I've got a dynamic forms app and am trying to apply proper unobtrusive validation for the form elements and am having trouble with getting the form to display validation errors the way I want.
My partial view to render the radio button form items looks like this:
@model FormItem
<div class="form-row">
<div class="form-item">@Model.Text</div>
<div class="form-item-responses">
@foreach(FormItemResponse formItemResponse in Model.Responses.OrderBy(x => x.SortOrder))
{
if(Model.Required)
{
@Html.RadioButton(Model.Id.ToString(), formItemResponse.Id, formItemResponse.DefaultSelection, new { @class = "required", data_val = "true", data_val_required = "*"}) @formItemResponse.Text
}
else
{
@Html.RadioButton(Model.Id.ToString(), formItemResponse.Id, formItemResponse.DefaultSelection) @formItemResponse.Text
}
<text> </text>
}
<span class="field-validation-valid" data-valmsg-for="@Model.Id.ToString()" data-valmsg-replace="true"></span>
</div>
Here is the final markup for those not familiar with MVC:
<div class="form-row">
<div class="form-item">Form Item Text Here</div>
<div class="form-item-responses">
<input class="required" data-val="true" data-val-required="*" name="026d44a7-fa55-4fe8-8d2f-4f561c77c716" type="radio" value="dcfa4a9a-53e1-44d5-b6b3-a133673bfa2e" />Yes
<input class="required" data-val="true" data-val-required="*" name="026d44a7-fa55-4fe8-8d2f-4f561c77c716" type="radio" value="0042876b-2362-4f65-9c8a-dddf7f8206e8" />No
<input class="required" data-val="true" data-val-required="*" name="026d44a7-fa55-4fe8-8d2f-4f561c77c716" type="radio" value="a0918eab-93b6-4e45-a78d-301e28571037" />NA
<span class="field-validation-valid" data-valmsg-for="026d44a7-fa55-4fe8-8d2f-4f561c77c716" data-valmsg-replace="true"></span>
</div>
In works in that any group of radio buttons get properly validated, and the *
comes up next to the item. However, what I would like to do is change the text color of everything in .form-item-responses
to red. Not just the validation error message.
How can I do this? I tried using the invalidHandler
like so:
$("#items-form").validate({
invalidHandler: function (form, validator) {
var errors = validator.numberOfInvalids();
console.log(errors);
$("input.input-validation-error").each(function() {
this.parent().css("color", "red");
});
}
});
But that appears to override the default behavior and just put a black This field is required
next to the first radio button in each answer group. I want the default behavior and then just this extra change.
The way I fixed this was getting the validator from the form as a variable, then accessing the settings in document.ready like so:
var validatorData = $('#items-form').data('validator');
validatorData.settings.highlight = function (element, errorClass) {
$(element).parent().parent().css("color", "red");
};
I am not sure why the first way I tried it didn't work. As that seems to be the way in the documentation and on many examples online.
