Form in Angular Dialog - Get form data after dialog close - angularjs

Question

I created a webpage with Angularjs and Laravel. It's an event page.
In my admin-panel I can manage all events.
When I click at "Bearbeiten" a new window appears.
At the bottom I can add/remove different attractions. When I submit the form, I want save the new data in the database, but I don't know how I can get the data from the formula. I tried different thinks and yes I used google.
When I click at "Bearbeiten" following code will be executed:
<md-dialog-content style="padding: 20px;">
<div layout-gt-sm="row">
<md-input-container class="md-block"flex-gt-xs>
<label>Name (Bsp: Schützenfest, Kirmes, Sommerdom)</label>
<input value="{{ $data['event']->name }}" name="event_name">
</md-input-container>
<md-input-container class="md-block">
<label>Stadt (Bsp: Hannover, München, Köln)</label>
<input value="{{ $data['event']->city }}" name="event_city">
</md-input-container>
</div>
<div layout-gt-sm="row">
<md-input-container class="md-block" style="margin: 0" flex-gt-xs>
<label>Straße</label>
<input value="{{$data['event']->street }}" name="event_street">

I am not really good with angular. Maybe are here some experts!

Answer 1

Since the data is already populating on the popup, I will assume you have correctly passed the data array to the function/module responsible for the popup.
Now, all you need is to update the array containing variable data fields that you are modifying. You will need to remove the data you chose to remove from the array, or keep adding if you are adding new values. You will then need to pass updated array as you click on ABBRECHEN and need to update the new values in the DB. The data removed from the array will create empty spaces in the array, you can either remove it on the Angular or Backend, or simply put the logic to skip if particular index is null/undefined.
