我正在使用Typeahead来显示项目数据库和商店数据库中的提示。当我只显示项目的提示时,它显示正常,当我只显示商店的工作也很好,但当我尝试显示混合结果时,它只显示默认的空信息。检查AJAX答案,在三种情况下看起来很好,所以它必须在客户端。
JS代码是这样的:
var items = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('name'),
queryTokenizer: Bloodhound.tokenizers.whitespace,
remote: {
url: '/ajax/pesquisar/',
prepare: function(query, settings) {
tokens = query.trim().split(' ');
return '/ajax/pesquisar/' + tokens.join('/') + '/';
}
}
});
$('input.typeahead').typeahead({
hint: true,
highlight: true,
minLength: 1
},
{
name: 'items',
display: 'name',
source: items,
templates: {
empty: [
'<div class="empty-message">',
'Nenhum item relacionado',
'</div>'
].join('\n'),
suggestion: Handlebars.compile('<a href="{{url}}"><div class="suggestion"><div class="icone" style="background-image:url({{img}});"></div>{{name}}</div></a>')
}
});
针对项目的AJAX响应(正确显示):
[
{
"id":"00007531",
"url":"\/higiene-e-limpeza\/cabelos\/condicionador-seda-cachos-comportados-e-definidos-350ml\/",
"name":"Condicionador Seda Cachos Comportados e Definidos 350mL",
"img":"\/img\/produtos\/7891037000315_I.png"
},
{
"id":"00007641",
"url":"\/higiene-e-limpeza\/cabelos\/shampoo-seda-cachos-comportados-e-definidos-350ml\/",
"name":"Shampoo Seda Cachos Comportados e Definidos 350mL",
"img":"\/img\/produtos\/7891037000308_I.png"
}
]
仅限商店(工作正常):
[
{
"id":"00000001",
"url":"\/nidobox\/montese\/",
"name":"Supermercado Nidobox - Montese",
"img":"\/img\/supermercados\/nidobox_i.jpg"
},
{
"id":"00000002",
"url":"\/nidobox\/damas\/",
"name":"Supermercado Nidobox - Damas",
"img":"\/img\/supermercados\/nidobox_i.jpg"
},
{
"id":"00000003",
"url":"\/nidobox\/aeroporto\/",
"name":"Supermercado Nidobox - Aeroporto",
"img":"\/img\/supermercados\/nidobox_i.jpg"
}
]
混合两个结果时(显示默认的空信息):
[
{
"id":"7531",
"url":"\/higiene-e-limpeza\/cabelos\/condicionador-seda-cachos-comportados-e-definidos-350ml\/",
"name":"Condicionador Seda Cachos Comportados e Definidos 350mL",
"img":"\/img\/produtos\/7891037000315_I.png"
},
{
"id":"7641",
"url":"\/higiene-e-limpeza\/cabelos\/shampoo-seda-cachos-comportados-e-definidos-350ml\/",
"name":"Shampoo Seda Cachos Comportados e Definidos 350mL",
"img":"\/img\/produtos\/7891037000308_I.png"
},
{
"id":"1",
"url":"\/nidobox\/montese\/",
"name":"Supermercado Nidobox - Montese",
"img":"\/img\/supermercados\/nidobox_i.jpg"
},
{
"id":"2",
"url":"\/nidobox\/damas\/",
"name":"Supermercado Nidobox - Damas",
"img":"\/img\/supermercados\/nidobox_i.jpg"
},
{
"id":"3",
"url":"\/nidobox\/aeroporto\/",
"name":"Supermercado Nidobox - Aeroporto",
"img":"\/img\/supermercados\/nidobox_i.jpg"
}
]
使用的搜索字符串是“nido”。 。 我看到的唯一区别是ID中的尾随零。将这些ID转换为int并仍然存在相同的问题。谁能看到我错过的东西?
由于
编辑:将结果数组切换为服务器端的4个提示,现在是typeahead而不是显示空消息显示第一个提示而不是其他3个提示。

发现问题。这是typeahead.bundle.js(v 0.11.1)中的一个错误。它会在追加它们之前计算渲染提示的数量,因此如果提示数量等于限制,它将附加一个空数组。
为了防止这种情况,我只是改变了第1723和1724行,所以它看起来像这样:
that._append(query, suggestions.slice(0, that.limit - rendered));
rendered += suggestions.length;
已经在typeahead的github中报告了这个问题。

@Luciano Garcia Bes - 要完成你的anwser,请在下面发布所需的所有更改:
你有必要切换这些行,但我也需要删除- rendered
。
所以最后它sholud看起来像这样(整个功能):
function async(suggestions) {
suggestions = suggestions || [];
if (!canceled && rendered < that.limit) {
that.cancel = $.noop;
that._append(query, suggestions.slice(0, that.limit));
rendered += suggestions.length;
that.async && that.trigger("asyncReceived", query);
}
}

如果您使用托管的CDN版本,解决此问题的另一个选项是在启动时设置limit:'Infinity'
:
$(".input-search").typeahead({
hint: true,
highlight: true,
minLength: 2,
}, {
limit:'Infinity',
source: engine,
});
然后限制服务器上的结果
