I am doing form validations in vuelidate. I have a date picker in my form which is not a mandatory field. Yet I cannot submit the form without selecting a date from the date picker. How is it so? Can anyone tell me how to fix it? I want to keep the date picker field as not a mandatory field. Here is my code:
<v-menu ref="menu3" :close-on-content-click="false" v-model="anniversaryVisibility" :nudge-right="10" :return-value.sync="enquiryForm.anniversary"
lazy
transition="scale-transition"
offset-y
full-width
min-width="290px">
<v-text-field
slot="activator"
v-model="enquiryForm.anniversary"
label="Anniversary"
append-icon="event"
outline
readonly
:error-messages="fieldErrors('enquiryForm.anniversary')"
#input="$v.enquiryForm.anniversary.$touch()"
#blur="$v.enquiryForm.anniversary.$touch()"
>
</v-text-field>
<v-date-picker v-model="enquiryForm.anniversary" #input="$refs.menu3.save(enquiryForm.anniversary)"></v-date-picker>
</v-menu>
Can I see the stuff inside the <script> tags?
I'm assuming inside you have something like this
validations: {
fields: {
anniversary: required
}
}
So you would have set anniversary to required, you just need to delete it.

I'm trying to display datetime field value in odoo website , it works using t-field and t-field-options inside span,
but i need to show as editable field in form inside input field, how to show field datetime to user timezone in input value.
you can use JavaScript
<field id="user_date" name="date" />
<script>
document.getElementById("user_date").innerHTML = Date();
</script>
I have a kendo date picker defined as follows:
<input id="datePicker" data-format="dd.MM.yyyy" data-month='{ "content": "<span class=\"#= dateRange.hasReport(data.date) ? \"boldDate\" : \"normalDate\" #\">#=data.value #</span>" }' data-role="datepicker" data-bind="value: new Date(), events: {change: dateChanged}" style="width:150px;" />
In the month template, I bold some dates depending on whether there is a report or not for that date by a call to the method dateRange.hasReport(data.date)
Now, there is an external event which causes the daterange to change. I want to now refresh the calender view so that the dateRange.hasReport is called for all dates again.
I am unable to find a way to do this.
Any ideas?
Use the methods min(), max() to change your ranges and the 'change' event will be triggered I guess. You can bind your function there if you want.
http://docs.kendoui.com/api/web/datepicker
I fixed it by destroying the element and recreating it again
$("#datePicker").data("kendoDatePicker").destroy();
$('#datePicker').empty();
createDatePicker(); //Creates the datepicker widget again
$("#datePicker").closest("span.k-datepicker").width(150);
What I want to do is automatically add an image span after my input textboxes if the [Required] attribute decorates my ViewModel property be it an integer, double, string, date etc
For example, my ViewModel might look like
public class MyViewModel
{
[Required]
public string Name { get; set; }
}
and my View would look like
#Html.EditorFor(model => model.Name)
#Html.ValidationMessageFor(model => model.Name)
and the output would be something like
<input id="Name" class="text-box single-line" type="text" value="" name="Name" data-val-required="The Name field is required." data-val-length-max="20" data-val-length="The field Name must be a string with a maximum length of 20." data-val="true">
<span class="field-validation-valid" data-valmsg-replace="true" data-valmsg-for="Name"></span>
-- Note the automatically added span
<span class="indicator required" style="width: 11px;"></span>
I was intending to have some css that would show the image i.e.
span.required {
background-image: url("required.png");
}
Is this possible to do or do I need to create my own Helper method to implement this type of functionality?
Yes, it's possible, but in general I wouldn't recommend it, because templates are really there to customize type rendering, and you should be able to create templates without worrying if it overrides another template.
I would instead create a custom LabelFor helper, such as the one described here:
http://weblogs.asp.net/imranbaloch/archive/2010/07/03/asp-net-mvc-labelfor-helper-with-htmlattributes.aspx
or here:

A third option is to not do anything in MVC, but rather add some javascript that will add the indicator based on the standard MVC validation data attributes (if you're using unobtrusive validation). See the answer here:
https://stackoverflow.com/a/8524547/61164
What I did was to modify the jquery.validate.unobtrusive JS file to add a second container, specifically for your images, if there is a validation error.
var container2 = $(this).find("[data-valimg-for='" + escapeAttributeValue(inputElement[0].name) + "']"),
replace = $.parseJSON(container.attr("data-valimg-replace")) !== false;
container2.removeClass("img-validation-valid").addClass("img-validation-error");
Then don't forget to bind it to the model:
error.data("unobtrusiveContainer", container2);
Finally, empty it in the if (replace) code block:
if (replace) {
container.empty();
container2.empty();
error.removeClass("input-validation-error").appendTo(container);
}
else {
error.hide();
}
On success, remember to hide it:
var container2 = error.data("unobtrusiveContainer"),
replace = $.parseJSON(container.attr("data-valimg-replace"));
if (container2) {
container2.addClass("img-validation-valid").removeClass("img-validation-error");
error.removeData("unobtrusiveContainer");
if (replace) {
container2.empty();
}
}
If you take a look at the onError and onSuccess functions in the file, you should be able to find out where you can put them in.
