Conditionally tick the checkbox in modal dialog in Angular - javascript

I have a bootstrap modal dialog which contains some checkboxes. Each checkbox represents a category from the database and I need to tick the checkbox only if the user is interested on that category.
following is my html for the modal
<div *ngIf="_user" id="categoryModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-body" id="categoryDiv">
<div class="row">
<div *ngIf="_tenderCategories">
<span *ngFor="let category of _tenderCategories; let i = index;">
<div class="col-md-4">
<div class="checkbox">
<label>
<input id={{category.id}} type="checkbox" class="category-checkbox" [checked]="isUserInterested(category)" (change)="onCategoryCheckBoxClick(category)">
<p class="tender-category" style="cursor: pointer;">{{category.name}}</p>
</label>
</div>
</div>
</span>
</div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Submit</button>
</div>
</div>
</div>
</div>
As you can see, in order to tick the checkbox, I call the function isUserInterested(category).
The problem I face is, when the page reloads only, the function I mentioned gets called. The modal above appears when I click a link on my html page; but the function does not get called in that case. By the time I click the above mentioned link, the component has all the data required for the function to execute.
isUserInterested(category: Category) {
if (this._user.interestedCategories.indexOf(category) > -1) {
// if the _user.interestedCategories list contaians the category, that category should be shown as marked
console.log("Category "+category.id+" interested");
return true;
} else {
return false;
}
}
Why I am not getting the expected behavior? How can I get this implemented in the way I expect?

You should be using ngModel to achieve this as below,
<input id={{category.id}} type="checkbox" class="category-checkbox"
[ngModel]="isUserInterested(category)"
(ngModelChange)="onCategoryCheckBoxClick(category)">
Update 1 : Inside Modal dialog
The child model should contain the users object as below,
#Input() users?:any[];
Method will be as
isUserInterested(c){
if(this.category.interestedCat.indexOf(c) > -1){
console.log(c)
return true;
}
else {
return false
}
}

How to edit passed data from parent to child component in Angular 4

I have parent component with all teams and child component for displaying each of team in box using *ngFor and #Input. All child components are displayed fine but when I want to change each of them opening modal I always get the data from first object in array of teams.
team.component.html
<app-team-box *ngFor="let team of teams" [team]="team"></app-team-box>
team-box.component.html
<div class="ibox">
<div class="ibox-title">
<h5>{{this.team.name}}</h5>
<a class="btn btn-xs" (click)="openEditTeamModal(this.team)">Edit</a>
</div>
</div>
<div class="modal fade" id="edit_team_modal">
<div class="modal-dialog">
<div class="modal-content">
<form role="form" (ngSubmit)="editTeam()" novalidate>
<div class="modal-body">
<div class="row" *ngIf="this.team">
<label>Team name:</label>
<input type="text" id="name" name="name" [(ngModel)]="this.team.name" #name="ngModel">
</div>
</div>
<div class="modal-footer">
<button type="submit">Save</button>
</div>
</form>
</div>
</div>
team-box.component.ts
export class TeamBoxComponent implements OnInit {
#Input() team;
constructor(private teamService: TeamService) {}
openEditTeamModal(selectedTeam): void {
this.team = selectedTeam;
$("#edit_team_modal").modal();
$(".modal").appendTo("html");
}
editTeam(): void {
this.teamService.update(this.team).subscribe((team: Response) => {
$("#edit_team_modal").modal("hide");
});
}
}
The problem is when I change first one everything is fine, modal is populated with name and after changing it's get saved. But when I click on edit button for example second team, in modal I get the data for first team. Why this.team is always referencing to first object in array of teams?

