[JavaScript] On I care about older browsers without JS

2007-10-31T14:59:33-07:00

No sir. This was client side JS sent to us via an ad server. The entirity of their code is like that. They declare a variable and set a value to it and the next line they redeclare it with a different value. Everything about their ad server is random and it boggled my mind so much I thought I'd share.

2007-10-30T22:30:23-07:00

I found this great piece of code from an ad server and thought to myself that I should learn to make my own JS legacy compliant. Can anyone please tell me if they know a better way to do this? Thanks in advance.

document.write ('<noscript>\n');
document.write (imageClick);
document.write ("</noscript>");

[JavaScript] On Curry

2007-10-30T15:41:28-07:00

I would use bindAsEventListener here so that you can use the event.

# W/ Prototype and W/out currying
$(imgID).observe("mouseover", 
  function(event) {
    this.mouseOver(i)
}.bindAsEventListener(this));

[JavaScript] On Random URL

2007-10-30T15:32:03-07:00

I much prefer Fu86's refactor but honestly this kind of stuff should not be done in Javascript.

[Ruby] Is This String Postal?

2007-10-30T15:29:16-07:00

We've had the debate over wether it was a good idea or not to do this.

class String 
  def postal?  
    self.match(/[a-zA-Z]{1}\d{1}[a-zA-Z]{1}([\x20-])*\d{1}[a-zA-Z]{1}\d{1}/) ? true : false
  end
end

[Ruby] On Iffy

2007-10-11T19:55:00-07:00

in the middle of all of this I had to add another else... a coworker mentionned this example

p = Proc.new { |en, fr| lang.to_s == "en" ? en : fr }
breaker = case location_type
  when 'point'
    p.call('near', 'proximite')
  when 'street'
    p.call('on', 'sur')
  else
    p.call('in', 'dans')
end

[Ruby] Iffy

2007-10-11T19:15:38-07:00

With all the magic surrounding ruby I can't help but think that there are shorter and more readable ways to do this.

if self.location_type.to_s == 'point'
  breaker = self.lang == 'fr' ? 'proximite' : 'near'
 else  
  breaker = self.lang == 'fr' ? 'dans' : 'in'
end

[JavaScript] On Is this year a leap year?

2007-09-21T08:05:16-07:00

Indeed we could remove one of the conditions. I replaced the condition with an integer value test instead, because JS automatically assumes that any value other than 0 is true. Unfortunately it means more parenthesis but it still makes the code shorter.

Can we find any other ways of making this shorter? :-D

PS: you should add a way to add more than one code snippet so you can show two pieces of code that work together. I'd love to show the test portion of this code in the same thread.

Object.extend(Date.prototype, {
  isLeap: function(){
    var year = this.getFullYear();
    return !(year % 4) && !!(year % 100) || !(year % 400);
  }
});

[JavaScript] Is this year a leap year?

2007-09-21T07:16:53-07:00

I'm pretty sure we can figure out a shorter and more elegant way to do this :-D

Object.extend(Date.prototype, {
  isLeap: function(){
    var year = this.getFullYear();
    return (year % 4 == 0 && year % 100 != 0) || (year % 100 == 0 && year % 400 == 0);
  }
});

[Ruby] On Ruby simple loop

2007-09-18T10:26:43-07:00

definitely less keystrokes

for i in (1..10)
  puts i
end

[JavaScript] Hello World

2007-09-17T13:09:40-07:00

This is simply to test out the Javascript colors :-D

String.prototype.hello = function(){
  alert('hello world!');
}

Object.extend(String, {
  hello: function(){
    document.write('hello world');
  });
