Question

我遇到了一个我无法解决的问题。我在输入上使用jQuery的autocomplete插件。 HTML看起来像这样：

<tr id="row_house" class="no-display">
        <td class="col_num">4</td>
        <td class="col_label">House Number</td>
        <td class="col_data">
            <input type="text" title="House Number" name="house" id="house"/>
            <button class="pretty_button ui-state-default ui-corner-all button-finish">Get house info</button>
        </td>
    </tr>

我确信这是唯一的id="house"字段。在此之前的其他字段与自动完成工作正常，并且它基本上是相同的算法（其他变量，其他数据，其他调用）。那么为什么它不能像它应该使用以下init一样工作。代码：

$("#house").autocomplete(["1/4","6","6/1","6/4","8","8/1","8/5","10","10/1","10/3","10/4","12","12/1","12/5","12/6","14","14/1","15","15/1","15/2","15/4","15/5","16","16/1","16/2","16/21","16/2B","16/3","16/4","17","17/1","17/2","17/4","17/5","17/6","17/7","17/8","18","18/1","18/2","18/3","18/5","18/95","19","19/1","19/2","19/3","19/4","19/5","19/6","19/7","19/8","20","20/1","20/2","20/3","20/4","21","21/1","21/2","21/3","21/4","22","22/9","23","23/2","23/4","24","24/1","24/2","24/3","24/A","25","25/1","25/10","25/2","25/4","25/5","25/6","25/7","25/8","25/9","26","26/1","26/6","27","27/2","28","28/1","29","29/2","29/3","29/4","30","30/1","30/2","30/3","31","31/1","31/3","32/A","33","34","34/1","34/11","34/2","34/3","35","35/1","35/2","35/4","36","36/1","36/A","37","37/1","37/2","38","38/1","38/2","39/1","39/2","39/3","39/4","40","40/1","41","41/2","42","43","44","45","45/1","45/10","45/11","45/12","45/13","45/14","45/15","45/16","45/17","45/2","45/3","45/6","45/7","45/8","45/9","46","47","47/2","49","49/1","50","51","51/1","51/2","52","53","54","55/7","66","109","122","190/8","412"], {minChars:1, mustMatch:true}).result(function(event, result, formatted) {
                var found=false;
                for(var index=0; index<HChouses.length; index++) //HChouses is the same array used for init, but each entry is paired with a database ID.
                    if(HChouses[index][0]==result)
                    {
                        found=true;
                        HChouseId=HChouses[index][1];
                        $("#row_house .button-finish").click(function() {  
                            QueryServer("HouseConnect","FillData",true,HChouseId); //this performs an AJAX request
                        });
                        break;
                    }
                if(!found)
                    $("#row_house .button-finish").unbind("click");
            });

每次我开始输入（比如我按下“1”按钮），文本就会出现并立即被删除。在重复按下之后我很少得到清单（虽然比它应该短得多）alt text http://www.freeimagehosting.net/uploads/de3892134d.jpg

但如果在那之后我按下第二个数字，整个事情就会再次消失。附：我使用Firefox 3.6.3进行开发。

看起来你要问的是有一个使用自动完成的文本框，当选择一个值时，它会执行一些函数（此处QueryServer）和所选值的id。实际上，这是html <select>的动态ajaxy版本。如果那是错的，请纠正我。

我最近使用jQueryUI自动完成功能做了类似的事情。你在评论中提到你没有运气试过这个，但我认为你对使用这两个库的解决方案感兴趣。我就是这样做的：

$("house").autocomplete({
    source: [{'id': 1, 'value': '10/1'}, {'id': 2, 'value': '10/3'}, {'id': 3, 'value': '10/4'}, ....
    minLength: 1,
    select: function(event, ui) {
        //input will auto-populate with "value" part
        $("#row_house .button-finish").click(function() {  
            QueryServer("HouseConnect","FillData",true,ui.item.id);                           
        });
    },
    //this next function is a hack to replicate the "mustMatch" functionality of the bassistance autocomplete plugin
    change: function (event, ui) {
        var source = $(this).val();
        var found = $('.ui-autocomplete li').text().search(source);
        if(found < 0) { //no match!
           $(this).val('');
           $("#row_house .button-finish").unbind("click");
        }            
    }
});

您可能希望在其他位置声明source值以使其更整洁。
