I'm using https://github.com/bassjobsen/Bootstrap-3-Typeahead
My code:
<input type="text" class="typeahead" autocomplete="off">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('.typeahead').typeahead({
autoSelect: true,
minLength: 2,
delay: 400,
source: function (query, process) {
$.ajax({
url: '/search/searchCities',
data: {q: query},
dataType: 'json'
})
.done(function(response) {
console.log(response.data);
return process(response.data);
});
}
});
});
</script>
My backend code returns an json object like
{status: "OK", data: ["Moscow", "New York", "Odessa"]}
by php code
<?= echo json_encode(["status" => "OK", "data" => ["Moscow", "New York", "Odessa"]]) ?>
After I type 2 or more letters in the input there's an error in the browser console like this
GET http://localhost/search/searchCities?q=mo 200 OK
TypeError: a is undefined
...rep:function(a,b,c){for(var d,e=[],f=0,g=a.length,h=!c;g>f;f++)d=!b(a[f],f),d!==...
jquery.min.js (row 2, col 3476)
["Moscow"]
I see the dropdown with "Moscow" option, I can choose it and everything would be fine if i had not got the error in console. Please, show me my mistake.
I tried to use jquery.js (not the min-version). The error was
TypeError: elems is undefined
length = elems.length,
jquery.js (row 459, col 4)
I guess that something wrong with data type but i can't find it by myself.
事实证明,如果我使用bootstrap3-typeahead.js,bootstrap3-typeahead.min.js中有错误-浏览器控制台中没有错误。
