There are dates in the first column of the table:

<table> <tr> <td>01.12.2013 21:08:52</td> <td>...</td> </tr> <tr> <td>19.10.2014 1:13:12</td> <td>...</td> </tr> <tr> <td>19.10.2014 1:53:12</td> <td>...</td> </tr> </table>

It is necessary to show only the last by date (dmg, without comparing time) lines.

Update

I am not a student and the task is not educational, everything is for understanding and comes down to the practice of working with parsing and date on JS.

 $('table > tbody > tr > td:nth-child(1)').each(function() { if($(this).text() != last){ $(this).closest("tr").hide(); } });

How to parse dates optimally and compare?

It is necessary to break the date into components, and collect the Date object.

 19.10.2014 1:53:12

First, the space can be divided into an array of two elements: the date and time. Time is ignored, and the components of the date are already broken by points:

 .split(" ")[0].split(".")

This will give an array of three elements: day, month, year. They can be fed into the constructor of the Date object :

 new Date( parts[2], parts[1], parts[0])

From it, you can take the number of microseconds since the beginning of the unix era (integer) using the getTime() method.

It is necessary to run through all the <tr> rows of the table once, take the first <td> in them and pull that timestamp out of it, collecting unique values ​​in the array. Then sort it and pick up the highest value - the freshest day.

Now this timestamp must be converted to a date string in your format, adding "0" before single-digit dates and months, and get a sample string like "10/19/2014".

Having run through all the lines again, hide those in which the date (after splitting again by the space) is not equal to the sample.
