Uncaught Error: cannot call methods on sortable prior to initialization; attempted to call method 'option'

Question

I am getting this error when trying to use ui-sortable.

jquery-3.1.0.min.js:2 Uncaught Error: cannot call methods on sortable prior to initialization; attempted to call method 'option'

Thanks in advance.

Answer 1

The meaning of your error is : $this.draggable('enable'); is called before $this.draggable();.

Check the execution flow of your program : make sure that you have indeed initialized the plugin (e.g : called $this.draggable();) before trying to do anything with it.
