JQuery Dropdown Select Event

Is there a specific event for when a user selects an item in a dropdown box? I am creating a fairly large form that uses multiple dropdown boxes. On load all but the first are disa

Solution 1:

Try Below code:

<select id="drop1">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
<select id="drop2"></select>

Jquery

$(document).ready(function(){
$("#drop2").attr("disabled", true);
$("#drop1").change(function(){
    $("#drop2").attr("disabled", false);
    //Put your ajax code here and bind like below code
    $("#drop2").append(new Option("option text", "value"));
    $("#drop2").append(new Option("xxx","1"));        
});
});
