I am working on my first ever amplify app that records location,activity, Date of Entry.

The localstorage has the key "__amplify__activities" and the following data:


What I'd like to do is :

1. display the results in batches of 10.
2. display total number of entries.

Any help is appreciated.

Ended up doing it this way (to display total # of entries).

var itemCount = $(data[Object]).length;
if (itemCount < 1){
    $( "#itemCount" ).html("Welcome to activity log. Please add your name.");
      } else {
        $("#itemCount").html("You have  <span class='label'>" + itemCount + "</span>activities.");

If there is a better way to do it, please let me know.

Hi there!

Most of what you are doing is fine, but I believe the first line should be this:

var itemCount = amplify.store( "activities" ).length;
