How to create a button (similar to FAB speed dial from angular material) or something similar to display a small window next to the button clicked, the small window only has a text area and a button inside, I would like to use Angular Material preferably or AngularJs routing or Jquery.
I have been trying using bottomsheets and FAB speed dial from angular material but without success.
I would appreciate any help.
If angular material doesn't have the functionality you are looking for built in (which I don't believe it does), you should just write a directive for it yourself. I would 'probably' write a directive that, when clicked, reveals a sibling or child element.
You could use a directive with a non-isolated scope to pass the data from the box you are creating to the rest of your application.
The code would probably look roughly something like this:
angular.directive('smallInputModalButton', function() {
scope: {}, // or false, up to you
controller: function () { $scope.isShown = false; },
template: '<div ng-hide="isShown"><input></input><button></button></div>',
link: function( scope, elem, attrs, controller ) {
elem.on('click', function(e) {
e.preventDefault();
scope.isShown = !scope.isShown;
});
}
}
Make sure you position the element that has the smallInputModal attribute on it relatively, with the #isShown div positioned relatively so that you can easily nest them next to each other.
If you want to be really thorough, you could create a directive that acts as a button, which communicates with another directive which has logic for showing/hiding the modal.
If you look in popular libraries, including ngMaterial, they do something of that sort.
For simple use cases, the answer above will work fine.

I'm new to Angular/CSS and I've been checking out some stuff about how to flip a card and how to apply different rotations and animations. I've both flavours where you can flip on hover over and flip on click. I have my new ng-app that has a controller that toggles a css class for flipping a div and all of that works fine. However what I would like to achieve would be something like that:
http://jsfiddle.net/jwhazel/AaU6v/11/
Which is in JQuery and honestly I don't know how best it would translate into the Angular world. I have started creating a directive that tries that but I'm kind of stuck. Basically all I've got is the link function that binds the element click which is my card but I can't even get access to the position of the element.
link: function(scope, element, attributes) {
element.bind('click', function(){
And for now I'm logging some stuff to proof is getting there which it does. But things like offset() or getBoundingClientRec don't work. I'm using Angular 1.4.0.
Any tips are much appreciated.
Thanks in advance.

I've recently switched from jQuery to Angularjs and I am in the process of re-coding some pagination logic for the links ("Next", "Previous", etc.) that were written in jQuery-style Javascript previously.
Each link has an ngIf condition (for example, the "Previous" link won't show if you're on page 1) plus an ngClick event, which essentially updates a scope variable called $scope.pagination.position that determines which results are displayed in the table.
My original code was something like this (simplified for clarity):
Template
<a ng-if="pagination.position > 0" ng-click="pagination.first()">First</a>
Controller
$scope.pagination = {
first: function() {
this.position = 0;
}
}
Then I learned more about directives, and how most DOM elements that aren't static HTML should be created using a directive. So I switched each link (since each has it's own display rules and behaviour on clicks) to its own directive, like so:
Template
<a pagination-first></a>
Directive
app.directive('paginationFirst', function() {
return {
link: function(scope,el,attr) {
scope.pagination.first = function() {
scope.pagination.position = 0;
}
},
replace: true,
template: '<a pagination-first ng-if="pagination.position > 0" ng-click="pagination.first()">First</a>'
}
});
I'll cut straight to the chase : am I doing directives wrong? All that's happened, from my perspective, is I've flipped from having logic in my template to having a template in my logic, and I've defined the click event function in the directive rather than in the controller.
Is this even an appropriate time to be using a directive?
I'd like to learn best practices, so I'd love to know if I've missed the point and if the original templated-based ngIf and controller function approach was fine, even with longer and more complex ngIf conditions than the one shown.
