Target blank links with Jquery

Rodolfo Martinez — Sat, 08 Oct 2011 15:38:46 +0000

Sometimes I need just to update a site and the document type is in Strict mode, for me in the beggining I used to use target=blank on links, but the XHTML 1.0 in Strit mode don´t allow us to use this attribute.
So how to do a site with no warning and errors in the html without tagert=blank? Simple let´s take Jquery do it for us.

The example above I use the rel element, but you can use a class or a id if you want, rel element is more semantic.

Javascript

$('a[@rel$='external']').click(function(){
this.target = "_blank";
});

convert unixtime to timestamp

Rodolfo Martinez — Fri, 07 Oct 2011 15:12:20 +0000

This for me has always been an annoying thing, data is to be made of days, months and years and not a few numbers that have to be converted all the time.
I want to take a look at the database and say “son of a beautiful mother, he made the change and is now he´s saying that he did it three days ago.”
I hope you enjoy.

So there is the php version to convert

Normal date to UNIXTIME

So if you want other type of conversions, for example, just the day or without the time take a look at the php manual to see the many kind of uses

UNIXTIME for default time

Mysql version


mysql> SELECT UNIX_TIMESTAMP();
        -> 1196440210
mysql> SELECT UNIX_TIMESTAMP('2007-11-30 10:30:19');
        -> 1196440219

mysql> SELECT UNIX_TIMESTAMP('2005-03-27 03:00:00');
+---------------------------------------+
| UNIX_TIMESTAMP('2005-03-27 03:00:00') |
+---------------------------------------+
|                            1111885200 |
+---------------------------------------+
mysql> SELECT UNIX_TIMESTAMP('2005-03-27 02:00:00');
+---------------------------------------+
| UNIX_TIMESTAMP('2005-03-27 02:00:00') |
+---------------------------------------+
|                            1111885200 |

I´ve been working with Jquery for a loooong time, so I will share some experiences.
Above an example how to select all checkboxes with one single checkbox.
It´s a very simple example an then you could made a lot of modifications.

html



 Select All 
 item 1
 item 2
 item 3

$(".chkAll").click(function(){//remember that this will work in the element whith the class chkAll
if( $(this).is(':checked') ){
$(this).parent().parent().find(':checkbox').attr('checked', true);
}else{
$(this).parent().parent().find(':checkbox').attr('checked', false);
}
})
