Dragula: get class and id of the dragged item

Question

I have seen this, but it does not work in my code. I am using Dragula, in my Angular2 application with Typescript.

I need to get the id of the element of the draged element. Here is a part of the typescript class:

 constructor(private dragulaService: DragulaService) {

    dragulaService.drop.subscribe((value) => {
       this.onDrop(value.slice(1));
    });

  }


  private onDrop(args) {
    let [e, el] = args;
    console.log("on Drop");
    console.log(e);
    console.log(el);
  }

I know the el contains the draged element, but how can i get the id out of an html element in typescript?

If el is the dragged element, then its id is el.id. That's how the DOM works. If you are dragging an element <div id="foo">something</div> and this element is assigned to el in your code, then el.id will be "foo".

If your html element is derived from an object model, there's a now neater way to obtain the id with dragula v2.0.

By using [(dragulaModel)], you can access the entire object model, including your object's id. For example:

In the html:

<div [(dragulaModel)]="listOfItems">
   <div *ngFor="let item of listOfItems">
   </div>
</div>

Then, in your Angular service:

this.subs.add(
   dragulaService.dropModel().subscribe((value) => {
      // prints the item's id
      console.log(value.item.id);
   })
)

The best part of this method is you gain access to all the properties of the dragged item with value.item amongst others. See documentation: https://github.com/valor-software/ng2-dragula#special-events-for-ng2-dragula

Who gave this a -1? This helped me after days scourging the internet for an answer as to how to pass a model object. Granted I'm new to Angular, but his resolved my issue. — Lukas, May 17 '19 at 18:42
