I know this is less than ideal, because it forces users to have to process the instructions, and then execute them. Somewhere in there you lose them and they never execute the desired action.

It got me thinking: is there a way to have the source code in front of them in one click? A few Google searches later, and the answer was yes!

Using JavaScript you can open a new window to display the source code view of the current window:

PLAIN TEXT
JAVASCRIPT:
  1. window.open('view-source:' + window.location.href, 'mysource');

Voila! How easy was that? Now it's your turn.

For example your page template may be cycling through QOTDs, testimonials, offers, specials, and so forth.

To retrieve a random row in MySQL, use the ORDER BY RAND() statement to randomly order the rows of a table. Then use LIMIT x to retrieve the first x rows from the randomised representation of the table.

For example:

PLAIN TEXT
SQL:
  1. /*  Retrieve 5 random special offers to display in your e-commerce store's sidebar */
  2. SELECT  offer_id
  3. FROM    special_offers
  4. ORDER BY RAND()
  5. LIMIT 5

Of course, we can make our query as complex as needed, and then randomly order the resultset.

PLAIN TEXT
SQL:
  1. SELECT  so.offer_id, i.title
  2. FROM    special_offers so
  3.           LEFT JOIN items i ON (so.item_id = i.item_id)
  4.           LEFT JOIN item_categories ic ON (i.item_id = ic.item_id)
  5. WHERE   ic.category_id = 2344
  6. ORDER BY RAND()
  7. LIMIT 5

These could be temporary files, log or debug files, and so forth. These are files that you can safely ignore when executing commands such as svn commit and svn st. The following shows how to configure your svn client to ignore particular files in your working copy.

svn propedit svn:ignore /path/with/files/to/ignore/

svn opens up your text editor of choice

Use file patterns to indicate which files to ignore from version control. Each pattern goes on a new line. e.g.

log_12*.log
*.tmp

Save your file and exit

Now whenever you perform commands like svn st or svn commit, svn will ignore files with the patterns you specified in the directories that you specified.

This addendum post shows how to create an inherited class from a parent class.

The concept is simple.

  1. Declare and define your parent class
  2. Declare and define your child class without defining the parent-child relationship
  3. Add a new instance of your parent class to your child class' prototype. Now the child class has access to the parent class' properties and methods. This last step may seem counter-intuitive, but the example below helps to clarify what I mean.
PLAIN TEXT
JAVASCRIPT:
  1. function SuperHero(heroID, p1, p2, p3) {
  2.     ...
  3.     ...
  4.     ...
  5. }
  6.  
  7. /* Do some extending of SuperHero's prototype here */
  8.  
  9. //Now let's define our child class - note that we do not initially define the parent-child relationship
  10. function AlienSuperHero(heroID, homePlanet, race, p1, p2, p3) {
  11.     ...
  12.     //Now we indicate the parent-child relationship
  13.     this.prototype = new SuperHero(heroID, p1, p2, p3);
  14. }
  15.  
  16. /* Do some extending of AlienSuperHero's prototype here */

Usage would be along the lines of:

PLAIN TEXT
JAVASCRIPT:
  1. var MartianManhunter = new AlienSuperHero(3454, 'Mars', 'Martian', 'Flight', 'Telepathy', 'Shapeshifting');
  2. if (fire) {
  3.     //This is a method defined in the parent class
  4.     MartianManhunter.losePowers();
  5. }

]]> http://vinoaj.com/blog/2007/06/class-inheritance-in-javascript/feed/ 0 Creating classes with Javascript http://vinoaj.com/blog/2007/06/creating-classes-with-javascript/ http://vinoaj.com/blog/2007/06/creating-classes-with-javascript/#comments Tue, 05 Jun 2007 10:51:22 +0000 admin http://vinoaj.com/blog/howtos/creating-classes-with-javascript/ Javascript is a prototype-based language rather than a class-based language (e.g. Java). For an explanation of the difference, see Mozilla's comparison of class-based and prototype-based languages.

In short, in a class-based language, objects are created by instantiating classes. The classes' list of properties and methods cannot be altered (e.g. added to) at runtime. A prototype-based language does not have the notion of a class. Everything is an object. A prototype-based object can have its list of properties and methods modified during runtime.

The examples below show how to create a class in Javascript. First we define a function that will behave as our constructor. Then we extend that function's prototype to include further functions that will behave as the class' methods. Note the use of the "this" keyword to refer to the prototype of the current object.