In your view, add the following line of code to each form input there's validation for:
<img class="img-validation-valid" data-valimg-replace="true" data-valimg-for="<replace with field name here, ie. Name>" src="required.png" />
I've only tested this with the [Required] attribute, but it works. I'm also pretty sure you can use this for generating other stuff as well, not just images.
I have got a hidden field with a validation for it as below
#Html.HiddenFor(m => m.Rating)
#Html.ValidationMessageFor(m => m.Rating)
The Rating property has Range validator attribute applied with range being 1-5. This is put inside a form with a submit button.
I have then got following jquery that sets the value in hidden field on some user event (Basically user clicks on some stars to rate)
$(".star").click(function(){
$("#Rating").val(2);
});
Now if I submit the form without the user event that sets the hidden field, the validation works. The error messages is displayed properly and it works all client side.
Now, in this situation, if I click on stars, that invokes the above javascript a sets the hidden field, the validation error message would not go away. I can submit the form after the hidden variable has some valid value. But I'm expecting that the client side validation should work. (When the hidden variable has been set with some valid value, the validation error should go away)
Initially I thought, the jquery validation would be invoked on some special events so I tried raising click, change, keyup, blur and focusout events myself as below
$(".star").click(function(){
$("#Rating").val(2);
$("#Rating").change();
});
But this is still not working. The error messages once appeared, does not go away at all.
You can wrap your hidden field with a div put somewhere but still inside the <form>. Add css to kick it to outer space.
<div style="position:absolute; top:-9999px; left:-9999px">
<input id="Rating" type="hidden" name="rating" >
</div>
Then add the following label to where you want to show the error:
<label for="rating" class="error" style="display:none">I am an an error message, please modify me.</label>
Client-side validation ignores hidden fields. You can set the "ignore" option dynamically but just to get it to work I did the following directlyl in the .js file.
For now this should do the trick.
In my aspx...
<%: Html.HiddenFor(model => model.age, new { #class="formValidator" }) %>
In jquery.validate.js
ignore: ":hidden:not('.formValidator')",
This turned out to be a very interesting issue. the default "ignore" setting is ignores hidden fields. The field was hidden in a jQuery ui plug-in. I simply added a class called "includeCheckBox" to the rendered input I wanted to validate and put the following line of code in...
var validator = $('#formMyPita').validate();
validator.settings.ignore = ':hidden:not(".includeCheckBox")';
if ($('#formMyPita').valid()) {....
In the code which sets the hidden field's value, manually invoke validation for the form, like so:
$("form").validate().form();
I think it is because hidden inputs don't fire any of these events.
What you could do instead would be to use a <input type="text" style="display:none" /> instead of the hidden field;
#html.TextBoxFor(m => m.Rating, new {display = "display:none"})
I have an controller which has check like that
if (form["submit"].ToString() == "Continue")
{
}
and i have button which is doing submit
<button name="submit" value="Continue">Continue</button>
It was all working well until i decided to disable Continue button on submit to prevent double click using this function:
$('form').submit(function () {
if ($(this).valid()) {
$(':submit', this).attr('disabled', 'disabled');
}
});
So now i don't get value form["submit"] posted on controller.
Any thoughts how may i fix that?
I want still prevent second click but be able to get form["submit"] value posted on controller.
Can you control the submit value in a hidden field in the form? I can't tell what other logic you might need, but when the form renders, you could set the hidden field's value to the submit button's value and change it when necessary using the first script below. As long as it has a name attribute and is enabled (which you'd rarely disable a hidden field) then it will post when the form is submitted.
$(function() {
// this assumes your button has id="myButton" attribute
$(':hidden[name="submit"]').val($('#myButton').val());
});
And of course in your form, you would need a hidden field with name="submit"
<input type="hidden" name="submit" value="Continue" />
Then, whenever the state of your form changes, modify the disabled state of the button and the value of the hidden field to reflect the value (if it changed at all).
There are also frameworks you may find useful for UI features like this. KnockoutJS comes to mind. It can be used to "value" bind input elements. It's probably overkill for this small example, but it could be useful if your UI expands. I've added markup, script and comments below if you're interested.
$(function () {
var viewModel = {
submitValue: ko.observable("Continue")
};
ko.applyBindings(viewModel);
$('form').submit(function() {
if($(this).valid()) {
// the following line will change the both the hidden field's value
// as well as the button's value attribute
viewModel.submitValue("some other value");
// I couldn't follow your selector here, but please note I changed
// the name of the submit button in the markup below.
$(':submit, this).attr('disabled', 'disabled');
}
});
});
KnockoutJS requires you use the data-bind attribute to setup your elements. In your case, you'd bind one property to multiple elements like this:
<button name="submitButton" data-bind="value: submitValue"/>Continue</button>
<!-- and bind the same value similarly in the hidden field-->
<input type="hidden" name="submit" data-bind="value: submitValue"/>
