I have a simple rails app with a model Task, which has 10 rows. It does not matter what’s inside this table. On the index page I can see all 10 elements and I need to arrange them in proper sequence, when I did this, I should see a message “Done”.
If I understand correctly this should be implemented in javascript, because page should not be reloaded, right?
I want to be able to rearrange the elements via drag and drop.
How I can realize that function?
I would start with here -> http://jqueryui.com/demos/sortable/
You can sort and its quite simple as there great examples on the site how to do this and hook into events.
