delete table row with javascript
Question by Craig
currently I have a table for information called episodes. The table has fields consisting of title, air date, episode number, and plot. I use javascript to clone the fields and also to delete them. My problem is the delete function deletes only the title, airdate, and episode number; however the plot box remains. The problem from what I can tell is that the plot is wrapped in a different <tr></tr>
tag. How do i get the delete function to delete both sets?
Here is the table
<table id="template" style="display: none">
<tr class="line">
<td width="50%">
<label><?php _e('Episode Title'); ?></label>
<p>
<input type="text" name="episode_title[]" id="episode_title[]" value="" class="title regular-text" style="width:100%;" />
</p>
</td>
<td width"10%">
<label><?php _e('Airdate'); ?></label>
<p>
<input type="text" name="episode_airdate[]" id="episode_airdate[]" value="" class="airdate regular-text" style="width:100%" />
</p>
</td>
<td width="10%">
<label><?php _e('Season:'); ?></label>
<p>
<?php
for($i=1; $i<=50; $i++)
$season_nums[]=$i;
echo '<select name="episode_season[]" select id="episode_season[]" class="season regular-text" style="100%">';
echo '<option value="">' . __("Season" ) . '</option>';
foreach($season_nums as $season_num){
$selected = '';
echo '<option value="' . $season_num . '" ' . $selected . '>' . $season_num . '</option>';
}
echo '</select>';
?>
</p>
</td>
<td width="10%">
<label><?php _e('Episode:'); ?></label>
<p>
<input type="text" name="episode_number[]" id="episode_number[]" value="" class="number regular-text" style="width: 100%" />
</p>
</td>
<td width="10%" class="commands">
<a rel="delete" class="button">-</a> <a rel="add" class="button">+</a>
</td>
</tr>
<tr class="line2">
<td width="100%">
<label><?php _e('Plot:'); ?></label>
<textarea name="episode_plot[]" id="episode_plot[]" class="plot regular-text"value="" cols="100%" rows="10" tabindex="4" ><?php echo $_POST['episode_season'] ?></textarea>
</td>
</tr>
Here is the JavaScript
// Delete the "-" button in first row
$('#attachments tr:first-child .commands a[rel="delete"]').remove();
}
function items_add()
{
obj = $('#template tr').clone().appendTo('#attachments');
lines++;
if (arguments.length > 0) {
options = arguments[0];
$('.title', obj).val( options.title );
$('.airdate', obj).val( options.airdate );
$('.season', obj).val( options.season );
$('.number', obj).val( options.number );
$('.plot', obj).val( options.plot );
}
}
$('#attachments').delegate('.commands a', 'click', function()
{
var action = $(this).attr('rel');
var confirm_delete = true;
// Add action
if ('add' == action) {
items_add();
}
// Delete action
if ('delete' == action) {
// La TR en la tabla
var oTr = $(this).parent().parent();
var episode_name = $('.title', oTr).val();
var episode_airdate = $('.airdate', oTr).val();
var episode_season = $('.season', oTr).val();
var episode_number = $('.number', oTr).val();
var episode_plot = $('.plot', oTr).val();
if (episode_name != '' || episode_number != '' || episode_plot != '') {
if ( !confirm('Are you sure you want to delete ' + episode_name + '?') ) {
confirm_delete = false;
}
}
if (confirm_delete) {
oTr.remove();
lines--;
}
}
});
$(document).ready(function()
{
items_init();
});
})(jQuery);
Your help will be greatly appreciated

Change this line
var oTr = $(this).parent().parent();
to
var oTr = $(this).closest("tr");
Then use oTr.remove()
