I am new to Angular and learning by implementing a chat application.
I am trying to pass the checkbox values to my JS code. Below are the snippets. The problem I am facing is I am unable to get the checked values in JS. I am getting i.value as undefined. Can you please point out where am i going wrong?
<div class="add-friends panel-primary panel" ng-show="addfriendsselected">
<div class="panel-heading text-center" >Add Friends</div>
<div class="panel_body">
<div class="row" id=myForm>
<ul class="list-group">
<li class="list-group-item" ng-repeat = "user in friendslist">
<div>
{{user.firstName}}
{{user.email}}
<input type="checkbox" name="checkbox" value= "{{user}}">
</div>
</li>
<div ui-view></div>
</ul>
</div>
</div>
<form id=userForm ng-submit="createGroup()">
<input class="btn btn-default" type="submit" value="Create Group">
</form>
</div>
Controller
$scope.createGroup = function() {
console.log("Entered createGroup ");
$("input[type=checkbox]:checked").each(function(i){
console.log("i.value :"+i.value);
$scope.people.push( i.value );
});
console.log("$scope.people : " + JSON.stringify($scope.people));
}
Just add object property as ng-model to the checkbox
<input type="checkbox" name="checkbox" ng-model="user.check">
angular.module("app",[])
.controller("ctrl",function($scope){
$scope.friendslist = [{"firstName":"sss","email":"ss#gmail.com"}]
$scope.createGroup = function() {
console.log($scope.friendslist)
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<div class="add-friends panel-primary panel" >
<div class="panel-heading text-center" >Add Friends</div>
<div class="panel_body">
<div class="row" id=myForm>
<ul class="list-group">
<li class="list-group-item" ng-repeat = "user in friendslist">
<div>
{{user.firstName}}
{{user.email}}
<input type="checkbox" name="checkbox" ng-model="user.check">
</div>
</li>
<div ui-view></div>
</ul>
</div>
</div>
<form id=userForm ng-submit="createGroup()">
<input class="btn btn-default" type="submit" value="Create Group">
</form>
</div>
</div>
Suggest you use ngModel directive as shown in the Angular documentation for input[checkbox].
Also, it might be useful for you to create a separate component (or directive) for each li in friendslist.
Hope it helps. Good luck;)

After calling ngif statement for edit state i get this error in console
Can't bind to 'ngif' since it isn't a known property of 'div'
I must mention that my first condition works well and that i have imported BrowserModule and CommonModule to app.module.ts
This is my tasks.component.html
<div class="container mt-5">
<div *ngIf ="tasks?.length > 0; else noTasks" >
<ul class="list-group" >
<li *ngFor = "let task of tasks" class="list-group-item">

</div>
<div class="col-sm-auto">
<button (click)="deleteTask($event, task)" class="btn btn-link"> Delete </button>
</div>
</div>
<div *ngif="editState && taskToEdit.id == task.id">

<div class="row">

</div>
</div>
</form>
</div>
</li>
</ul>
</div>
<ng-template #noTasks>
<h5>There are no tasks to list</h5>
</ng-template>
This line *ngif="editState && taskToEdit.id == task.id" contains a typo, and should read *ngIf. Please check.
I am quite new with AngularJS so excuse me if I'm asking a stupid thing. I'm trying to create a task manager for events with AngularJS + Mysql + PHP.
The layout is separated in two columns. In the left column there's an overview of staff, loaded by function getUsers() in app.js. By clicking the + button after each staffname the user_id is being posted in a mysql database table. The results of this table is shown in the right column, function getEventUsers() in app.js. I'm trying to find out how to reload or update the right table after clicking the + button. The functions itself are working correctly (they get json_encoded results from the .php pages), but the right column is not updating itself only after pressing F5 after each click it is showing the correct result. So the right column, so function getEventUsers() in app.js, has to refresh/reload after clicking on the + button.
Template
ng-app="myApp" is in the html tag
ng-controller="usersController" is in the body tag

