Required Field Validation error not displaying for fields added into Array

I am trying to add the fields in the form through Observable Array in the KnockoutJS to repeat the same section of fields. But the issue is the Required Field Validation errors are not displaying for the fields that are added through the Observable Array.
Below is what I am trying
var orfViewModel = function () {
var self = this;
self.currentPage = ko.observable(1);
self.referringPage = ko.observable();
self.StrainDetails = ko.observableArray();
self.koArrayErrors = ko.validation.group(self.StrainDetails(), {
deep: true,
live: true });
self.addStrain = function () {
self.StrainDetails.push(new StrainVM());
}
self.remove = function (item) {
self.StrainDetails.remove(item);
};
I added the self.koArrayErrors validation errors within the array. So when a next button on page is clicked I am expecting to see the field required error message on the required fields.
Below is the next button logic
self.next = function () {
self.errors = ko.validation.group(this);
console.log(self.errors().length);
if (self.errors().length != 0) {
self.errors.showAllMessages();
self.koArrayErrors.showAllMessages();
}
if (!formIsValid('Page_' + self.currentPage())) {
$(window).scrollTop(0);
return false;
}
if (self.referringPage() != null) {
self.currentPage(self.referringPage());
self.referringPage(null);
} else {
self.currentPage(self.currentPage() + 1);
}
self.gotoPage();
};
self.gotoPage = function () {
$("div[id^='Page_']").hide();
$("div[id^='Page_" + this.currentPage() + "']").show();
$(window).scrollTop(0);
self.errors.showAllMessages(false);
self.koArrayErrors.showAllMessages(false);
};
Below is the StrainVM() which pushes the data in to the Observable array like
function StrainVM() { var self = this;
self.pdtNeeded = ko.observable().extend({ required: { params: true, message: "Required! Please sect Pdt Needed" } });
ko.validation.registerExtenders();
Even though I don't enter anything for pdtNeeded field, clicking on the Next button does not take me to next page and does not show the error Required! Please sect Pdt Needed next to field.
Users will not know what is not letting them to hit the next page.
How can I handle the validation here that is added to Observable array?

How to run 2 js functions

I have 2 function that I am trying to run, one after another. For some reason they both run at the same time, but the second one does not load properly. Is there a way to run the first function wait then run the second function?:
//run this first
$('#abc').click(function() {
$('.test1').show();
return false;
});
//run this second
(function ($) {
"use strict";
// A nice closure for our definitions

How would I run the first one wait 5 or so seconds and then run the jquery print? I'm having a hard time with this. So the id would run first and then the print would run adter the id="abc" Here is an example of the code in use:
<div id="test">
<button id="abc" class="btn" onclick="jQuery.print(#test1)"></button>
</div>

If I understand your problem correctly, you want the jQuery click function to be run first, making a div with id="test1" visible and then, once it's visible, you want to run the onclick code which calls jQuery.print.
The very first thing I will suggest is that you don't have two different places where you are handling the click implementation, that can make your code hard to follow.
I would replace your $('#abc').click with the following:
function printDiv(selector) {
$(selector).show();
window.setTimeout(function () {
jQuery.print(selector);
}, 1);
}
This function, when called, will call jQuery.show on the passed selector, wait 1ms and then call jQuery.print. If you need the timeout to be longer, just change the 1 to whatever you need. To use the function, update your example html to the following:
<div id="test">
<button id="abc" class="btn" onclick="printDiv('#test1')"</button>
</div>
When the button is clicked, it will now call the previously mentioned function and pass it the ID of the object that you want to print.
As far as your second function goes, where you have the comment **//run this second**, you should leave that alone. All it does is extend you jQuery object with the print functionality. You need it to run straight away and it currently does.

How do I capture if the enter key has been pressed?

I'm trying to capture if the enter key has been pressed and execute a search. This is the viewmodel for the search page.
(function ()
{
a.viewModels.userSearch = function (view, params) {
$view = $(view);
var self = a.viewModel({
users: a.collection({
url: '/admin/Account/SearchUsers',
query: {
SearchText: null
}
}).fetch(),
setPageIndex: setPageIndex,
search: search
});
$view.keypress(function (e) {
if (e.keyCode == 13) {
self.search(e);
}
});
function search(e) {
self.users.query.rowCount = 0;
self.users.query.pageIndex = 1;
self.users.fetch();
}
function setPageIndex(e) {
e.preventDefault();
self.users.query.set('pageIndex', $(e.currentTarget).data('page-index'));
self.users.fetch();
}
return self;
}
Now, this works. The problem is that it works only after pressing the 'Enter' key 2 times. Seems like I'm missing something related to the scope but js ain't my cup of tea.
If it is of any help, here goes my view model function:
function viewModel(viewModelConfig) {
var self = kendo.observable($.extend({
busy: 0,
resultMessage: null,
clearResultMessage: clearResultMessage
}, viewModelConfig));
self.bind('change', onChange);
function onChange(change) {
var errorProp, errorMsg, infoProp, infoMsg;
if (change.field.endsWith('.busy')) {
if (self.get(change.field))
self.set('busy', self.busy + 1);
else if (self.busy > 0)
self.set('busy', self.busy - 1);
}
else if (change.field.endsWith('.resultMessage')) {
var data = self.get(change.field);
self.set('resultMessage', data);
}
}
function clearResultMessage(e)
{
if (e) e.preventDefault();
self.set('resultMessage', null);
return false;
}
return self;
}

