AJAX文本字段自动完成，选中后，如何更改组合框的值？

I don't really know AJAX, I'm only using a bit of its feature in my project. I used its autocomplete feature in a textfield, which connects to a mysql database. Now I want it so that when a person is selected, his/her corresponding rank (which should also be acquired the database) will automatically be the value of the combobox (something like this)...

我真的不知道AJAX，我只是在我的项目中使用了它的一些功能。我在textfield中使用了自动完成功能，它连接到mysql数据库。现在我想要它，以便当一个人被选中时，他/她的相应等级（也应该被获取数据库）将自动成为组合框的值（类似这样）...

This tutorial applies a value after select to a text field and the combobox.

本教程将select之后的值应用于文本字段和组合框。

Be sure to check the demo:

一定要查看演示：

$(function() {

        $('#abbrev').val("");

        $("#state").autocomplete({
            source: "states.php",
            minLength: 2,
            select: function(event, ui) {
                $('#state_id').val(ui.item.id);
                $('#abbrev').val(ui.item.abbrev);
            }
        });

        $("#state_abbrev").autocomplete({
            source: "states_abbrev.php",
            minLength: 2
        });
    });
