[英]jquery autocomplete dont return suggestions data onselec
I have input with id aktForm_tiekejas and is jquery autocomplete code: 我输入的ID为aktForm_tiekejas,是jquery自动完成代码:
$('#aktForm_tiekejas').autocomplete({
serviceUrl: '_tiekejas.php',
width: 185,
deferRequestBy: 0,
noCache: true,
onSelect: function(suggestion) {alert('You selected:'+suggestion.value+','+suggestion.data);}
});
_tiekejas.php: _tiekejas.php:
<?php
include("../Setup.php");
$query = ($_GET['query']);
$reply = array();
$reply['query'] = $query;
$reply['suggestions'] = array();
$reply['data'] = array();
$res = mysql_query("SELECT id,pavadinimas FROM sarasas_tiekejas WHERE pavadinimas LIKE '%$query%' ORDER BY pavadinimas ASC");
while ($row = mysql_fetch_array($res)) {
$reply['suggestions'][] = $row['pavadinimas'];
$reply['data'][] = $row['id'];
}
mysql_close();
echo json_encode($reply);
?>
If query is 'vac' php returns from server: 如果查询为“ vac”,则php从服务器返回:
{"query":"vac","suggestions":["UAB Vivacitas"],"data":["866"]}
but 但
alert('You selected:'+suggestion.value+','+suggestion.data);
doesn't alert data (866) 不提醒数据(866)
why?... 为什么?...
Probably because suggestion.value doesn't exist. 可能是因为proposal.value不存在。 Looking at your JSON response code I can see the suggestion.data but no suggestion.value.
查看您的JSON响应代码,我可以看到uggestination.data,但没有uggestination.value。 Since JS will be looking for a value that doesn't exist it will throw an error.
由于JS将查找不存在的值,因此将引发错误。 Also you're missing out the array for the second part of the return.
另外,您会错过返回的第二部分的数组。 Try this:
尝试这个:
alert('You selected: '+suggestion.data[0]);
If you need to iterate through your data subsets do something like: 如果您需要遍历数据子集,请执行以下操作:
for(i in suggestion.data){
alert('You selected: '+suggestion.data[i]);
}
