I am using Jhipster V3.
I have created an entity, and Jhipster generated all the needed views.
My client wants that in the update dialog of this entity, the click on Save doesn't close the popup.
I have commented one line on this function :
var onSaveSuccess = function (result) {
$scope.$emit('rhTechvalleyApp:consultantUpdate', result);
//$uibModalInstance.close(result);
vm.isSaving = false;
};
In this popup I have a datepicker component. Its value is getting blank once the save process has finished. It s only a display issue, but I don't know how to get rid of it.
If anyone knows...
Thanks.
[UPDATE]
transformResponse: function (data) {
data = angular.fromJson(data);
data.dateEnregistrement = DateUtils.convertLocalDateFromServer(data.dateEnregistrement);
data.dateDernierPointDisponibilite = DateUtils.convertLocalDateFromServer(data.dateDernierPointDisponibilite);
data.dateDisponibilite = DateUtils.convertLocalDateFromServer(data.dateDisponibilite);
return data;
}
<div class="input-group">
<input id="field_dateEnregistrement" type="text" class="form-control" name="dateEnregistrement" uib-datepicker-popup="{{dateformat}}" ng-model="vm.consultant.dateEnregistrement" is-open="vm.datePickerOpenStatus.dateEnregistrement"/>
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="vm.openCalendar('dateEnregistrement')"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</div>
You need to add transformResponse to the update function of the Angular service for your entity. It should be the same as transformResponse for get.
Example:
'update': {
method:'PUT',
transformResponse: function (data) {
data = angular.fromJson(data);
data.birthDate = DateUtils.convertLocalDateFromServer(data.birthDate);
return data;
}
}
The reason you need to do this is because the server will return a string like 2016-04-12 for dates. This needs to be converted to a JavaScript Date object, which is what Angular expects for type="date" inputs. If you use a string instead of a date object for ngModel on a date input, Angular will throw an error and fail to fill the field. You can use DateUtils.convertLocalDateFromServer for LocalDate and DateUtils.convertDateTimeFromServer for DateTime.

"I am creating TODO list using Node as backend. after adding every new item, a checkbox is also generating in front of them so I can apply "CSS line-through" to let user know that item is done or of no use. But when I add another item, the page refreshes and that checkbox is unchecked as I am not storing that value anywhere. Can you tell me how to store the value of that checkbox in the backend?
HTML -
<div class="box" >
<% for (var i=0; i<newListItems.length; i++) { %>
<div class="item">
<input type="checkbox" id="checkBox">
<p> <%= newListItems[i] %> </p>
</div>
<% } %>
<form action="/" method="post" class="item">
<input class="inputBox" type="text" name="newItem" placeholder="New item" autocomplete="off" required="required">
<button type="submit" name="list" value=<%= listTitle%>> +</button>
</form>
</div>
Node JS -
const items = [];
app.post("/", function(req, res){
let item = req.body.newItem;
items.push(item);
res.redirect("/");
});
The answer involves a lot of code, so I will give you a set of steps that can help in your case.
You need to change your data scheme. Currently looks like you are just storing the string in an array of items. You need to change it to be array of objects. Each object should have the field task and done. So you could know which task is done or not.
app.post("/", function(req, res) {
let item = req.body.newItem;
items.push({ name: item, done: false });
res.redirect("/");
});
Next step will be adding an endpoint that will be changing the done field of an array item to true.
Then on a front-end you will need to write some JS code that will be sending an HTTP request to the endpoint that marks the task as done. You need to use AJAX call for that, for example, NPM package axios.
Change the template to reflect the changes to the data. e.g. instead of <%= newListItems[i] %> do <%= newListItems[i].name %> and add logic to render checked checkbox based on done property.
It worth to mention, that you should not store data in memory, because once the process is done, you will lose your data. It is okay for learning purposes, but in production, you should use a database.
