Question

Can someone give me an example of using ajax to fill a dropdown using struts 2.0.6?

Answer 1

Use jquery on client side:

$.getJSON("/getDropDownlistValues", function(result) {
    var options = $("#options");
    //don't forget error handling!
    $.each(result, function(item) {
        options.append($("<option />").val(item.value).text(item.text);
    });
});

On server side write this key value strings into Servlet response type.
