内容图文
我一定是个白痴.我正在使用Typeahead.js插件.我正在尝试使用自定义模板来提出建议.当我的自定义模板出现时,我不能使用箭头键来实际选择一个项目.如果我将鼠标悬停在某个项目上,则所选内容也不会突出显示.我认为这可能只是样式问题.但是,如果出现3条建议,并且我单击两次向下箭头,然后输入,则我选择的选项不会出现在文本框中.或者,如果我用鼠标选择一个选项,则该选项不会出现在框中.
我究竟做错了什么？目前,我有以下内容：
var suggestions = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
queryTokenizer: Bloodhound.tokenizers.whitespace,
remote: {
url: '/api/suggests?querytext=%QUERY',
filter: function(results) {
return $.map(results.Results, function(suggestion) {
return suggestion;
});
}
});
suggestions.initialize();
$(document).ready(function() {
$('input.typeahead').typeahead(
{ minLength: 3 },
{
name: 'suggestions',
source: suggestions.ttAdapter(),
templates: {
suggestion: function(data) {
var str = '';
if (data.Type === 'Customer') {
str += '<i class="icon-1"></i>';
} else if (data.Type === 'Product') {
str += '<i class="icon-2"></i>';
}
str += '<div>' + data.Name + '</div>';
return str;
}
}
}
);
});
建议弹出.结果来自以下JSON：
{
"Results":[
{
"Type":"Customer",
"Id":5,
"Name":"Bill",
"LastUpdated":"01-01-2015"
},
{
"Type":"Customer",
"Id":135,
"Name":"Billows",
"LastUpdated":"01-02-2015",
},
{
"Type":"Product",
"Id":241,
"Name":"Bill Check",
"LastUpdate":"01-04-2015"
}
],
"TotalResults":3,
"TotalCustomers":2,
"TotalProducts":1
}
我如何a)当用户将鼠标悬停在某个项目上或使用箭头键将其高亮显示在项目上时b)选择建议后,在输入框中输入所选项目的名称值？
谢谢！
解决方法:
尝试
$(function () {
var suggestions = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
queryTokenizer: Bloodhound.tokenizers.whitespace,

return $.map(results.Results, function(suggestion) {
return {value:suggestion.Name, suggest:suggestion};
});
}
});
suggestions.initialize();
$("#bloodhound .typeahead").typeahead({