If I want to add specific behaviors to a dom or dom list then I normally create a directive. As per angular js perspective the dom manipulation should only be done through directive (For me it is the best place, sometime I have to disobey this due to my lack of knowledge ). I specially found directive use full while creating a widget. In one of my project there was a part where a section is dedicated to display an image and also upload the image. I just use the directive on the top div, with the help of link function I attached the event handlers to various child dom. And as my project doesnot require an isolated scope (as this widget was all used in a single project and the outer scope was under my control) . So it worked like a charm. I cerarted the directive once. And used that widget through rest of the project as it's behavior and design (of the widget ) was same through out the project. For the pagination widget you can create a directive. Take the directive attibutes value as the input of the pagination parameters. Like calling script, limit offset. Container identifier to update the content. Then you can solely concentrate on the pagianation behavior. But from my experience (as I am also not so experienced in angular js), sometimes it becomes a little hectic to develop a directive and and use that throughout the project. As in some places we need to modify the behavior of the directive. And for this it may breaks elsewhere. But I know as I learn more I will be more efficient to handle this kind of situation. Hope my experience will help you.
I am trying to create a live HTML editor with AngularJS, where user can drag and drop some DOM elements to a container and it will render the final HTML page, for example, there is a button (or whatever) that says "Drag me to create an input", then user will drag that item into the container and an input field will be rendered...
I've been trying ngDraggable module but isn't what I needed...
I think a way is to hold the HTML code into some $scope variable, and when the user drops the button into the container, $scope.input which contains <input type="text" placeholder="Something"/> will be rendered inside container...
My final step is to enable inline edit to thoose HTML elements generated, in order to let the user create some content agains that final template.
When the user finish, the whole HTML code will be saved somewhere or downloaded...
I don't need something complex, just a few predefined elements that can be dropped...
I hope I've explained it correctly.
There is some example found at http://nboychev.com/tests/angular/Drag%20Drop%20iFrame%20using%20Angular%20JS%20Directive.html that does exactly what I want (see source), BUT:
It's using jQueryUI (Which I don't want to use, but if its needed then I will)
It isn't working on my project. I must say that I'm using RequireJS, but everything works on my angular app but the directives mentioned on the link above. Draggable is not working, I do not have any errors and I've checked that the code is being executed, doing some console.log() stuff, but still not working...
But it contains what I want, draggable stuff with HTML injected that renders content on an iframe (or a div, or whatever) and that new content is also droppable, to insert more stuff inside that code. Give it a try, and guide me a little. Thanks
I think it's better if you try using something as jui
On the other hand you can try implementing your own directive:
<br>
<h4>Drop Area</h4>
<div droppable jui-options="{addClasses: false}" class="drop-area"></div>
<div class="read-out">
<span class="text-info"><strong>Draggable ID</strong></span>: {{obj.id}}<br><br>
<span class="text-info"><strong>Content</strong></span>: <span ng-bind-html="obj.content"></span><br><br>
<span class="text-info"><strong>Actual Content</strong></span>: {{obj.content}}<br><br>
</div>
</div>

Sounds like a fun project.
This is a simple link function using JqueryUI and Angular. You'll need an HTML element in scope with class "draggable". Use destroy() when finished.
Adding HTML to the DOM from the scope, check out this solution by Josh David Miller: http://jsfiddle.net/paulocoelho/fBjbP/2/
Or for simple HTML elements for visual display only you could try using ngBindHtml, ngRepeat and ngSanitize. Then adding / removing HTML elements to and from an array should display them in a container.
link: function($scope, $elem, $attr){
$elem.find(".draggable").draggable({
start: function(event, ui){
$(ui.item).addClass("shadow");
},
stop: function(event, ui){
$(ui.item).removeClass("shadow");
// DO SOME ANGULAR STUFF HERE
}
});
}
I'm really new to Angular, but learning quickly. However, the one problem that I haven't been able to find an answer for yet is how I can pass around HTML snippets with bindings attached.
e.g. With jQuery I could do something like
var $div = $('<div id="test"><button>CLICK ME!</button></div>');
$div.delegate('button', 'click', function () { alert('CLICKED') });
Then I could pass around this $div variable to other objects. For instance I would use this pattern to separate page specific content from the code of a modal Singleton that encapsulated general functionality.
e.g.
var name = "The Dude";
var $div = $('<div id="test"><button>CLICK ME!</button></div>');
$div.delegate('button', 'click', function () { alert('Hi, ' + name) });
Modal.open({ content: $div});
How can I achieve something similar with Angular?
