Select2: Why code demo copied don't work?
0
I have 10.000 row data to load in select.
improve performance I thought to load them with the "query" constructor.
I wanted to start from the example "e5" (Loading Data) on the documentation page.
I have also added demos of all "e10" - "Loading Array Data"
Except the first element "e10" all the others do not work. Who can help me ?
Where am I wrong?

data.results.push({ id: query.term + i, text: s });