$( "#id1" ).click(function() {
$( "#myModal" ).click();
});
</script>
It seems everything is okay for me, initial it was work but suddenly it is giving trouble, so what would be the mistake.
When ever I have click on register it is not pop-up the form, could you please let me know what mistake I have done.
$( "#id1" ).click(function(ev) {
ev.stopImmediatePropagation(); // sometimes click event fires twice in jQuery you can prevent it by this method.
$( "#myModal" ).modal(); // you should use native function of Bootstrap.
});
You dont need to add any jquery or js for that at first place.
So you need to add data-target attribute to target your myModal,
<li id="id1 "> Register</li>
So you markup should look like,
<ul class="loginbar pull-right">
<li class="hoverSelector"><i class="fa fa-globe"></i>
Help</li>
<li class="topbar-devider"></li>
<li id="id1 "> Register</li>
<li class="topbar-devider"></li>
<li><a>Login</a></li>
</ul>
Alternate to your js requirement you could do it on click of a tag,
$('ul.loginbar').on('click', 'li#id1 > a', function(){
$('div#myModal').modal('show');
});
I have three columns of equal width of col-md-4, however the middle one has an ng-show set on it and sometimes will not be displayed. Right now when friend requests come in and the right most col-md-4 comes up, it is showing up in the middle when the middle one is still hidden. How do I still have the middle col-md-4 chatWindow take up space even when it is hidden?
<div class="row">
<div class="col-md-4 friendListWindow" ng-init="getFriends()">
Friends List
<form ng-submit='addFriend(username)' name='addFriendForm'>
<input type='text' name='username' ng-model='username' required/>
<input type='submit' ng-disabled='!addFriendForm.$valid' value='Add Friend'>
</form>
Online Friends
<ul>
<span ng-repeat='friend in friends track by $index | orderBy:"name"' ng-click='startChat(friend)'>
<li ng-if='friend.online'>
<span class='friendService'>{{friend.service}}</span>
<span class='friendName'>{{friend.name}}</span>
</li>
</span>
</ul>
</div>
<div class="col-md-4 chatWindow" ng-show="activeFriend">
<div class="activeFriendBox">Chat with {{activeFriend.name}}</div>
<div class="messages">
<div ng-repeat='message in activeFriend.messages track by $index | orderBy:"timeStamp"'>
<span>{{message.from}}</span>
<span>{{message.message}}</span>
<span>{{message.timestamp}}</span>
</div>
</div>
<div class="sendMessage">
<form ng-submit='sendMessage(messageText)' name='messageForm'>
<input type='text' name='message' ng-model='messageText' required/>
<input ng-disabled='!messageForm.$valid' type='submit' value='send'/>
</form>
</div>
</div>
<div class="col-md-4 friendRequestsWindow">
<div class="friendRequests">
<ul>
<li ng-repeat='friend in friendRequests track by $index'>
<span>New friend Request from: {{friend}}</span>
<button ng-click='acceptFriendRequest(friend)'>Accept</button>
<button ng-click='ignoreFriendRequest(friend)'>Ignore</button>
</li>
</ul>
</div>
<div class="acceptedFriendRequests">
<ul>
<li ng-repeat='friend in acceptedfriendRequests track by $index'>
<span>{{friend}} accepted your friend request</span>
<button ng-click='acknowledgeFriendRequest($index)'>Acknowledge</button>
</li>
</ul>
</div>
</div>
</div>
You can use ng-show in the col content instead of the col itself
Instead of
<div class="col-md-4" ng-show="xxx">content</div>
Use
<div class="col-md-4">
<div ng-show="xxx">content</div>
</div>
As an example, I'm starting with html like this:
<div id="leftSide">
<div class="item">
<div class="editor">
<ul class="choices">
<li class="choice">This is choice</li>
</ul>
<input class="myChoice" name="myChoice[]" />
</div>
<p class="theChoice"></p>
</div>
<div class="item">
<div class="editor">
<ul class="choices">
<li class="choice">This is choice</li>
</ul>
<input class="myChoice" name="myChoice[]" />
</div>
<p class="theChoice"></p>
</div>
<div class="item">
<div class="editor">
<ul class="choices">
<li class="choice">This is choice</li>
</ul>
<input class="myChoice" name="myChoice[]" />
</div>
<p class="theChoice"></p>
</div>
</div>
The idea being, when I select an item i.e. .choice I want to add it to the input and the .theChoice. This way it displays what the user chose but they can edit it by typing the box.
I know how to do this with jquery. However, it will be a lot of overhead and I want to learn angular. I also know Angular can really clean this up.
I've used ng-model to mirror what a user types in the input box doing this:
<div id="leftSide">
<div class="item">
<div class="editor">
<ul class="choices">
<li class="choice">This is choice</li>
</ul>
<input class="myChoice" name="myChoice[]" ng-model="choice1" />
</div>
<p class="theChoice">{{choice1}}</p>
</div>
...
</div>
I've used ng-repeat to loop out three of the .item divs:
<div id="leftSide" ng-controller="leftSide">
<div class="item" ng-g-repeat="i in getNumber(number) track by $index">
<div class="editor">
<ul class="choices">
<li class="choice">This is choice</li>
</ul>
<input class="myChoice" name="myChoice[]" ng-model="choice1" />
</div>
<p class="theChoice">{{choice1}}</p>
</div>
...
</div>
and js:
myApp.controller('leftSide',function($scope,$index){
//three left boxes
$scope.number = 3;
$scope.getNumber = function(num) {
return new Array(num);
}
...
});
The problem I have is (obviously) selecting the .choice' is targeting all myng-models and not each that associate to its.editor. I'm certain I can use$indexto handle this and/or maybe ng-click. I'm just a little lost on how to target the correct one based on the.choice` I select.
I don't like the jQuery implementation, so I tried to solve your problem by pure AngularJS. You can run the snippet to check the answer:
var app = angular.module('my-app', [], function() {
})
app.controller('AppController', function($scope) {
$scope.number = 3;
$scope.choice = [];
$scope.getNumber = function(num) {
return new Array(num);
}
$scope.choiceClick = function(i) {
debugger;
$scope.choice[i] = 'This is choice';
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="my-app" ng-controller="AppController">
<div class="item" ng-repeat="it in getNumber(number) track by $index">
<div class="editor">
<ul class="choices">
<li class="choice" ng-click="choiceClick($index)">This is choice</li>
</ul>
<input class="myChoice" ng-model="choice[$index]" />
</div>
<p class="theChoice">{{choice[$index]}}</p>
</div>
</body>