I am using angular to create a booking web app using firebase. I am trying to query through the firebase data and filter them to avoid duplicate bookings to be recorded at the same time slots, but I keep getting the error Function Query.where() called with invalid data. Unsupported field value: undefined. I am new to angular and firebase and this is my first project as well. I could really use some help on this.
checkTimeSlot(){
this.formData.date_time = this.formData.bookDate + "_"+ this.formData.timeSlot;
const queryTimeRefUFC = this.afs
.collection("ufc", ref => ref.where("date_time", "==", this.formData.date_time))
.get();
if (queryTimeRefUFC == null){
console.log("true");
return true;
}
else{
console.log("false");
return false;
}}
This is the method in the component.ts where I created the query search. This method is called when the value in the select input changes.
submitBookingUFC() {
this.formData.fullName = this.user.name;
this.formData.userID = this.user.id;
this.formData.date_time = this.formData.bookDate + "_"+ this.formData.timeSlot;
if (this.checkTimeSlot() == true){
alert("The Time Slot you have selected has already been taken. Please select another.");
}
else if (this.checkTimeSlot() == false){
console.log(this.formData.date_time);
this.crudApi.SaveBookingUFC(this.formData);
alert("Record Saved Successfully");
this.ResetFormUFC(); // Reset form when clicked on reset button
} }
This is the method called when the user clicks the submit button.
<div>
<input
type="date"
class="in-bdate"
id="dateUFC"
name="dateUFC"
[min]="today"
max="{{bookMax}}"
value="{{formData.bookDate}}"
[(ngModel)]="formData.bookDate"
#dateUFC="ngModel"
required>
</div>
<div>
<div style="color:red"
*ngIf="dateUFC.errors && (dateUFC.dirty || dateUFC.touched)">
<p *ngIf="dateUFC.errors.required">
<sup>*</sup>Booking Date is required
</p>
</div>
</div>
<div *ngIf="!dateUFC.errors && (dateUFC.dirty || dateUFC.touched)">
<div>
<label for="timesUFC">Time Slot</label>
</div>
<div>
<select
name="timesUFC"
class="in-tslot"
value="{{formData.timeSlot}}"
(change)="checkTimeSlot()"
[(ngModel)]="formData.timeSlot"
#timeSlotUFC="ngModel"

<option *ngFor="let time of timesUFC" >{{time.name}}</option>
</select>
</div>
<div>
<div style="color:red"
*ngIf="(timeSlotUFC.dirty || timeSlotUFC.touched)">
<p *ngIf="timeSlotUFC.errors && timeSlotUFC.errors.required">
<sup>*</sup>Time Slot is required
</p>
<p [ngModel]="timeError" name="error" ngDefaultControl>{{ timeError }}</p>
</div>
</div>
</div>
This is the html code I used to attain the date for the booking and the time of the booking. Using these I created a composite field as date_time using this.formData.date_time = this.formData.bookDate + "_"+ this.formData.timeSlot; to avoid getting duplicate bookings for the same time slot on the same day. The formData here is linked to a class I created for the entire booking array using formData = new UfcData; where UfcData is the name of the class.
export class UfcData {
docID!: string;
userID!: string;
fullName!: string;
contactNo!: string;
timeSlot!: string;
bookDate!: string;
date_time!: string;}
This is the data in the UfcData class.
This is how my Collection and Documents look like
What I need is to acquire the user's input from the form which is acquire from ngModel to the UfcData class and make sure that there aren't any documents in the cloud firestore with the exact same date and time.
*After tweaking the code a little bit the above error does not display. However the if condition in the checkTimeSlot() method always returns true no matter what the option on the select is.
Thanks in advance.
This may be a basic question, but I'm struggling. Essentially I have a livewire component that updates an array of flight information that a user enters. Whenever the components get rerendered, the flatpickr functionality stops working entirely. I presume this is because the javascript to initialize the component on that field is not running. What is the best practice to ensure these get rerendered with the appropriate javascript to enable the functionality.
Here's my blade snippet which renders fine on the initial load, but whenever a change to the data occurs, the page re-renders all the flights in the array, but the flatpickr functionality does not work anymore.
