The dropdown button becomes unresponsive when attempting to navigate within it using ajax requests

Hello fellow members of the StackOverFlow community,

I recently implemented a Bootstrap 5 dropdown button to fetch tabs from the backend using AJAX. Everything was functioning correctly until I encountered an issue where, upon clicking a button within one of these tabs, the dropdown remained visible along with the data retrieved through AJAX. Additionally, a new request was being made ensuring that the data persisted. However, when attempting to open the dropdown again, it failed to do so.

Below is the code snippet used:

<li class="dropdownListMenu dropdown">
    <span aria-expanded="false" data-bs-toggle="dropdown" aria-haspopup="true" 
        class="active color-white pointer" data-bs-toggle="tab"
        onclick='<?php echo "get__data(" . $id . ")"; ?>'>
        <i class="fa fa-folder  tx-29"></i> 
        <?php echo $value['name']; ?>
        <i class="fas fa-caret-down ms-1"></i>
    </span>
    <div class = "dropdown-menu tx-13" id = "get_data_dropdown_<?php echo $_id; ?>">
    </div>
</li>

We utilized a JavaScript function to trigger backend communication via AJAX:

function get_data(id) {
    $.post("ajax/get_data.php", {id: id,}, function (data) {
        $("#results").html(data);
    });
}

The data returned from the AJAX call consists of a list generated by a foreach loop with links:

<a class="dropdown-item" onclick="get_classification(
    <?php echo $tbl_level_id; ?>,
    <?php echo $tbl_org_id; ?>,
    <?php echo $tbl_classin_id; ?>,
    <i class="fa fa-info-circle"></i> 
    <?php echo $value['name']; ?>
</a>

Upon accessing a link within this data, it gets appended to an empty div as follows:

<div id="results"> </div>

Subsequently, any further interactions with the links/buttons within the data result in the dropdown and its contents persisting but failing to work properly.

I trust this explanation clarifies the issue at hand.

Answer №1

After some investigation, I was able to identify the solution.

The root cause of the issue was a function that was originally implemented to address a specific problem. However, over time, this function stopped working effectively and was no longer necessary, so I decided to remove it.

<script>
    $(function () {
            //This updated function now resolves the dropdown button not opening issue on new pages.
            $('li>[data-bs-toggle="dropdown"]').each(function () {
                $(this).click(function () {
                    if (!$(this).hasClass("show") && $(this).attr("aria-expanded") === "false") {
                        $(this).next().addClass("show");
                        $(this).attr("aria-expanded", "true");
                        $(this).addClass("show");
                    } else {
                        $(this).next().removeClass("show");
                        $(this).attr("aria-expanded", "false");
                        $(this).removeClass("show");
                    }
                })
            })
        }
    )
</script>
