            }
            $("#dropdown").val(curval);
        }
    });

Answer 1

您在函数末尾说val（curval），但函数参数名为currval，带有两个R。

Answer 2

This worked!

function getAjaxFunction(thisval, curval) { 
    $.ajax({ 
        type: "POST", 
        url: "lookup.do?param="+thisval, 
        cache: false, 
        success: function(data) { 
        var values = data; 
        var vals   = values.split(";"); 
            $("#dropdown").find("option").remove().end(); 
            for (var i = 0; i < vals.length; i++) { 
                var parts = vals[i].split(":"); 
                $("#dropdown").append($('<option />').val(parts[0]).text(parts[1])); 
            } 
            try {
                  $("#dropdown").val(curval);
            } catch(ex) {
                  setTimeout("$('#dropdown').val('"+curval+"')",1);
            }
        } 
    }); 
}