<form>
#foreach($flights as $i => $f)
<label
x-data
x-init="flatpickr($refs.input, {
dateFormat: 'Y-m-d H:i',
altInput: true,
altFormat: 'F j, Y h:i K',
enableTime: true,
})">
<div class="form-label">Arrival Time</div>
<div class="relative">
<input type="text"
wire:model="flights.{{ $i }}.ArrivalTime"
wire:key="fl{{ $i }}arrtime"
data-input
x-ref="input"
placeholder="Arrival Time"
value="{{ $f['ArrivalTime']}}"
name="flights[{{ $i }}][ArrivalTime]"
id="ArrivalTime{{$i}}"
/>
</div>
</label>
#endforeach
</form>
The livewire component is basically this:
class Itinerary extends Component
{
public $itin = null;
public $flights = [];
public function render()
{
return view('livewire.itinerary');
}
}
You need to wrap the input in a <div> like this:
<div wire:ignore>
<!-- Your input here -->
</div>

I am working on a small project with checkbox and node js. I need the checked box stay on the screen after I click submit button and reset the form after clicking reset button.How can do that?
ejs code
<form method="post" action="/">
<input type="checkbox" name="preference" value="A">A
<input type="checkbox" name="preference" value="B">B
<input type="checkbox" name="preference" value="C">C
<input type="submit" value="Click to Submit">
<input type="reset" value="Erase and Restart">
</form>
node js
express.get('/', (req, res) => {
res.render('form');
});
express.post('/', (req, res) => {
console.log(req.body);
let checkedValue =req.body.preference;
let output = checkedValue==undefined?`You didn' make selection.`:`The preference iterm on menu is ${checkedValue}`;
res.render('form',{
output:output,
});
});
What's going on is that when you submit your form, the webpage is reloaded, so you lose your checked state. You can either save the values on your server and have them pre-checked using an optional checked flag in your ejs template or you can add some client side javascript to handle the form submission for you by writing and event handler for the submit event on the form.
if you expand your ejs template with a conditional checked value on your inputs, your returned page will have them pre-checked
<input type="checkbox" name="preference" <% if (submittedValue === "A") { %>checked<% } %> value="A">A
Or, here's a super simple bit of javascript that would send the values to your server
document.forms[0].addEventListener('submit', function (e) {
e.preventDefault(); // prevent the form from submitting with a page refresh
const data = { values: [] };
e.target.elements.forEach((formEl) => {
if (formEl.checked) data.values.push(formEl.value);
});
fetch('/urlToProcessYourForm', { method: 'POST', body: JSON.stringify(data) });
});
I have a job application form as part of a site built on ServiceStack. I am attempting to use the included ss-utils.js to leverage built-in Fluent Validation, but my form doesn't post the user's file upload. Here's the relevant snippet of the form:
<form id="form-careerapplication" action="#(new CreateCareerApplication().ToPostUrl())" method="post">
<div class="error-summary"></div>
<div class="form-group">
<label>
Upload Resume
</label>
<input type="file" id="Resume" name="Resume" />
<span class="help-block"></span>
</div>
<input type="hidden" name="Id" value="#Model.Id" />
<input type="submit" value="Submit Application" />
</form>
<div id="success" class="hidden">
Thank you for your application.
</div>
$("#form-careerapplication").bindForm({
success: function (careerApplicationResponse) {
$("#form-careerapplication").addClass("hidden");
$("#success").removeClass("hidden");
},
...
Is there something I'm missing in ss-utils.js? Or is there a way of overriding / supplementing the submit behavior to use FormData?
Uploading files via a HTML FORM requires a enctype="multipart/form-data", e.g:
<form id="form-careerapplication" action="#(new CreateCareerApplication().ToPostUrl())"
method="post" enctype="multipart/form-data">
...
</form>
If you want to change support multiple file uploads or change the appearance of the UI Form I recommend the Fine Uploader, there's an example showing how to use Fine Uploader on the HTTP Benchmarks Example.
Whilst Imgur has a simple client HTML and Server example.
Turned out I can use the beforeSend option as part of the configuration passed into bindForm to override the data being sent. Its a bit of a hack, but it worked and I keep the original ss-utils.js fluent validation!
$("#form-careerapplication").bindForm({
success: function (careerApplicationResponse) {
....
},
error: function (error) {
....
},
contentType: false,
processData: false,
beforeSend: function (x, settings) {
var fd = new FormData();
// Tweaked library from https://github.com/kflorence/jquery-deserialize/blob/master/src/jquery.deserialize.js
// Used to translate the serialized form data back into
// key-value pairs acceptable by `FormData`
var data = $.fn.deserialize(settings.data);
$.each(data, function (i, item) {
fd.append(item.name, item.value);
});
var files = $('#form-careerapplication').find("input:file");
$.each(files, function (i, file) {
fd.append('file', file.files[0], file.files[0].name);
});
settings.data = fd;
}
});
