jquery-validate

问题 Do we have any function which returns all the error messages while validating a form? I have tried using the defaultshowerros() function but it returns the error message for the element it is currently validating. How can I get all the error messages of the whole form? 回答1: If you store a reference to the validator, for example: var validator = $("form").validate(); You can call .errors() or .invalidElements() at any time on it, for example: var errors = validator.errors(); //get the error

问题 I'm using jquery for validation in my MVC2 web app (as described here) and I'd like to wire up some callbacks that the jquery validation plugin supports, like invalidHandler, etc. I can manually edit the MicrosoftMvcJQueryValidation.js and add my callbacks (in __MVC_EnableClientValidation, in the options variable) but I was looking for a better approach since that file is used repeatedly and I don't want to have to create one-off copies. A way to manually add an invalidHandler (etc) callback

问题 I have the a form with the following validation setup: $('#form').validate({ onfocusout: false, onkeyup: false, onclick: false, success: function (){ $('#username').addClass('input-validation-confirmation'); } }); $('#username').rules("add", { onfocusout: false, onkeyup: false, required: true, email: true, remote: { url: function, type: 'GET', dataType: 'json', traditional: true, data: { username: function () { return $('#username').val(); } }, dataFilter: function (responseString) { var

问题 With jQueryValidate, I'm trying to make a field required only if another specific field is empty. So, after searching on the Internet, I did this : rules: { marque: { required: { depends: function() { if (($('#add_marque').val() == "Ajouter une marque" && $('#marque').val() == -1) || ($('#add_marque').val() == "" && $('#marque').val() == -1)) { return true; } else { return false; } } } } } Unfortunately, it doesn't work. But, if I do this : depends: function() { if (($('#add_marque').val() ==

问题 I've started to use the jQuery validate plugin. I was having a few issues with the display of the error messages and wanted to create a test page where I could experiment with a few things. Despite the same setup working for me yesterday, I'm now getting the follwing message: this[0] is undefined looking at the jQuery code, it fails in the following section (specific line highlighted): valid: function() { if ( $(this[0]).is('form')) { return this.validate().form(); } else { var valid = true;

问题 Note: the below code is just for demonstration and I am using jQuery and jQuery validate plugin. Suppose I have a form with two fields (email and inventory number): <form action="/something" method="post" id="demoForm"> Inventory No: <input type="text" class="required" name="inventory_no" /> Email: <input type="text" class="required" name="email" /> <input type='submit' value='submit' /> </form> Binding plugin to form: jQuery(function(){ jQuery('#demoForm').validate(); }); //handle user

问题 I'm using a datetimepicker plugin that I found here which works quite well. The only problem now is that it breaks the standard date validation included with the jquery validation plugin because of the added time on the end of the string in the input box. Here is what I have so far in a demo. I added a validation method that checks if the value is a date, but it doesn't accept the time. I need help with writing the custom validation method. How do I split the date and time string and then

问题 I'm using jQuery Validation plugin to validate a form. Do you know how to force revalidation on previously successful fields? I have tried the .form function using the following check (this is performed after the user clicks 'submit'): if ($('#form1').validate().form()==false) { formValid = false; } However, it appears that the code above does not retry validation so fields that are already successfully validated (ie have tick next to them) are not checked again. The reason for wanting to
