Question

my first question. Also my english is far form being something I can describe as good, so please be forgiving (don’t know better word :)).

I am using php to generate table rows with diffrent style.

if ($n % 2 == 0)
    $tr_class = ' class="package_' . $p->package_id . ' alt"';
else {
    $tr_class = ' class="package_' . $p->package_id . '"';
}

<tr<?php echo $tr_class ?>

I want to select input field in fifth cell in each row that has class package_{number here} and add some styles to it.
To do so, I use that statement:

$('tr.package_' + package_errors_ids[i] + ' td:nth-child(5) input[type=text]').css('border', '1px solid red');

But second class (.alt) does not allow me to do this.
I don’t know how to modify that statement do achieve this.
Will you help? 🙂

I forgot to write it. It works but not everytime. Package_errors_ids is array containing numbers I use to create unique IDs for distinguish for user invalid packages. When 2 rows are invalid (one has .alt class), both are affected by this code css('border', '1px solid red');. But when one is valid, non of these rows are affected.

EDIT:
I’ve simplified my mixed js and php code in order to generate code without using JavaScript array

After this simplification and clearing my webbrowser cache, it works properly! Thank you all for your input. Here’s the code (if jsfindle.net erase it):

<script type="text/javascript">
$(document).ready(function() {
<?php
$count = count($this->package_errors_ids);
if ($count > 0)
{
    for ($i = 0; $i < $count; $i++)
    {
        echo "$('tr.package_" .
            (int) $this->package_errors_ids[$i] .
            " td:nth-child(5) input[type=\"text\"]').css('border', '1px solid red');\n";
    }
}
?>
});
</script>

I’m looking at this:

// in PHP
$('tr.package_' + package_errors_ids[i] + ' td:nth-child(5) input[type=text]')

That will generate something like this, I assume:

// after PHP
$('tr.package_1 td:nth-child(5) input[type=text]')

That won’t have any problems at all in selecting a <tr class="package_1 alt">. No trouble at all. Assuming your HTML is getting generated correctly, that means you’re doing something else wrong. And I’m going to assume that it’s this part:

input[type=text]

Try changing that to

input[type="text"]
