To solve the problem of server side communication you have to make use of AJAX. This is because there is no server present on a smartphone like iphone, blackberry and android. Let me give u a basic example. Let say in you app you want to log a user his details in the database in your button <button onClick="doLogin()">LOGIN</button> The in your javascript file you will have function doLogin(){ // Code to communicate with your database using AJAX. } |

Since ur developing a cross platform mobile app, I would seriously suggest u use a template just to ensure that your web app is compatible on a broad range of mobile devices & browsers, a template that im particuarly fond of is HTML5 BOILER TEMPLATE its in its 3rd version so its very robust you can get it here http://html5boilerplate.com/. Secondly switch to HTML5, it quite simple really, all you need do is put this declaration at the top of ur web page: <!DOCTYPE html> and thats it ur using HTML5 ! U can now take advantage of its HTML5 offline ability by using cache manifests, what it does is to load all HTML, CSS, and Javascript files (that you will specify in a manifest file) unto the phone or desktop and then when there is no internet connection or ur in offline mode the webb app will still work. Scripts or functions that require a connection to a web server will still not work in offline mode. U can actually use this to increase the performance of online website as well. Another cool feature you can take advantage of is called local storage which basically is a NoSQL type database called IndexedDB , this database is stored in the browser (not in a web server) and enables you to build dynamic offline apps in HTML5. The default allocation size is 5MB , however if you package it as a Chrome App you will be granted unlimited storage as long as you follow certain guidelines designed to make sure u dont abuse this feature. Other cool features of HTML5 include support for multi-touch and geo-location as well. HTML5 can also communicate with functions in Native apps, so you can call the accelerometer function from HTML5 using a bit of javascript. Concerning how to include pdf in your web app, simply create a new folder, u can name it pdf or still use d rootfolder in ur www directory folder, upload the pdf into it and reference it accordingly using <a href="pdf/test.pdf">. Most webkit mobile browsers will automatically open the pdf file or might prompt you to save. So depending on the features of ur mobile web app u can actually use HTML5, CSS3 and Javascript and a tiny lil bit of PHP |
