listValue="menuItemName" headerValue="--MenuItems--"

cssClass="selectbox_bg2" id="select" />

Can anyone please provide an example..

There is no difference in how you apply onchange or any other javascript event handler to struts tag as compared to regular HTML tags. Struts2 select Tag Ref

<s:select name="menuItem" list="menuItems" listKey="menuItemID"

listValue="menuItemName" headerValue="--MenuItems--"

cssClass="selectbox_bg2" id="select" onchange="handleChange(this.value)"/>

JavaScript

function handleChange(value){
  window.location="callMyAction?ValueToSubmit="+value; //or you can submit a form from here or make an ajax call
}

Or if you are using jquery then

$("#select").change(function(e){
    var value = $(this).val();
    //submit a form or make ajax call or use window.location
});
