Question

In jQuery, how can I check that a selectbox contains a specific class or not? For example, in the below code snippet, I want to check whether the selectbox with id “customerIds” contains any option with class “C” or “D”.

<select id="customerIds" onchange="doOperation()">
    <option value="default"> Start..</option>
    <option value="1" class="A"> 1</option>
    <option value="2" class="B"> 2</option>
    <option value="3" class="C"> 3 </option>
</select>

Use hasClass() method: http://api.jquery.com/hasClass/

For example:

$("#customerIds").find("option").hasClass("A");
