I'm using jQuery validation engine for field validation
On page load there are already fields available, and the validation works correct
for them, but there are some buttons which add fields dynamically, and those
validations won't work obviously :) I tried initializing the instance again but it
doesn't work.
Is there a method by which I can manually add validation instance to those field which
I have added dynamically
EDIT: Sorry forgot to mention, I'm using this plugin

Thanks,

This article helped me very much: http://xhalent.wordpress.com/2011/01/24/applying-unobtrusive-validation-to-dynamic-content/
You should validate a container in which you have dynamically added elements

So, I'm having a little issue here with angular and forms
I'm creating a dynamic form, and it works correctly, but I needed to add some validations.
So I started to follow this guide and I set it up correctly, but when I set the form tags to surround my form controls, I'm getting a blank form
But, if I comment the form tags, I get my form perfectly
Any idea of why this is happening???
I have a couple of validation to show fields based on values, like
custConfig is part of the scope, could the name of the form be interfering with the retrieval of the custConfig variable? and if its such, how can I fix this?
Thanks
Your using a repeater
ng-repeat="deliver in shipmentDetails"
Do you have anything in your object shipmentDetails array? if not then the form will not show anything
I have a form with many different input fields (some of them are not really input but behave as inputs).
When submitting the from from the regular button click each field is validated through angular validation and html - such as required, ng-maxlength, minlength, etc..
Now we want to add a shortcut to submit the form on keyboard click. That code is running from the controller behind the html. How can I check the validity of the form from there? I know I can get the form by document.forms["myForm"] but can I use that somehow to check the validity same way as .$valid is working in the html? Could I somehow show the error messages on the html as well?
I tried to add jQuery validation plugin for that but seems like it is too much work to change the entire validation mechanism
Don't get the form withdocument.forms["myForm"]".
It's bad practice to use DOM manipulation inside a controller.
You can access the form with $scope.myForm. But beware of the fact that it will be initialised asynchronously.
But that shouldn't be a problem when you want to access the form after a keyboard click.
When you access the form with $scope.myForm you can iterate throw the $$controls. In this object are all form fields.
For example you can do it like this:
angular.forEach($scope.myForm.$$controls, function(value, key) {
value.$setDirty();
value.$setTouched();
});
And one more reminder when you use angular don't try do use JQuery for everything. If you want to use plugins search for angular plugins
I have a situation where i have to modify a form (to dynamically add a table) via jquery after it's been rendered / created.
The problem is that when the form is submitted, and redisplayed because of errors or validation issues, I don't know of a good way to save and redisplay the data they've entered into the fields I've created dynamically.
Any suggestions would be appreciated.
You probably want to use something like jQuery Populate.
Dynamically added data don't differ from the static added ones. You have to use 'validate()' method to prevent submitting and rendering the html-code with errors, in this case user will see the dynamically added data.
I am working on a project that use MVC 2.0 with Kendo UI. We decided to use AJAX validation instead of MVC Model level validation; which means validation happens during most "onchange" events on HTML controls. We coded the red CSS "highlight" on HTML controls when error happens and remove the highlight when there is no error. If there are multiple controls (e.g. checkboxes) we will highlight all of them when error occurs...and of course, error messages related to multiple fields validaton....
We get it sort of working but we had to implement a lot of javascript/jQuery coding on each web form page (including control id/name matching on the validation message) and does not seem to be able to implement it as a common routine against all web forms. We are also wondering if there is some sort of validation library already out there that more or less achieving the same thing...
Any suggestions?
If you tag your question with kendo-ui you are probably using it so it might be worthy taking a look into kendo.ui.Validator
You should try jQuery Validation
Its very easy to use, but you do still need to link each input to they type of validation required
I want a class in JavaScript through which I can validate all the Input Boxes on a form. I just want to supply the form name and it must validate the input boxes there in.
Is there any class or something other through which I can achieve this?
Have you looked at the validator plugin?
http://docs.jquery.com/Plugins/Validation
If you don't want to use JQuery I described an alternative library in an earlier post
What JavaScript library to use for client-side form checking?
That allows you to just add attributes like REQUIRED or DATE to an <INPUT> tag.
It's a bit old-hat now, but we are still using it in production :)
