jQuery的自动完成多输出 [英] jQuery AutoComplete multiple Output
问题描述
我使用jQuery自动完成获取基于输入的值从数据库中的结果。然后,用户会点击搜索按钮来告诉页面来搜索特定条目的详细信息。
我想获得2个值,在名称和标题即可。我只是想显示的名称给用户,而页面使用的标题作为搜索条件。
例如:当一个人类型的汽车后,结果将显示 Vehicle1,Vehicle2
列表中的结果
当用户点击 Vehicle1
,一个隐框将与在标题后,这将是自行车$问题C $ C>,以及诸如与
Vehicle2
,这将发出车
。
我可以在名称在文本框中显示正常,但我不能为我的生活(2天后搜索的)绑定在标题以一个隐藏的框。

这些修改到你的JavaScript应该做的伎俩:

这里的假设是,选择器返回到底是哪我们正在处理的元件,如果不是他们需要进行调整。
I am using jQuery AutoComplete to fetch results from a DataBase based on the value inputted. The user will then click a search button to tell the page to search for that specific entries details.
I want to get 2 values, the Name and Title. I only want to display the Name to the user, while the page uses the Title as a search criteria.
eg: When a person types in Vehicle, the result will display Vehicle1, Vehicle2
in a list.
When the user clicks on Vehicle1
, a hidden box will be issues with the Title, which would be Bike
, and such as with Vehicle2
, which will issue the hidden box with Car
.
I can get the Name to show in the text box properly, but I cannot for the life of me (And after 2 days of searching) bind the Title to a hidden box.
JavaScript:

<script type="text/javascript" src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script>

Those modifications to your JavaScript should do the trick:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript" src="http://code.jquery.com/ui/1.9.0/jquery-ui.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('input[name$="tbAuto"]').autocomplete({
source: function (request, response) {
$.ajax({
url: "AutoComplete.asmx/FetchEmailList",
data: "{ 'prefix': '" + request.term + "' }",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response(data.d);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2,
focus: function(event, ui) {
$('input[name$="tbAuto"]').val(ui.item.Name);
return false;
},
select: function(event, ui) {
$('input[name$="tbAuto"]').val(ui.item.Name);
$('input[name$="tbHidden"]').val(ui.item.Title);
return false;
}
}).data('autocomplete')._renderItem = function(ul, item) {
return $('<li>').data('item.autocomplete', item).append('<a>' + item.Name + '</a>').appendTo(ul);
};
});
</script>
The assumption here is that the selectors returns exactly the element which we are working on, if not they need to be adjusted.
