customvalidator

问题 I've seen docs/websites show that custom validators should go in a /lib or /lib/validators directory of a project. I've found (by reading an answer to another post) that they only seem to work in config/initializers . Does anyone know, or have a pointer to official documentation that shows where custom validators should live? 回答1: If you place your custom validators in app/validators they will be automatically loaded without needing to alter your config/application.rb file. 回答2: If you add

问题 My validations are not working when redirecting from one page to another on passing query string as a parameter with response.redirect or with windows.location.href . When I am redirecting from one page to another page with this: <asp:Button ID="New" runat="server" Text="New" OnClientClick="Transfer()" /> function Transfer() { window.location.href = "Abc.aspx?flag=yes"; //when adding query string my validation doesnt work //window.location.href = "Abc.aspx";// When removing query string my

问题 I'm using the CustomValidationAttribute like this [CustomValidation(typeof(MyValidator),"Validate",ErrorMessage = "Foo")] And my validator contains this code public class MyValidator { public static ValidationResult Validate(TestProperty testProperty, ValidationContext validationContext) { if (string.IsNullOrEmpty(testProperty.Name)) { return new ValidationResult(""); <-- how can I get the error message from the custom validation attribute? } return ValidationResult.Success; } } So how can I

问题 On my page I have a Radio button list and a textbox. The textbox is hidden by default then appears if the user clicks yes. Once they click yes then the textbox must be filled in before they can proceed. I've put in the following code, however it doesn't seem to work at all and when the button is pressed to go to the next page it continues instead of stopping and asking the user to enter something in the box. function Q12iYes() { document.getElementById('txt12i').style.display = "block" }

问题 I have a gridview with three columns of textboxes. It can have as many rows as necessary but its usually only about 5 rows. Each row needs to be validated. I want to create a client side validator that sums 2 of the columns together and compares it with the third column to check that the user has entered the data correctly. Just in case you are wondering, it's part of the spec that the operator must enter the third column rather than simply summing the two previous columns together in the

问题 I implemented a Custom Validator with AJAX, and It works fine: EDITED . Add ASPX code <asp:DetailsView ID="DetailsView" runat="server" Height="50px" Width="25em" DataSourceID="SqlDataSource1" AutoGenerateRows="False" DefaultMode="Insert" CellPadding="4" ForeColor="#333333" GridLines="None" OnItemInserting="DetailsView_ItemInserting"> <Fields> <asp:TemplateField HeaderText="Nombre *"> <InsertItemTemplate> <asp:TextBox ID="txtNombre" runat="server" Text='<%# Bind("nombre) %>'></asp:TextBox>

问题 I've created a model called Term and a validator for it, like this: from django.db import models from django.contrib.auth.models import User from django.core.exceptions import ValidationError def validate_insensitive_exist(value): exists = Term.objects.filter(word__iexact = value.lower()).exists() if exists == True: raise ValidationError("This term already exist.") class Term(models.Model): word = models.CharField(max_length=200, unique=True, validators=[validate_insensitive_exist]) related

问题 I have a couple of columns (ip, provider_id) for which I want combinations of values to always be unique. Therefore, I am trying to build a custom validation function. But I am having issues grabbing on the value of the secondary field. This is my code so far in the model: public $validate = array( 'ip' => array( 'rule' => array('uniqueClick', 'provider_id'), 'message' => 'The click is not unique.' ) ); public function uniqueClick ($ip, $field) { $count = $this->find('count', array(

问题 I've seen a lot of questions about this already, but I'm stumped! Please help! I have a customvalidator. It's firing but it's not preventing postback. Please help me in doing so! I can see that console.log registers before the post. But, it posts back anyway. How do I prevent the postback? I've tried adding a control to validate, and validate empty text equal to true. I also tried adding e.preventdefault, which did not work :( How can I prevent the postback? <script type="text/javascript"> //

问题 I've got a drop-down where the user selects a Country. It is a required "field". Next to it, there is a textfield named State. If the user selects US, then the field State is required. If the user selects e.g. Sweden, the State is not required, since Sweden has no states. Example code: <asp:DropDownList runat="server" ID="Country"></asp:DropDownList> <asp:RequiredFieldValidator ControlToValidate="Country" runat="server" Display="Static" ErrorMessage="Required field" /> <asp:TextBox runat=
