.display() and .conceal() functions malfunctioning

I'm in the process of creating a calendar system using the Codeigniter framework. My goal is to display a specific div every time a day cell in the calendar template is clicked.

These divs are generated through a PHP for loop and populated from the database in the following view file:

calendar_view.php


    <div class="cal_container">

<?php echo $calendar; ?>

<div class="day_expanded_container">

<?php for ($i = 1; $i<=31; $i++):?>

    <div class="day_expanded" id"<?php echo 'd'.$i;?>">

    <?php if (isset($calendar_info[$i])):?>

        <h2><?php echo $calendar_info[$i]['title'];?></h2>
        <p><?php echo $calendar_info[$i]['text']?></p>

    <?php else: ?>

        <h2>No Data for this Date</h2>
        <p>There is currently nothing planned for this Calendar date.</p>

    <?php endif; ?>

    </div>

<?php endfor;?>

</div>

</div>

Next, the following jQuery script is implemented:

scripts.js

$(document).ready(function(){

    var divs = $('div.day_expanded_container > div').get();
    var today = $(".today").attr("id");
    $(divs).hide().filter('#d' + today).show();

    $(".day").click(function() {

        var selected = $(this).attr("id");
        $(divs).hide().filter('#d' + selected).show();

    });

});

However upon page loading, all divs remain hidden and clicking does not reveal them at all.

All IDs appear correct and I've checked the CSS for potential conflicts, but I can't seem to find any issues. Could there be something obvious that I'm overlooking?

Thank you in advance!

Answer №1

There is a small mistake in your code:

id"<?php echo 'd'.$i;?>"

The correct syntax should be:

id="<?php echo 'd'.$i;?>"

Answer №2

Instead of using a complicated filter, it is easier to address the element directly if you have its ID that you want to hide. For instance, if the ID you need to hide is:

'#d' + selected

You can simply use this jQuery code to hide it:

$('#d' + selected).hide();

IDs must be unique in your page, making it unnecessary to scope them to a parent element. A global search for IDs may actually be faster as it utilizes the native getElementById function within jQuery supported by all browsers.

If, for some reason, your IDs are not unique on the page, you will need to resolve this issue before performing CSS selector operations reliably on them.
