我無法應付這個問題的解決方案。問題內容:用ajax選擇內容
select2.full.js:4025 Uncaught TypeError: Cannot read property 'slice' of undefined
at DecoratedClass.HidePlaceholder.removePlaceholder (select2.full.js:4025)
at DecoratedClass.removePlaceholder (select2.full.js:594)
at DecoratedClass.HidePlaceholder.append (select2.full.js:4008)
at DecoratedClass.append (select2.full.js:594)
at Select2. (select2.full.js:1025)
at Select2.Observable.invoke (select2.full.js:651)

at Select2.trigger (select2.full.js:5489)

at Object.options.transport.self.trigger.message (select2.full.js:3482)
我在做什麼錯?
$(document).ready(function(){
$('#select2').select2({
minimumInputLength:1,
\t \t \t width: '300px',
placeholder:"Select Parent Menu",
ajax: {
type:"get",
url: "../test/inc/ajax/ajaxlux.php",
dataType: 'json',
quietMillis: 100,
data: function(params) {
return {
query: params.term, //search term
page_limit: 10 // page size \t
\t \t \t \t \t \t \t
};
\t \t \t \t \t \t console.log(data);
},
results: function(data) {
var newData = [];
for (var i = 0; i < data.length; i++) {
newData.push({
id: item.FormID //id part present in data
, text: item.FormName //string to be displayed
});
}
return { results: newData };
},
}
});
});
<select id="select2">
</select>';
而且ajaxlux.php:
$sql = "
SELECT ".$prefix."product.product_id,".$prefix."product.product_name
FROM ".$prefix."product
WHERE ".$prefix."product.product_name LIKE '%".$_GET['query']."%'
AND ".$prefix."product.product_active = '1'
ORDER BY product_name ASC LIMIT 10 " ;
$result= mysqli_query($link,$sql) or die(mysqli_error());
$json = [];
while($row = mysqli_fetch_assoc($result)){
$json[] = array (
'FormID' => $row['product_id'],
'FormName' => $row['product_name'],
);
}
echo json_encode($json, JSON_UNESCAPED_UNICODE);
}
我通過互聯網和相同的代碼,我爲別人工作,在許多網站看了。
如果問題發生的客戶端,它發生的時候? AJAX調用返回之前還是之後?如果是,那麼AJAX調用返回什麼? – David
當我在Selecta中輸入某些內容時會發生這種情況。所以客戶端。 – elohard
我不知道阿賈克斯,我只是想絆倒我這一個例子。從我看到的 – elohard
