这是我目前拥有的东西，不幸的是，我似乎无法弄清楚如何autoFill使用jQuery-UI …它曾经与直接的Autocomplete.js一起使用

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>

<script language="javascript" type="text/javascript">


    var thesource = "RegionsAutoComplete.axd?PID=3"
    $(function () {
        function log(message) {
            $("<div/>").text(message).prependTo("#log");
            $("#log").attr("scrollTop", 0);
        }

        $.expr[':'].textEquals = function (a, i, m) {
            return $(a).text().match("^" + m[3] + "$");
        };

        $("#regions").autocomplete({
            source: thesource,
            change: function (event, ui) {
                //if the value of the textbox does not match a suggestion, clear its value
                if ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0) {
                    $(this).val('');
                }
                else {
                    //THIS IS CURRENTLY NOT "LOGGING" THE "UI" DATA
                    //IF THE USER DOES NOT EXPLICITLY SELECT
                    //THE SUGGESTED TEXT
                    //PLEASE HELP!!!
                    log(ui.item ? ("Selected: " + ui.item.value + " aka " + ui.item.id) : "Nothing selected, input was " + this.value);
                }
            }
        }).live('keydown', function (e) {
            var keyCode = e.keyCode || e.which;
            //if TAB or RETURN is pressed and the text in the textbox does not match a suggestion, set the value of the textbox to the text of the first suggestion
            if ((keyCode == 9 || keyCode == 13) && ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0)) {
                $(this).val($(".ui-autocomplete li:visible:first").text());
            }
        });
    });


</script>

我在后端的JSON看起来像这样

[
    { "label": "Canada", "value": "Canada", "id": "1" },
    { "label": "United States", "value": "United States", "id": "2" },
]

我使用了这里的答案来使mustMatch正常工作，但是不幸的是，如果我在输入框中“跳格”，或者如果我完全键入单词而不是实际选择建议的文本，那么我会得到“没有选择”响应，而不是值和ID。

当您实际上没有选择字段时，有人知道如何从自动完成中提取ID吗？

基本上，我正在寻找的东西与Month (local):此处找到的示例相似：http :
//jquery.bassistance.de/autocomplete/demo/

但显然使用 jQuery-UI 而不是 jquery.autocomplete.js
