Record set

The story so far

Persisting record sets

There's a problem with the course data app in the previous lesson. It doesn't remember anything. We created a record set when the page loads:

(function($) {
    //Initialize course catalog.
    var catalog = [
        {
            id: 42,
            title: "Web apps for happy dogs",
            maxEnrollment: 40,
            location: "Monty Hall 301"
        },
        ...
    ];

It was lost when the page ended.

We want something like this:

Records are stored in JS objects. You can make HTML to show what is in an object.

Showing a course list

Try the course catalog page. It starts off empty:

When you click the button, you see a course list:
