What to do if Firebug console is not available

Sometimes in our JavaScript code we use bulit-in console to view information, errors, etc. But when we close the Firebug then we see the JS errors. Why? Because there is no object window.console. So, what to do? Just create console object and create empty object for all console methods.

My code, which I use:

/**
 * Firebug console
 * If not available then add empty method
 */

var isFirebug = false;

if(typeof window.console != 'undefined')
{
    for (var obj in window.console)
    {
        if (typeof window.console[obj] != 'u[......]

JavaScript and convert HTML characters entities back to regular text

After some research I found the simple solution to convert HTML characters entities back to regular text using JavaScript. The code is simple and fast.

var decodeEntities = function( s )
{
	var str, temp = document.createElement('p');
	temp.innerHTML = s;
	str = temp.textContent || temp.innerText;
	temp = null;
	return str;
};

JavaScript and get date from timestamp

Have you ever tried to create date from timestamp using JavaScript? After some testing code I found the solution. This is what i use:

var getDateFromTimestamp = function( t )
{
    var a = new Date(t);
    
    a =
    {
        day : a.getDate(),
        month : a.getMonth() + 1,
        year :  String( a.getFullYear() ),
        hours : a.getHours(),
        minutes : a.getMinutes()
    };
	
	if( a.month < 10 )
	{
		a.month = '0' + a.month;
	}
	
	if( a.minutes < 10 )
	{
		a.minutes = '0' + a.minutes;
	}
    
    var fulldate = [a.day, a.month, a.year].join('.'),
        time = [a.hours, a.minutes].join(':');
    
    return ({
        fulldate : fulldate,
        time : time
    });
};

Let authors put line breaks (newlines) in tooltips (title attribute)

It’s seems that in Firefox 12 developers will be able to use breaks (newlines) in tooltips (title attribute). Finally.

At this moment there is no way to use new line code to break a line text in title attribute. Of course, there is some tricks to change title to your_attribute and then styling it, but unfortunately this options is poor accessibility. Screen readers may have problem with non-standard attributes. As I know.
