Question

I have a simple page with two lists. Using jQuery I have set the two lists as sortable and connected them together so I can add and remove from the list. This all works well.

I have come to the part of the feature where I need to save the results into the data store. When the user clicks on a submit button, there is an asynchronous request to an MVC controller that accepts a collection of strings.

I have two ideas on how to handle this scenario.

Idea one, remove all existing elements and re-create based on what is in the collection.

Idea two, loop through the list and add or update the sort order based on if a record already exists.

What this best way to do this and it there an option I have missed?

I’m using asp.net MVC with jQuery but this shouldn’t matter.

Answer 1

Either method should work for your request. The dumping and recreating “should” be less resource intensive than the insert and update method in idea two.
