Could someone provide a good tutorial on how may I validate my html fields with unobtrusive, but without using MVC helpers. Is it possible at all?
I would like to keep the plain html and use input type="text"
field instead of mvc helpers <%= Html.TextBox("Name") %>
but still using the model validation..
public class Employee
{
[Required]
public string Name { get; set; }
}
Also is it possible with jquery Ajax?
Thanks
While it is possible to perform unobtrusive validation in MVC without using helpers, it will be painfully for you as developer to do it manually without usage of mvc helpers. Saying strictly, it will kill your performance and make your code unreadable.
Basically, unobtrusive validation consists of two parts: server side, via data-attributes to your model fields and MVC Helpers, which generate necessary markup, and client side library, jquery.validate.unobtrusive.js, which parses those markup to meaningful parts for jquery validate plugin.
So, in general, you can manually write necessary markup, as long as validation js library will be loaded, validation will work. For example, field, which is subject of validation, must be marked with data-val='true' attribute. If you want to make your field required, you should write additionally something like data-val-required="error message". For length validation - data-val-length-min="5" (obviously, minimum) data-val-length-max="50" (maximum length), data-val-length="Min 5 max 50 chars required".
While, when using normal mvc approach, it is just a question of model attribute:
[Required]
[StringLength(50, MinimumLength = 5)]
public string Name { get; set; }
and one line of code in markup:
@Html.TextBoxFor(o=>o.Name)
Nice, shiny, separates View and Model, and helps KISS.
And for second part of your question. If I understood your problem correctly, you want to validate dynamic forms. Probably it will be answer: jquery.validate.unobtrusive not working with dynamic injected elements
