Issue with displaying jQuery class names accurately

I am implementing jquery.scrollablecombo.js for a dropdown menu using jQuery. However, when I include it in my HTML code, the class attribute is displayed as "classname" instead of "class." See the example below:

<div classname="searchBar cb_selectMain cb_down"></div>

As a result, the CSS styles are not being applied correctly.

Snippet of scrollablecombo.js code:

(function($) {

    $.fn.scrollablecombo2 = function(options) {
        // Function logic here...
    };

    $.fn.scrollablecombo = function(options) {
        // Function logic here...
    };

    $.fn.scrollablecombo1 = function(options) {
        // Function logic here...
    };
})(jQuery);

If anyone can provide assistance on this issue, it would be greatly appreciated.

Answer №1

The issue is found in the sections of your script that generate new elements:

var $wrapperElement = $("<div />", {
    "class": "searchBar cb_selectWrapper"
});

The object literal you provide to $() should be labeled by HTML attribute names, not DOM property names. className is a DOM property, while class is the corresponding HTML attribute. Your revised code should look like this:

var $wrapperElement = $("<div />", {
    "class": "searchBar cb_selectWrapper"
});

Answer №2

There is a clever workaround for this issue that involves minimal changes to the existing code:

Imagine you have the following scenario:

...

Instead of modifying each instance individually, consider utilizing jQuery in the following manner:

$("div").addClass($(this).attr('classname'));

By executing this snippet, the value from the attr classname will be copied into the class attribute as intended.

An alternate approach, albeit not entirely validated, could entail replacing all instances of className with class throughout the codebase.
