我使用上面，形成验证并提交，验证空的工作，并同时警告"OK"提交按钮也提交，它不应该提交，防止表单提交我使用jQuery来防止表单提交当无法验证失败处理此请求..如何如果验证失败

我的主要问题是，当验证失败的形式不应submit..if验证失败时说：确定自动提交的按钮时，我收到警报消息..

的onsubmit返回false –

你真的应该看看使用jQuery验证。它将解决您的问题，并将所有代码转换为大约10行。 –

你可以编辑你的问题来突出你的问题。 – Anil

Jquery.validate是最好的方法提交

尝试此之前，验证所有字段：

<script> 

    $("#form").validate({ 
     errorElement: "em", 
     errorPlacement: function (error, element) { 

      $(element.parent("div").addClass("form-animate-error")); 
      error.appendTo(element.parent("div")); 
     }, 
     success: function (label) { 
      $(label.parent("div").removeClass("form-animate-error")); 
     }, 
     rules: { 
      txtTitle: "required", 
      validate_lastname: "required", 
      validate_username: { 
       required: true, 
       minlength: 2 
      }, 
      validate_password: { 
       required: true, 
       minlength: 5 
      }, 
      validate_confirm_password: { 
       required: true, 
       minlength: 5, 
       equalTo: "#validate_password" 
      }, 
      validate_email: { 
       required: true, 
       email: true 
      }, 
      validate_agree: "required" 
     }, 
     messages: { 
      City: "Please select city", 
      PropertyType: "Please select property type", 
      // ParkingType: "Please select parking type", 
      validate_firstname: "Please enter your firstname", 
      validate_lastname: "Please enter your lastname", 
      validate_username: { 
       required: "Please enter a username", 
       minlength: "Your username must consist of at least 2 characters" 
      }, 
      validate_password: { 
       required: "Please provide a password", 
       minlength: "Your password must be at least 5 characters long" 
      }, 
      validate_confirm_password: { 
       required: "Please provide a password", 
       minlength: "Your password must be at least 5 characters long", 
       equalTo: "Please enter the same password as above" 
      }, 
      validate_email: "Please enter a valid email address", 
      validate_agree: "Please accept our policy" 
     } 
    }); 
</script>