You should not pass around template code in the controllers, that's not the "angular way". If you have to do DOM manipulation it should stay in a directive. A lot of jQuery developers fall into this trap of thinking like you do with jQuery. But anyways here's how I would solve this problem:
I'm writing this in a directive so it's more modular. You could move this into a controller and it'll work just fine.
Code in plnkr here
In the directive you have a template which contains your code and you can have a ng-click binding which can control a click action to open the modal.
Now as far as the content in the modal is concerned, making the actual template code modular so you can decouple the content from the template depends on if/what angular plugins you're using. They all do something similar but the names may be a little different. For example, if you're using ui-bootstrap(which is awesome by the way, if you dont use any plugins I'd highly recommend it) there's a resolve function that takes a variable as an argument and you can display that in the view. That's exactly what you want to send custom content to the modal(eg. name)
I have this AngularJS app. Everything works just fine.
Now I need to show different pop-ups when specific conditions become true, and I was wondering what would be the best way to proceed.
Currently I’m evaluating two options, but I’m absolutely open to other options.
Option 1
I could create the new HTML element for the pop-up, and append to the DOM directly from the controller.
This will break the MVC design pattern. I’m not happy with this solution.
Option 2
I could always insert the code for all the pop-ups in the static HTML file. Then, using ngShow, I can hide / show only the correct pop-up.
This option is not really scalable.
So I’m pretty sure there has to be a better way to achieve what I want.
Based on my experience with AngularJS modals so far I believe that the most elegant approach is a dedicated service to which we can provide a partial (HTML) template to be displayed in a modal.
When we think about it modals are kind of AngularJS routes but just displayed in modal popup.
The AngularUI bootstrap project (http://angular-ui.github.com/bootstrap/) has an excellent $modal service (used to be called $dialog prior to version 0.6.0) that is an implementation of a service to display partial's content as a modal popup.
It's funny because I'm learning Angular myself and was watching some video's from their channel on Youtube.
The speaker mentions your exact problem in this video https://www.youtube.com/watch?v=ZhfUv0spHCY#t=1681 around the 28:30 minute mark.
It comes down to placing that particular piece of code in a service rather then a controller.
My guess would be to inject new popup elements into the DOM and handle them separate instead of showing and hiding the same element. This way you can have multiple popups.
The whole video is very interesting to watch as well :-)
Create a 'popup' directive and apply it to the container of the popup content
In the directive, wrap the content in a absolute position div along with the mask div below it.
It is OK to move the 2 divs in the DOM tree as needed from within the directive. Any UI code is OK in the directives, including the code to position the popup in center of screen.
Create and bind a boolean flag to controller. This flag will control visibility.
Create scope variables that bond to OK / Cancel functions etc.
Editing to add a high level example (non functional)
<div id='popup1-content' popup='showPopup1'>
....
....
</div>
<div id='popup2-content' popup='showPopup2'>
....
....
</div>
.directive('popup', function() {
var p = {
link : function(scope, iElement, iAttrs){
//code to wrap the div (iElement) with a abs pos div (parentDiv)
// code to add a mask layer div behind
// if the parent is already there, then skip adding it again.
//use jquery ui to make it dragable etc.
scope.watch(showPopup, function(newVal, oldVal){
if(newVal === true){
$(parentDiv).show();
}
else{
$(parentDiv).hide();
}
});
}
}
return p;
});

for a simple way of doing modal dialog with Angular and without needing bootstrap
Edit: I've since been using ng-dialog from http://likeastore.github.io/ngDialog which is flexible and doesn't have any dependencies.
Angular-ui comes with dialog directive.Use it and set templateurl to whatever page you want to include.That is the most elegant way and i have used it in my project as well.
You can pass several other parameters for dialog as per need.
