Svelte Sortable drag-and-drop list doesn't update when Svelte Store changes #1946
Comments
Sortable is a one way binding, where Sortable is the controller. It doesn't listen to your data. This is unfortunate. AT the time of this being created, data driven development wasn't considered for this project. |
@waynevanson is re-creating the sortable js instance every time the data changes a viable solution? |
Check out Store in the read me. That might do what youre after. I've never used it myself. |
@kantord did you ever figure this out? I'm running into the same thing, and my first attempts at recreating the sortable aren't working. I'm wondering if this is viable and I'm "just doing it wrong", or if it's never going to work that way. |
Hi @samf, not yet, I have been focusing on other things, and there's a lot of high prio things other than this. Do you have some code example for your specific issue btw? |
I can second this "issue". Working on a solution. Thank you for SortableJS, i enjoy using it Demo: edit: "solved" in a way i'm ok with: Instead of mutating the original data object, make a copy upon initializing Sortable.. then, on sort, update the svelte data |
If you don't mind little overhead, you can use the #key block now. Ideally you would probably implement Sortable as an action using |
Thanks @janvotava, your comment saved me. :) |
I am building a component using Svelte in which you have a list of words and you have to arrange them in the correct order by dragging the words to the answer section, for this, I am using SortableJS.
To store the answer and the words you can use I use svelte stores and everything works correctly. Now, I am trying to do the same but with an ʻonClick` event. But I have a bug where the store values are updated but the view does not.
To show the options and the answers I am doing this:
and if I replace the
get
in{#each get (answer) as chip, index}
with$answer
, the ʻonClick` event works but now the drag behaves strangely and with bugs.Here is a codesandbox with both of the alternatives explained above
