问题
I am currently trying to implement an ember-drag-sort nested list into my Ember.js app.
Is there a way to determine in the dragEnd action which "sub-list" the item has been dropped into? (e.g. a class name, id etc)
In my scenario, I am sorting ember data records that can belong to each other (i.e. a nested, 'tree' structure). When I drag one nested record "into" another (making the dragged record a child of the second record), I need to update the parent attribute in ember-data. My question is, how do you pass some id of the second record (the new parent) to the dragEnd action?
Is this even possible?
EDIT:
To put it another way, I want to be able to identify which list I have dropped the item into.
回答1:
targetList refers to the array on the dragged side of the component. For pushing the parent to the target list alongside the child, you can take a look at this twiddle.
