Question

In my web page, I have a table of dates (my date format is dd-mm-yyyy)

<tr>
    <td>05-03-2012</td>
    <td name="expiration">09-07-2012</td>
    <td>08-10-2012</td>
 <tr>

What I want is to put in red color expiration dates when their value is > current date, using Jquery.

So, I think I am going to use something like :

<script>
//don't know how to retrieve the expiration date and check if it is after the
//current date 

$('td[name=expiration]').css({"color":"red"});
</script>

Answer 1

Prefer to use a class instead of a name so your selector is more efficient:

<tr>
    <td>05-03-2012</td>
    <td class="expiration-date">09-07-2012</td>
    <td>08-10-2012</td>
</tr>

var now = new Date;
$('.expiration-date').text(function (i, v) {
    if (now < new Date(v)) {
        $(this).addClass('unexpired');
    }
});
