font-face and aborted request(s)

By default at least IE up to 9 8 (not tested on IE10 IE 9 and 10 doesn’t block loading content and they use local fonts, if available) blocks loading page until fonts are not downloaded. Moving fonts for font-face to separate subdomain (eg. means that page loading will not be blocked by loading fonts from font-face.

Detect browser cookie third party support using feature detection

So, you want to detect browser cookie third party support.

What is third-party cookies

Some browsers (from specific versions), like Firefox and Safari, have this option disabled by default. However, see page “How to enable third-party cookies in your web browser” t[……]

Wamp, error PHP Startup: Unable to load dynamic library ‘c:/wamp/bin/php/php5.3.13/ext/php_intl.dll’

Tried to run internationalization in WAMP using php_intl module, but got error Unable to load dynamic library ‘c:/wamp/bin/php/php5.3.13/ext/php_intl.dll’. This makes me headache. It happens because Apache can’t find the icu*.dll files. There is at least 3 solutions:

  • One solution is to add “C:\wamp\bin\php\php5.3.9” (or similar directory) to your system PATH.
  • The other solution is to copy the icu*.dll files to your apache’s bin directory.
  • A third option is to copy the icu*.dll files to your Windows system directory (system32 or SysWOW64)[……]

JavaScript, split and non-breaking space

I created and added pre element with contentEditable attribute. I inserted some text with non-breaking space and tried to get text and split using simple txt.split(/\s/), where txt represent string from pre element. Unfortunately, this split doesn’t work well in IE7 and return wrong splitted data in array when string contains non-breaking spaces.

I solved this problem by using little trick:

var temp = doc.createElement('div'),

temp.innerHTML = txt;
str = temp.innerText || temp.textContent || temp.text;
temp = null;

Get value from URL param

Well, this time will be shortly as always. I wanted to get value from some param in URL. After some research this could be done by this code (I use it):

 * Function getValueFromURLparam
 * Extracting Querystring key/value pairs

var getValueFromURLparam = function(name, url)
	name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
	var regexS = "[\\?&]"+name+"=([^&#]*)";
	var regex = new RegExp( regexS );
	var results = regex.exec(url);
	return (results === null) ? "" : results[1];