I have a similar setup on my site, and using MVVM, just add the custom enter binding within the data-bind attribute of the element to link to the function within the view-model you wish to execute.
The code to add the custom binder is as such:
kendo.data.binders.widget.enter = kendo.data.Binder.extend({
init: function(element, bindings, options) {
kendo.data.Binder.fn.init.call(this, element, bindings, options);
var binding = this.bindings.enter;
$(element.element).keyup(function(e) {
if( e.which === 13 )
bindings.get();
});
},
refresh: $.noop
});

Transforming old code to ember component

currently i'm starting with Ember, and i'm loving it! I'm with some difficulties, especially when it comes to components.
For you to understand, I'm going through old code to Ember, and I would like to turn this code into a Component, but I do not know actually how to start, since I do not know how to catch the button being clicked, and I also realized that Ember has several helpers, maybe I do not need any of this giant code to do what I want.
This is the old code result: http://codepen.io/anon/pen/WQjobV?editors=110
var eventObj = {};
var eventInstances = {};
var actual;
var others;
var clicked;
var createEventInstance = function (obj) {
for (var key in obj) {
eventInstances[key] = new Event(obj[key]);
}
};
var returnStyle = function (inCommon) {
var $inCommon = inCommon;
$inCommon.css({
width: '342.4px',
minWidth: '342.4px'
});
$inCommon.find('.cta').removeClass('hidden');
$inCommon.find('.event-close').removeClass('inline');
$inCommon.find('.event-info_list').removeClass('inline');
$inCommon.removeClass('hidden');
$inCommon.find('.expanded').slideUp();
$inCommon.find('.expanded').slideUp();
$inCommon.find('.event-arrow').remove();
$inCommon.find('h2').find('ul').remove('ul');
};
var Event = function (id) {
this.id = id;
};
Event.prototype.expandForm = function () {
actual.css('width', '100%');
actual.find('.event-info_list').addClass('inline');
actual.find('.expanded').slideDown().css('display', 'block');
actual.find('.event-close').addClass('inline');

Basically i have this boxes, which box represent one booking in some event (will be populate by the server). When the user clicks in one box, this boxes expands and the other disappear. But than a dropbox will be created with the other boxes, so the user can navigate in the events by this dropdown.
I didn't do much with Ember, i transform the "events" div into a component with the name "BookingBoxComponent" and two actions:
SiteApp.BookingBoxComponent = Ember.Component.extend({
actions:
open: function() {
// HOW COULD I ACCESS THE CLICKED BUTTON HERE?
},
close: function() {
}
});
As you can see, i put two actions, one for opening the box and other for closing, should i just put the logic in both, or i can improve this like a Ember way?
I don't know if i am asking to much here, so if i am, at least i would like to know how to access the button clicked in the open method, i was trying passing as a parameter, like:
<button {{action 'open' this}}></button>
But didn't work.
I could offer 50 of my points to someone who help transform the old cold in a Ember way code.
Thanks.

The event object will be passed with every action as the last parameter, so when you specified this you were actually passing whatever object has context in that block. In your open function, do not pass this and do
open: function(event) {
// event.currentTarget would be the button
}
And now you can do something like event.currentTarget or event.target

jquery draggable revert programmatically

I am currently developing a calendar where activities can be drag&dropped to other days.
When an activity is dropped into a different day, I show a custom modal using durandal's dialog plugin. The problem is when an user closes the modal, the activity has to revert to its original position. When an activity is dropped the following code is called:
function showDroppedActivityModal(obj) {
require(['modals/droppedActivityModal/droppedActivityModal', 'moment'], function(droppedActivityModal, moment) {
droppedActivityModal.show(obj).then(function(response) {
if(response !== false) {
...
}
// dialog closes
else {
calendarView.revertActivity.notify({ revert: true})
}
});
});
}
In my calendarView I implemented the revertActivity event to set revert to true but the function never re-evaluates itself but i'm able to receive the new revert value (true).
$(activity).draggable({
revert: function() {
var revert = false;
self.revertActivity.attach(function(sender, args) {
revert = args.revert;
});
return revert;
}
});
Custom event code:
function CalendarEvent(sender) {
this._sender = sender;
this._listeners = [];
}
CalendarEvent.prototype = {
attach : function (listener) {
this._listeners.push(listener);
},
notify : function (args) {
var index;
for (index = 0; index < this._listeners.length; index += 1) {
this._listeners[index](this._sender, args);
}
},
remove : function (listener){
this._listeners.remove(listener);
}
};
this.revertActivity = new CalendarEvent(this);
