Mixing asp mvc3 unobtrusive validation with jquery validation plugin

For asp mvc3 client side validat开发者_运维百科ion, is it possible to mix the default, out of the box unobtrusive style with the jquery validation plugin?

This is the form in the view :

@using (Html.BeginForm("", "", FormMethod.Post, new { id = "newRatingForm" }))
{   
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>Rating</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.Rate)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Rate)
            @Html.ValidationMessageFor(model => model.Rate)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Email)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Email)
            @Html.ValidationMessageFor(model => model.Email)
        </div>

        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

Unobtusive works great by default using the usual validation attributes on the properties of the model . The goal is to replace the 'model.Rate' bits in the form with [fyneworks][1] jquery star rating plugin and use the jquery validation plugin just for that part of the form:

<span>Your Rating:</span>
<div id="ratingStars">
    <input class="star {split:2}" type="radio" name="Rating" value="0.5"/>
    <input class="star {split:2}" type="radio" name="Rating" value="1.0"/>
    <input class="star {split:2}" type="radio" name="Rating" value="1.5"/>
    <input class="star {split:2}" type="radio" name="Rating" value="2.0"/>
    <input class="star {split:2}" type="radio" name="Rating" value="2.5"/>
    <input class="star {split:2}" type="radio" name="Rating" value="3.0"/>
    <input class="star {split:2}" type="radio" name="Rating" value="3.5"/>
    <input class="star {split:2}" type="radio" name="Rating" value="4.0"/>
    <input class="star {split:2}" type="radio" name="Rating" value="4.5"/>
    <input class="star {split:2}" type="radio" name="Rating" value="5.0"/>
</div>

I've hijacked the submit action for the form and converted form values to Json to do an ajax request with :

$("#newRatingForm").submit(function (event) {
    event.preventDefault();

    if ($(this).valid()) {        
        newRatingSubmit();
    }    
}); 

function newRatingSubmit() {
    //jquery ajax request using form values converted to Json
}

Radio buttons seem to break the form and the hijack code no longer works i.e. when I click submit, no request is made to server (watching on firebug console) and the form just disappears. Again, it all works fine with just plain mvc3 form.

I tried adding a jquery validation rule for the rating radio buttons but didn't seem to make any difference :

$("#newRatingForm").validate({
    meta: "validate", 
    errorLabelContainer: "#ErrorDiv",
    wrapper: "div",
    rules:
    {
        Rating: {
            required: true
        }
    },

    messages:
    {
        Rating: {
            required: 'A Rating required.'
        }
    },

    onfocusout: false,
    onkeyup: false,

    //handle validation ok, POST submit
    submitHandler: function (label) {
        newRatingSubmit();
    }
 });

As an alternative I can validate a standard html form using the star rating plugin using the jquery validation plugin and submit that with the above code but that doesnt seem very 'asp.net mvc'. For example I then need 2 sets of validation messages - 1 for the server using validation attributes and another for the client view.

jQuery.validator.addMethod("methodeName", function (value, element, params) {
        if (somthing) {
            return false;
        }
        return true;
    });

    jQuery.validator.unobtrusive.adapters.addBool("methodeName");

and in html add 2 attributes

dal-val = true and dal-val-methodeName="errorMessage"

As suggested by @Vadim, I decorated the star rating controls of my form with data-val="true" data-val-required="Please enter your rating" as in ;

<div id="ratingStars">
        <input class="star {split:2}" type="radio" name="Rating" value="0.5" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="1.0" data-val="true"data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="1.5" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="2.0" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="2.5" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="3.0" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="3.5" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="4.0" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="4.5" data-val="true" data-val-required="Please enter your rating"/>
        <input class="star {split:2}" type="radio" name="Rating" value="5.0" data-val="true" data-val-required="Please enter your rating"/>
    </div>
    <span data-valmsg-replace="true" data-valmsg-for="Rating" class="field-validation-valid" style="display:block; width:80px"></span>

I dont need a custom validator I think as the jquery default 'required' validator will do fine. This kinda works. However, the 1st time I click submit I get the exact result Im hoping for;

If I then select a rating and click submit again (without , say, inputting an email) the form just 'disappears' from view and my controller is not hit.

If I replace the radio buttons with a plain text box instead to accept the rating;

<input type="text" name="Rating" id="Rating" data-val-required="Please enter your rating" data-val="true" class="text-box single-line"/>

it works great and my controller is hit when I click submit. Text box no good for the rating though unfortunately.
