我有这个代码非常有效。但我想用mysql。
以下是有效的代码：
<?php if (date('w') == 2) { { ?>
<script> $(function() {
var times = [
// mysql import start
{'id': '1', 'name': 'Mardi 5H55', 'end': new Date('2017-01-31 05:55:00'),},
{'id': '2', 'name': 'Mardi 8H40', 'end': new Date('2017-01-31 08:40:00'),},
{'id': '3', 'name': 'Mardi 11H30', 'end': new Date('2017-01-31 11:30:00'),},
{'id': '4', 'name': 'Mardi 14H05', 'end': new Date('2017-01-31 14:05:00'),}
// mysql import end
];
// Initialize the table values
$.each(times, function( key, value ) {
$('#mau-mpl').append('<tr><td>'+value.name+'</td><td>Hérault Transports (Ruban Bleu)</td><td>Montpellier</td><td><span id="player-'+value.id+'-expiration" class="label label-primary">Chargement encours...</span></td></tr>');
});
function countdown()
{
var now = new Date();
console.log('updating time');
$.each(times, function( key, value ) {
var left = value.end - now;
var days = Math.floor( left / (1000 * 60 * 60 * 24) );
var hours = Math.floor( (left % (1000 * 60 * 60 * 24) ) / (1000 * 60 * 60) );
var minutes = Math.floor( (left % (1000 * 60 * 60)) / (1000 * 60) );
var seconds = Math.floor( (left % (1000 * 60)) / 1000 );
displayTime = '';
if (days > 0) {
displayTime = + days + " jr ";
}
if (minutes > 0) {
displayTime = displayTime + hours + " H " + minutes + " Mn " + seconds + " Sec ";
}
echo = "Deja parti";
$('#player-'+value.id+'-expiration').text(displayTime)
});
}
timer = setInterval(countdown, 1000);
});</script><?php } } ?>
如您所见，我想要的数据是在 mysql import start 之后。 我制作了一个从mysql中获取数据的php文件，我得到了这个结果：
php文件是：
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "horaires";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); }
$sql = "SELECT id, jourheure, name, depart, arrivee FROM 2_mardi";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
// {'id': '1', 'name': '5H', 'end': new Date('2017-01-31, 05:55:00'),},";
echo "{'id': '" . $row["id"]. "', 'name': '" . $row['name'] ."', 'end': new Date('" . $row["jourheure"]. "" . $row["depart"]. "'),},<br>"; }
} $conn->close();
?>
+---+----------+---------------------+
| 1 | Mardi 5H | 2017-01-31 05:00:00 |
+---+----------+---------------------+
| 2 | Mardi 6H | 2017-01-31 06:00:00 |

如何将结果放在＆＃34; mysql import start＆＃34;之间的javascript变量中？和＆＃34; mysql导入结束＆＃34; ？
答案 0 :(得分：1)
你可以这样做：
var js = <?php echo "{'id': '" . $row["id"]. "', 'name': '" . $row['name'] ."', 'end': new Date('" . $row["jourheure"]. "" . $row["depart"]. "')}"; ?>
但警告，我最后删除了你对象上的坏字符：
echo "{'id': '" . $row["id"]. "', 'name': '" . $row['name'] ."', 'end': new Date('" . $row["jourheure"]. "" . $row["depart"]. "'),},<br>"; }

你可以用很多不同的方式设置var，ajax，在php代码中嵌入javascript代码......
如果你想获得一个PHP对象或var到javascript你需要在php代码中将对象序列化为JSON，那么你需要设置你的JSON字符串并将这个字符串转换为一个有效的javascript对象。
JSON是这样的字符串
"{'propertyname':'stringvalue','property2':true,'property3':null,'property':[...]}"
如果现在你可以在javascript代码块上解析JSON
的index.php
<?php
$result = getData() // your data like you want =>[ multiple objects ]
$resultJSON = json_encode($result); // "[{..},{...}]"
?>
<script>
var jsondata = parse.JSON('<?php echo $resultJSON ?>') ;
</script>
但我认为最好从php代码中分割html / javascript代码，例如从ajax获取变量。

您可以使用AJAX调用PHP脚本将数据存储到Javascript变量中。
在以下文件中，演示了使用JQuery的AJAX调用将数据存储到Javascript
中<?php if (date('w') == 2) { { ?>
<script>
$(function() {
var times = $.ajax({
url: 'api.php', //the script to call to get data
data: "", //you can insert url argumnets here to pass to api.php
//for example "id=5&parent=6"
dataType: 'json', //data format
success: function(data) //on recieve of reply
{
return data;
}
});
$.each(times, function(key, value) {
$('#mau-mpl').append('<tr><td>' + value.name + '</td><td>Hérault Transports (Ruban Bleu)</td><td>Montpellier</td><td><span id="player-' + value.id + '-expiration" class="label label-primary">Chargement encours...</span></td></tr>');
});
function countdown() {
var now = new Date();
console.log('updating time');
$.each(times, function(key, value) {
var left = value.end - now;
var days = Math.floor(left / (1000 * 60 * 60 * 24));
var hours = Math.floor((left % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((left % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((left % (1000 * 60)) / 1000);
displayTime = '';
if (days > 0) {
displayTime = +days + " jr ";
}
if (minutes > 0) {
displayTime = displayTime + hours + " H " + minutes + " Mn " + seconds + " Sec ";
}
echo = "Deja parti";
$('#player-' + value.id + '-expiration').text(displayTime)
});
}
timer = setInterval(countdown, 1000);
});
});</script><?php } } ?>
以下是从数据库中提取数据的代码 我们称这个文件为api。
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "horaires";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT id, jourheure, name, depart, arrivee FROM 2_mardi";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
//storing result into an array
$array = mysql_fetch_row($result);
}
$conn->close();
//encoding the array into JSON
echo json_encode($array);
?>
