10 Useful Frameworks To Develop HTML-Based Webapps for Touch Devices

August 26, 2010 Leave a comment

I came across this article about different frameworks for building Mobile Apps/ Web sites by Antonio Lupetti

Intro of the Article is:

Make HTML-based touch applications. Easy.

In the last two years the rapid growth and diffusion of touch devices such as iOS or Android based platforms has forced developers and web designers to rethink the model of their own webapps for the new “touch experience” introduced by the iPhone in 2007.

During this period several frameworks have been released to help web developers implement quickly applications for this kind of touch devices. Here is a collection of some useful frameworks to develop easily HTML-based webapps that will work on all popular smartphone and tablet touch platforms.

Few frequently used Regular Expressions by me.

August 13, 2010 Leave a comment

In ColdFusion:
1) To match a valid UK postcode and returns an array with one item of valid postcode otherwise returns array with no item in it:
Pattern to test (with or without spaces):

^ : is for start of the string

$: is for end of the string

?: zero or one letter (optional)

{1,2}: minimum 1 or maximum 2 characters

Pattern Example
A9 9AA M1 1BA
A99 9AA N12 1UD
AA99 9AA RG6 1WG
Special case for National Girobank

<cfset arr = REMatch(“^[A-Za-z]{1,2}[0-9R][0-9A-Za-z]?[[:space:]]?[0-9][ABD-HJLNP-UW-Zabd-hjlnp-uw-z][A-Za-z]$”,request.postcode)>
<cfif len(arr) GT 1>
<cfreturn true >
<cfreturn true >

2) Another one for UK post code, little bit complicated

<cfset arr = REMatch(“^([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([A-Za-z][0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z])))) {0,1}[0-9][A-Za-z]{2})$”,request.postcode)>

Few references for UK Postcode regex)

Ref Site Link 1, Ref Site Link 2

3) To validate number with minimum 11 char and maximum 14 car using isValid function


4) To remove all characters from the string except alpha numeric:

REReplace(stringvar, “[^a-zA-Z0-9]”,””,”All”);

In JavaScript:

To restrict any thing except alpha numeric (case insensitive)

string.replace(/[^a-zA-Z0-9]/g, “”)

To Replace brackets, dots and spaces from string globally

string.replace(/[\(\)\.\-\ ]/g, ”)

In ActionScript:

1) Phone number check through regEx validator:

private const UK_PHONE_NO_REGEX:String = ‘^[0+][0-9]{10,14}$’;

number can start with 0 or plus (+) , with minimum 10 and maximum 14 characters

2) removes double quotes from string:

var pattern1:RegExp = new RegExp(‘”‘, “g”);


JavaScript Regular expression replacement:

Add comma separator to numbers like 10,000.00

variable.toString().split(“”).reverse().join(“”).replace(/(\d\d\d)(?=.)/g, “$1,”).split(“”).reverse().join(“”);
if you want to separate by (.) dot than replace comma with dot in here “$1,” in above string.

How to fire event from javascript (Dynamic)

August 13, 2010 Leave a comment

I had a requirement to call onchange event of a select box (combo box) from JavaScript and the function has an input param as event. I found one article which helped me to achieve this for one of my clients mobile web site (Land Rover UK), when I was working at

The article link is Firing Javascript Events (like onchange)

Here is the code which I had to change a little bit to fit in my code:

function fireEvent(element,event){
if (document.createEventObject){
// dispatch for IE
var evt = document.createEventObject();
return element.fireEvent('on'+event,evt)
// dispatch for firefox + others
var evt = document.createEvent("HTMLEvents");
evt.initEvent(event, true, true ); // event type,bubbling,cancelable
return !element.dispatchEvent(evt);

Here is the code for how to call this method:
