Client-Side HTML / CSS / JavaScript Mobile Application
Assignment 1 Mobile client application IT
You are to implement this app using HTML5, CSS, and JQueryMobile. The app is used by a chicken farmer who the five varieties of chicken on his farms. A number of individual chickens exist for each species and an ID number is used to identify these. For each individual chicken, the farmer wishes to record data that can be used to determine how well that chicken performs compared to others.Assignment 1 Mobile client application IT.
The app should be based on a multi-page template structure. The client-side application home page is shown in Fig. 1. The Foghorn, Little, Tweety, Hawk and Bertha buttons should link to pages in a JQueryMobile multi-page structure.
Images for the page/views required to implement the assignment are given in the following figures. Please note that the illustrations are for reference only, and your actual pages will be based on the CSS style-guide in use on your actual mobile device.
Home page view
This is the opening page for the app. A user clicks on a page link and is transferred to that page.
Chicken data entry view
The pages for entering the chicken data are all the same so it makes sense to use one html page to show the basic structure and then use Javascript to customise parts of the page, based on what chicken variety we clicked on the home page. The view shown is for the Foghorn variety.
The header has titles from the variety sequence {Foghorn, Little, Tweety, Hawk, Bertha} based on what button is pressed on the Home page. It also has a Clear and Show logs buttons visible in the header bar. The Clear button will clear the values in all the text entry fields on the page.
The footer has 3 buttons. The Next button will take you to the next element in the sequence {Foghorn, Little, Tweety, Hawk, Bertha}. The Previous button will take you to the previous element. The Home button will take you back to the home page.
The content of a chicken page has text entry fields with labels, ID: Weight (g): , Eggs laid:, Grain eaten (g): and a drop-down Condition field (“”, “Poor”, “Average”, “Good”). Each text entry field initially has the hint shown and are all number entry fields.
When valid data is entered into all the text entry fields the Save log entry button can be pushed to save a log for the chicken. If any of the data values are out of range or nothing is in a text entry then an alert should be shown to indicate the problem, for the id.
A second dialog must also be shown when there were problems saving the log, alternatively, a success dialog will be shown. Any number of log entries can be made to a chicken variety in this manner.
Chicken logs view
When the Show logs button in the chicken’s data entry page header is pressed, the current date/time and location should be added to the data structure used to store the chicken data values being recorded. Pressing this button also triggers a request for the location (latitude/longitude) to be added to the chicken data. The log entries should then be saved in the device’s localStorage. A chickens logs page is then shown with all the saved logs for the variety listed, as shown in Fig. 5a. Fig. 5b shows the display when more than 1 entry has been saved.
Send button
The Send button on the chicken logs header bar is used to send the data over the WWW and clear the particular chicken varieties logs. This will be done in the second assignment. In this assignment, this is used to clear all this chicken variety data in the localStorage, and thus clear the existing chicken variety logs. As this deletes data you must present a dialog box to the user with the choice to either send the logs or not.
If the Yes button is pressed the Send logs dialog is presented and we return the chickens view. If the No button is pressed we just return to the chicken view page.
