Issue with jQuery select box (roblaplaca) and its custom scroll bar functionality not functioning as expected

Recently, I implemented the custom select box script from . This script allows for two select boxes, where the second one updates dynamically using AJAX when there is a change in the first select box. Below is a sample of the HTML code:

<option>One</option>
<option>Two</option>
<option>Three</option>

To update my select box after an AJAX success, I utilized the sync() method. While the content does get updated successfully, I encountered an issue where the scroll bar disappears.

I delved into the selectbox.js file and noticed that the sync() method invokes the _setupScrollbar() function after updating the content. However, despite this call, the scroll bar fails to appear. Can anyone provide assistance with resolving this problem?

Answer №1

When working with your SelectBox.js file, make sure to make the following modifications:

(1) Locate the function _setupScrollbar() and insert the code autoReinitialise: true. The updated code should appear as follows:

self.scrollpane = $dl.jScrollPane($.extend({
    contentWidth: 200,
    autoReinitialise: true
}, cfg.scrollOptions));

(2) Find the function this.sync = function() and make the following changes:

this.sync = function() {
    $options = cfg.selectbox.find("option");
    //$dl.html(_renderOptions());
    $jpane = $customSelect.find("div.jspPane");

    if($jpane.length == 1) // check if selectbox has a scrollbar
    {
       $jpane.html(_renderOptions()); //Inject HTML into selectbox with scrollbar
    }
    else
    {
       $dl.html(_renderOptions()); //Inject HTML into selectbox without scrollbar
    }

    _bindHover();
    _setupScrollbar();
};

The scrollbar may not be functioning due to jsPane being replaced with new content. Therefore, I have made adjustments in the sync() function as shown below:

// $dl.html(_renderOptions());
$jpane = $customSelect.find("div.jspPane");
if($jpane.length == 1) // need to check if selectbox having scroll bar?
{
   $jpane.html(_renderOptions()); //HTML injected to selectbox having scrollbar
}
else
{
   $dl.html(_renderOptions()); //else HTML injected to selectbox not having scrollbar
}

These changes should help resolve the issue you are facing.

Answer №2

I made some changes to @rajnikanth's code for customizing a selectbox without a scroll bar.

this.update = function() {
    $optionsList = cfg.selectbox.find("option");
    //$dl.html(_renderOptions());
    $scrollPane = $customSelect.find("div.scrollPane");

    if($scrollPane.length == 1) // check if selectbox has a scroll bar
    {
       $scrollPane.html(_renderOptions()); // Inject HTML for selectbox with scrollbar
    }
    else
    {
       $dl.html(_renderOptions()); // Inject HTML for selectbox without scrollbar
    }

    _bindHover();
    _configureScrollbar();
};