Converting Bootstrap 3 remote modal to Bootstrap 4 modal with parameters

So in the near future my shop is going to upgrade to Bootstrap 4 but we cannot do this until we solve the issue with using remote modals. Here is an example of how we load our modals. The reason we use remote modals is because the modal-body is dynamic and may use different file based on the url. I have heard that using jQuery("#newsModal").on("load",..) is an alternative but how could I do this? I found this but I am not sure how my anchor would look and how to build the url to load the remote data.
Global PHP include file:
<div id="NewsModal" class="modal fade" tabindex="-1" role="dialog" data-
ajaxload="true" aria-labelledby="newsLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 class="newsLabel"></h3>
</div>
<div class="noscroll-modal-body">
<div class="loading">
<span class="caption">Loading...</span>
<img src="/images/loading.gif" alt="loading">
</div>
</div>
<div class="modal-footer caption">
<button class="btn btn-right default modal-close" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
modal_news.php file:
<form id="newsForm">
<div id="hth_err_msg" class="alert alert-danger display-hide col-lg-12 col-md-12 col-sm-12 col-xs-12">
You have some errors. Please check below.
</div>
<div id="hth_ok_msg" class="alert alert-success display-hide col-lg-12 col-md-12 col-sm-12 col-xs-12">
✔ Ready
</div>
<!-- details //-->
</form>
Here is how we trigger the modals :
<a href="#newsModal" id="modal_sbmt" data-toggle="modal" data-target="#newsModal"
onclick="remote='modal_news.php?USER=yardpenalty&PKEY=54&FUNCTION=*GENERAL'; remote_target='#NewsModal .noscroll-modal-body'">
<span class="label label-icon label-info">
<i class="fa fa-bullhorn"></i>
</span>
Promotional Ordering
</a>
I think I need to do something like this when building anchor dynamically:
a) Replace paramters with data-attrs
b) Use the event invoker to get the data-attrs using event.target.id
Thanks to Tieson T. and this post I was able to effectively pass parameters to the remote modal using this technique except if you have multiple modals
I have also included some helpful techniques inside this example as to how you may pass parameters to the remote modal.

$(".add-attendee").addClass("hidden");
$("#signupForm input[type='hidden']").remove();
});

<script>
$(document).ready(function(){
console.log('<?php echo $_GET["USERNAME"]?>'); //passed through url
});
</script>
NOTE: I am having problems with event propagation during the show.bs.modal event which I have a global show.bs.modal that is propagating up to this event handler due to multiple modals so if you have multiple modals make sure to handle them correctly.
Here is a screen shot of the results which clearly show propagation is taking place but the parameter passing techniques are working.
You might find it easier to use something like Bootbox.js, which can be used to dynamically create Bootstrap modals.
Given what you've shown, it would work something like:
trigger modal
with
$(function(){
$('.show-modal').on('click', function(e){
e.preventDefault();
var url = $(this).attr('href');
$.get(url)
.done(function(response, status, jqxhr) {
bootbox.dialog({
title: 'Your Title Here',
message: response
});
});
});
});
This assumes response is an HTML fragment.
Bootbox hasn't officially been confirmed to work with Bootstrap 4, but I haven't run into any problems with it yet (modals seem to be one of the few components that don't have updated markup in BS4).
Disclaimer: I am currently a contributor to Bootbox (mainly updating the documentation and triaging issues).
If you must use only the Bootstrap modal, you're actually after load(). You would probably do something like:
$(function(){
$('.show-modal').on('click', function(e){
e.preventDefault();
var url = $(this).attr('href');
var dialog = $('#NewsModal').clone();
dialog.load(url, function(){
dialog.modal('show');
});
});
});

Javascript waiting result of modal

I have a simple question about javascript and bootstrap modal. I have a wizard where I use file upload form, so I check the name of the file and if it doesn't contains some string I have to show a modal where ask if you want to continue anyway. How can I know which button is clicked into modal from javascript or jquery?
I have this code:
if (index==3){
var fileControl = document.getElementById('file');
//Check if the datatable name contains idFLeet and IdCar. REturn -1 if it not contains the string
if (fileControl.files[0].name.indexOf($("#selectedFleet").val()) > -1 && fileControl.files[0].name.indexOf($("#selectedCar").val()) > -1){
//File contains id so you can continue the upload
uploadFunction();
}
else{
$('#warningDatatableModal').modal("show");
//If click on Yes call uploadFunction
//If click on No return false
}
}
HTML modal code:
<div class="modal" id="warningDatatableModal" data-backdrop="static" data-keyboard="false">
<div class="modal modal-warning">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title">Warning</h4>
</div>
<div class="modal-body">
<p>There is a incongruity between file name and fleet and
car previously selected. Are you sure to continue?</p>
</div>
<div class="modal-footer">
<button id="close" type="button" class="btn btn-outline pull-left"
data-dismiss="modal">Close</button>
<button id="continueButton" type="button" class="btn btn-outline">Continue</button>
</div>
</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->
</div>
</div>
After Yeldar Kurmangaliyev advice I have update my code but the wizard go ahed to the next tab instead of waiting into actual tab
if (index==3){
var fileControl = document.getElementById('file');
//Check if the datatable name contains idFLeet and IdCar. REturn -1 if it not contains the string
if (fileControl.files[0].name.indexOf($("#selectedFleet").val()) > -1 && fileControl.files[0].name.indexOf($("#selectedCar").val()) > -1){
//File contains id so you can continue the upload
uploadFunction();
}
else{
$('#warningDatatableModal').modal("show");
$(".modal-footer > button").click(function() {
clicked = $(this).text();
$("#warningDatatableModal").modal('hide');
});
$("#warningDatatableModal").on('hide.bs.modal', function() {
if (clicked === "Cancel"){
return false;
}else {
uploadFunction();
}
});
}
}
If I put this code out of wizard works(it doesn't close modal with cancel button because I use return false that needs for my wizard), but I need to stop wizard waiting modal result.
You can simply attach events to your buttons.
However, the user may want to close the window without action. The design of modal UI and its overlay suggests to click outside the window and close it.
In order to create an event which will fire event always when a user closes your modal, you need to attach to hide.bs.modal event:
$('#warningDatatableModal').on('hide.bs.modal', function() {
});
Here is the working JSFiddle demo.
You can try using the ids of the buttons and attaching a listener to see when they have been clicked like so:
$('#close').on('click',function(){
//do something
});
$('#continueButton').on('click',function(){
//do something
});

