javascript - Vue.js Sortable list - updating model and saving position on change through AJAX -


fiddle:

https://jsfiddle.net/fierflash/0h6ul4ek/2/

objective:

when re-order takes place(through sortable), send ajax request backend save new positions of tasks

whats v-sortable?

http://am2studio.hr/blog/creating-dynamic-table-with-vue-js/

problem

  • the markup updated model not updated. in case value of task.position remains same when re-order takes place.
  • how should $watch this(if needed)? values should put in?

how solve this?

the main problem running approach trying update position using input type="hidden". vue's v-model not support input type (and unfortunately doesn't emit error message in case either).

since trying update position after drop ends, why not walk array , set afterwards this?

that.value.foreach(function (task, index) {     task.position = index + 1; });
