").val()=='' || reg.test($("#floorage").val())){

      $("#error-floorage").hide();

  }else{

      $("#error-floorage").show();

      return false;

  }

  return true;

  }

  function validateFileType(obj){

      var fileValue = obj !=null ? obj.value : document.getElementById("img").value;

      if(fileValue!=null && fileValue.length>0){

         var suffix = fileValue.substring(fileValue.length -3,fileValue.length);

         if(!(suffix=="jpg"||suffix=="JPG"||suffix=="gif"||suffix=="GIF")){

         alert("请选择jpg格式或gif格式的图片");

         return false;

         }else{

        	 document.getElementById("but").submit();

         }

         

         }

      }