how to make JS wait for confirmation modal

This might be really stupid but I am not seeing anything straight here, help me out please.
so their is this guy :
As you can see upon click the function changeBlock is called
this.changeBlock = function() {
var flag = confirm("You sure you want to block this user ?");
if(flag){
blockUser(this.postId);
if(this.block() != ""){
this.block("Blocked");
this.pointId(AS.currentUserDetails.name);
return "Blocked";}
}
}
and somewhere lie the function blockUser
function blockUser(post_id) {
var blockUser = AS.baseUrl + "blockNewUser";
$.ajax({
url:blockUser,
type:"POST",
data:{postId : post_id},
success:function(data) {
// `request` seems a very strange name; perhaps `data` or `response`?
},
error: function(){
// You can't use `document.write` after the page has been parsed
}
});
}
My problem is that I cant use confirm() for confirming block or cancel.
I will have to use a html modal which is used through out the website.
If at some point of the execution I add
$('#my-modal').modal('show');
then though the modal appears but rest of the execution takes place without waiting for me to select yes or no.
And if by some magic I manage to make JS wait for selection, How will I know what was selected ?
what should I do ?
I cannot use any third party modals.
here is the modal I want to use :
<div id="block-confirm-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-body">
<div class="clearfix side-space">
<h3 class="modal-title text-center">Are you sure you want to Block this user ?</h3>
</div>
<form id="form-block-confirm" name="" method="post" action="" class="form-horizontal">
<div class="clearfix side-space">
<div class="clearix text-center">
<button type="submit" class="btn btn-saffron btn-introduce" id='block-confirm-button'>Block</button>
<button type="submit" class="btn btn-saffron btn-introduce" id='block-cancel-button'>Cancel</button>
<!--input type="submit" name="submit" class="btn btn-saffron btn-introduce" value="Post"-->
</div>
</div>
</form>
</div>
</div>
</div>
</div>
you should be doing something like this in such situations .
In View Model:
this.changeBlock = function() {
$('#my-modal').modal('show');
}
function blockUser(post_id) {
//code here
}
this.Block=function(){
blockUser(this.postId);
if(this.block() != ""){
this.block("Blocked");
this.pointId(AS.currentUserDetails.name);
return "Blocked";}
}
}
this.Cancel=function(){
$('#my-modal').modal('hide'); //hide or close what ever suits
}
View :
<button id='block-confirm-button' data-bind="click:Blocked">Block</button>
<button id='block-cancel-button' data-bind="click:Cancel">Cancel</button>
Any issues on this lets us know

Modal Form Submission without refresh

I have a modal window that pops up when I want to add a new project to my dashboard. I have gotten it to work with jquery post however, I cannot prevent it from refreshing. What I want to do is after the project is added to the database, show a success message and close the modal window after few seconds and not refresh the page (parent page of modal).
Here is my modal
<div class="modal fade" id="add-project-dialog" tabindex="-1" role="dialog" aria-labelledby="basicModal" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
<h4 class="modal-title" id="myModalLabel">Add a new Project</h4>
</div>
<div class="modal-body">
<h3>New Project:</h3>
<form class="form-horizontal" id="add-project-form" action="/projects/add" method="POST">
<fieldset>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="name">Project Name</label>
<div class="col-md-4">
<input id="name" name="name" type="text" placeholder="" class="form-control input-md">
</div>
</div>
<!-- Text input-->
<div class="form-group">

