Hiding empty inputs by parent row in jquery
I have the following HTML:
<table>
<tr class="row">
<td class="field">
<input type="text" />
</td>
<td class="field">
<input type="text" />
</td>
<td class="field">
<input type="text" />
</td>
</tr>
<tr>
...
...
</tr>
</table>
I want to be able to hide the <tr>
with the class="row"
but only when the input within the <td>
with the class="field"
is empty when the page loads.
I've tried this, but it doesn't work:
$('td.field:text[value=""]').parents('tr.row').hide();
However, for some reason, this DOES work:
$('td.field).parents('tr.row').hide();
(ie: it hides all of the rows with class="row"
)
Also, the following DOES work:
$('td.field:text[value=""]').开发者_高级运维val('test');
(ie: all empty inputs are populated with 'test' on page load)
I'm new to JQuery so I'm suspecting that I may have just misunderstood the way chaining works. can anyone give me any pointers? It semms like the two parts of what I am trying to do are correct when attempted separately, but don't work together as one.
I think it should be in this way:
$('td.field :text[value=""]').parents('tr.row').hide();
The reason: :text (input) is child from td.field. If you put td.field:text it's wrong because they are diferente selectors.
and why dont you go the oposite way - select the INPUT with empty value, and than go to its
parents().parents().hide()
first parents to get TD, the second one to get TR
