Javascript Question

Add a row on top of table generated by javascript

I made a mis calculation in a table structure. The code beneath is for a lotto game (a known piece of code I think ;))

Is there a way to add a row on top of the table filled with a numbers? I really don't know how to do this.

Answer

You can also do that using insertBefore:

$('<tr><td>Stuff</td></tr>').insertBefore('table > tbody > tr:first');

or with before:

$('table > tbody > tr:first').before('<tr><td>Stuff</td></tr>');

or with prependTo:

$("<tr><td>prependTo</td></tr>").prependTo("table > tbody");
