jquery ajax call from select box

Question

How to make ajax call from onchange event of select box using jquery? If anyone has a sample, please post the code.

Answer 1

the below code is based on spring mvc architecture,

$('#selectbox1').change(function() {
    var data = "";
    $.ajax({
        type:"GET",
        url : "controller mapping",
        data : "selectbox1_selectedvalue="+$(this).val(),
        async: false,
        success : function(response) {
            data = response;
            return response;
        },
        error: function() {
            alert('Error occured');
        }
    });
    var string = data.message.split(",");
    var array = string.filter(function(e){return e;});
    var select = $('selectbox2');
    select.empty();
    $.each(array, function(index, value) {          
        select.append(
                $('').val(value).html(value)
            );
    });
        $('#selectbox2').show();
});

inside the html, i use like below to display the selectbox2 values,

    
        value1value2
    
    

in the selectbox2, values are loaded from a controller using ajax call, in controller i return like below,

    List listvalues = listService.retrieveAll(searchTerm); // searchTerm is a selected value from selectbox1
String dummy = "";
for(int i=0; i