PLAIN TEXT
JAVASCRIPT:
  1. //This is our constructor
  2. function SuperHero(heroID, p1, p2, p3) {
  3.     this.heroID = heroID;
  4.     this.name = null;
  5.    
  6.     this.power_1 = p1;
  7.     this.power_2 = p2;
  8.     this.power_3 = p3;
  9.    
  10.     this.power_ultimate = p1 + p2 + p3;
  11. }
  12.  
  13. //Now add some methods to the class
  14. SuperHero.prototype.getPower1 = function() {
  15.     return this.power_1;
  16. }
  17.  
  18. SuperHero.prototype.losePowers = function() {
  19.     this.power_1 = null;
  20.     this.power_2 = null;
  21.     this.power_3 = null;
  22. }
  23.  
  24. SuperHero.prototype.setName = function(name) {
  25.     this.name = name;
  26. }
  27.  
  28. SuperHero.prototype.alertProfile = function() {
  29.     var str = 'Hero Profile:\n' +
  30.               'Name: ' + this.name + '\n' +
  31.               'Name: ' + this.name + '\n' +
  32.               'Name: ' + this.name + '\n' +
  33.               'Name: ' + this.name + '\n' +
  34. }

And now we have a simple class with a few simple properties and methods. Usage of the class would be something like:

PLAIN TEXT
JAVASCRIPT:
  1. var Superman = new SuperHero(2331, 'Flight', 'Speed', 'Strength');
  2. Superman.setName('Superman: Man of Steel');
  3. var power_1  = Superman.getPower1();
  4.  
  5. if (kryptonite) {
  6.     Superman.losePowers();
  7. }
  8.  
  9. Superman.alertProfile();

These pages usually have a contact form, where an enquirer can leave their name, e-mail, and request or comment. When they submit the form, a copy of the message is e-mailed to the site owner. The spambots try and submit messages that usually contain gibberish but also multiple URLs to spam sites. Something had to be done to prevent site owners from receiving hundreds of spam messages a day.

I considered a few methods for preventing the bots from visiting the enquiry page. These included firewall configuration, user-agent detection, rudimentary parsing of the messages, captcha systems, and so forth. These methods were either too cumbersome to implement, could be circumvented, or spoiled the user experience for a genuine user. The latter was a critical concern.

Enter Akismet

The Akismet API is an open API used to assess the spam score of comments left or enquiries made on a site. It is in widespread use as a plugin for WordPress blogs. Its effectiveness has become a must-have plugin for WordPress installations. The Akismet API however can be applied to any site or application capable of making HTTP requests.

First you need an API key. You can obtain one by registering for a WordPress.com user account (you do not need to have an active WordPress blog). Your API key will be e-mailed to you once you have activated your account.

When you read those timestamps later, you can convert them to local time.

Local time to UTC time

PLAIN TEXT
PHP:
  1. date_default_timezone_set('Australia/Sydney');
  2. $time = gmmktime($hr, $min, $sec, $mon, $day, $yr);
  3. $date = gmdate('d/m/Y H:i', time());

date_default_timezone_set sets the default timezone for all date & time operations.
gmmktime is analogous to mktime except it takes in local time values and creates the corresponding UTC timestamp.
gmdate similarly takes in local time values and creates the corresponding UTC date & time.

UTC time to Local time

PLAIN TEXT
PHP:
  1. $ts_utc = read_timestamp_from_db(); //Some custom function in your script
  2. date_default_timezone_set('Australia/Sydney');
  3. $offset = date('Z');    //Timezone offset from UTC in number of seconds (can be +ve or -ve)
  4. $ts_local = $ts_utc + $offset;

PLAIN TEXT
PHP:
  1. header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
  2. header("Expires: Tue, 03 Jul 1979 00:00:00 GMT");   // Date in the past

The first header tells the client that the page must not be cached.
The second header is a backup, and tells the client that the page expired a long time ago in the past, and it should fetch a more recent version.

The same effect can be achieved by placing corresponding meta tags in your HTML document

PLAIN TEXT
HTML:
  1. <meta http-equiv="Expires" content="Tue, 03 Jul 1979 00:00:00 GMT" />
  2. <meta http-equiv="Pragma" content="no-cache" />

Where possible, place your cache control directives in the HTTP header, because some clients and proxies rely on your server's HTTP response to determine caching.

CODE:
  1. #Activate the rewrite engine if it isn't so already
  2. RewriteEngine on
  4. #intercept all HTTP requests to the site that do not have a 'www.' at the beginning of the Domain name
  5. #and then force a redirect to the same page address only this time, including the 'www.'
  6. RewriteCond %{HTTP_HOST} !^www\..* [NC]
  7. RewriteRule ^(.*) http://www.%{HTTP_HOST}/$1 [R=301]
  9. #The inverse of the above rule - intercept HTTP requests with a 'www.' at the start and redirect to the non-www version
  10. # Ensure that your serverName directive is set up to the non-www name of your domain
  11. RewriteCond %{HTTP_HOST} ^www\..* [NC]
