Saving the Selected Date to Session Storage

Ultimately, what we want to do is set up the Date panel so that when it’s displayed, it will check the database for any records entered for that date and display them as an edge-to-edge list. This requires that the Date panel know which date the user tapped on the Dates panel.

We also want to allow the user to add and delete entries from the database, so we’ll have to add support for the + button that already exists on the Date panel, and for the Delete button in the Date panel entry template (more on this later).

The first step is to let the Date panel know which item the user clicked when she navigated to it from the Dates panel. With this piece of information, you can calculate the appropriate date context. To do so, you need to add some lines to the document ready function in kilo.js:

$(document).ready(function(){ $('#settings form').submit(saveSettings); $('#settings').bind('pageAnimationStart', loadSettings); $('#dates li a').bind('click touchend', function(){ var dayOffset = this.id; var date = new Date(); date.setDate(date.getDate() - dayOffset); sessionStorage.currentDate = date.getMonth() + 1 + '/' + date.getDate() + '/' + date.getFullYear(); refreshEntries(); }); });
