callback for each item in {#each}

[Nyx2022]

Describe the problem

i'm using {#each} to render a list,and i wanna process the new generated dom element after one item has processed finish,but now there maybe no way to do this

Describe the proposed solution

add a callback attr to {#each} to execute function and cna get all new generated dom

Importance

i cannot use svelte without it

There is no guarantee that any DOM will be generated at all.
Also, #each is fairly bloated already ({#each expression as name, index (key)}) and adding additional stuff to it would not improve the situation.

If you need access to DOM elements, you can define an action on a wrapper element in the #each or use bind:this (you would need to bind to an array/object via an index/key).

ok,thank you,i will try the action to check if it can realise my need

[Conduitry]

Closing. Actions and bind:this are the ways to do this. We don't want to add an {#each}-specific syntax for something we already have.
