运行并返回成功。函数initialiserBD()不会返回成功。当然，它是函数WL.JSONStore.get（）。add（）。then（）。fail（）
对象＆＃34; errorObject＆＃34;发送错误：-50 PERSISTENT_STORE_NOT_OPEN
remplireBD()
答案 0 :(得分：0)
我认为你的问题是双重的......
var collectionName="Personnes" ;）initialiserBD和remplireBD，而不是在remplireBD的成功回调中调用initialiserBD，这可能是.get()导致在init()完成之前尝试Here is the button that executes the PHP code:
<input type="submit" name="submit" value="SUBMIT QUIZ" id="btn4">
Here is the PHP code that is executed:
<?php
if (isset($_POST['submit'])) {
$items = array(); $j=0;
foreach($_POST['response'] as $key => $value) {
{$items[$j++] = $value;}
if($correctAnswerArray[$key] == $value) {
$rightAnswer++;
} else {
$wrongAnswer++;
}
}
$quizScore = ($rightAnswer / (4))*100;
$query1 = "UPDATE users SET quiz1_q1 = '$items[0]', quiz1_q2 = '$items[1]', quiz1_score = '$quizScore' WHERE userid = '" . $_SESSION['userid'] . "'";
$resultt = $conn->query($query1);
if($resultt)
{ echo "Your quiz has been saved"; }
else
{ echo '<h1>System Error</h1>'; }
?>
<script type="text/javascript">
var obj = <?php echo json_encode($items); ?>;
var objj = <?php echo json_encode($correctAnswerArray); ?>;
var objjj = <?php echo json_encode($quizScore); ?>;
makeRequest(obj, objj, objjj);
</script>
<?php } ?>
*Here is the makeRequest function (under the HEAD section)*
<script type="text/javascript">
function makeRequest(obj, objj, objjj) {
$.ajax( {