<div class="col-md-4">

</div>
</div>
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="project_state">Project State</label>
<div class="col-md-4">
<input id="project_state" name="project_state" type="text" placeholder="" class="form-control input-md">
</div>
</div>
</fieldset>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button id="add-btn" class="btn" type="submit">Add</button>
</div>
</form>
</div>
</div>
Here is my project-dashboard.js
AddProject = function(){
$(document).ready(function() {
$("#submit").submit(function(event){
event.preventDefault();
$.ajax({
url: "/projects/add",
type:"POST",
data:
{
'name': $('#name').val(),
'description': $('#description').val(),
'project_state': $('#project_state').val()
}
});
});
});
}
My views.py
class AddProject(webapp2.RedirectHandler):
def get(self):
template_values = {
#'greetings': greetings,
#'url_linktext': url_linktext,
}
path = os.path.join(os.path.dirname(__file__), '../templates/project-add.html')
self.response.write(template.render(path, template_values))
def post(self):
project = Project()
project.name = self.request.get('name')
project.description = self.request.get('description')
project.project_state = self.request.get('project_state')
time.sleep(2)
project.put()
self.redirect('/projects')
I have tried removing the self.redirect('/projects') however that only takes me to a blank page that is /projects/add (that is the action in the form).
The issue is that you added .ready(foo) handler inside of the AddProject function. I suppose that document is loaded when AddProject is called.
Another issue is that in your HTML, the form has id add-project-form, so you should do $("#add-project-form") instead of $("#submit").
$(document).ready(function () {
$("#add-project-form").submit(function(event){
event.preventDefault();
$.ajax({
url: "/projects/add",
type:"POST",
data:
{
'name': $('#name').val(),
'description': $('#description').val(),
'project_state': $('#project_state').val()
}
});
});
});
});
Take ready handler outside of the AddProject function and it should work (the submit handler is added).
Edit: After some debugging, the answer was to use the right id and proper placing of the javascript code, as noted by the comments.
For starters, a refresh is easy to avoid, just make sure to prevent the default event from running; since you're using jQuery, I would recommend doing return false to end the function, since it both 'prevents default' and 'stops propagation'.
So the first thing you should do is check if your javascript code is actually running and not erring in the middle of execution. If everything is fine there, the worst case is that the project is not actually added (server side error) but the page should not refresh.
Your server side code has nothing to do with the refresh (if it's being properly hijacked), so the response doesn't really matter, I would actually return the id of the new project (so you could provide a link for the newly created item or something like that), but i digress...
Here is a snippet for not only closing modals without page refresh but when pressing enter it submits modal and closes without refresh
I have it set up on my site where I can have multiple modals and some modals process data on submit and some don't. What I do is create a unique ID for each modal that does processing. For example in my webpage:
HTML (modal footer):
<div class="modal-footer form-footer"><br>
<span class="caption">
<button id="PreLoadOrders" class="btn btn-md green btn-right" type="button" disabled>Add to Cart <i class="fa fa-shopping-cart"></i></button>
<button id="ClrHist" class="btn btn-md red btn-right" data-dismiss="modal" data-original-title="" title="Return to Scan Order Entry" type="cancel">Cancel <i class="fa fa-close"></i></a>
</span>
</div>
jQUERY:
$(document).ready(function(){
// Allow enter key to trigger preloadorders form
$(document).keypress(function(e) {
if(e.which == 13) {
e.preventDefault();
if($(".trigger").is(".ok")) //custom validation dont copy
$("#PreLoadOrders").trigger("click");
else
return;
}
});
});
As you can see this submit performs processing which is why I have this jQuery for this modal. Now let's say I have another modal within this webpage but no processing is performed and since one modal is open at a time I put another $(document).ready() in a global php/js script that all pages get and I give the modal's close button a class called: ".modal-close":
HTML:
<div class="modal-footer caption">
<button type="submit" class="modal-close btn default" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
jQuery (include global.inc):
$(document).ready(function(){
// Allow enter key to trigger a particular class button
$(document).keypress(function(e) {
if(e.which == 13) {
if($(".modal").is(":visible")){
$(".modal:visible").find(".modal-close").trigger('click');
}
}
});
});
Now you should get no page refreshes on any of your modals if u follow these steps.
