Question

我想知道如何使用jquery / Ajax从PHP文件中获取PHP数组字段值。事实上，我有三个文件：mapage.html，moslem.php和moslem1.php。您可以在下面找到每个文件的代码。

mapage.html的代码：

<script type="text/javascript">
    $(document).ready(function() {
        setTimeout( test, 1000);
    });
    function test() {
        $.ajax({
            url: 'moslem.php',
            type: 'POST',
            success: function(data) {
                var max;
                max = data;
                setTimeout( test1, 500);
                function test1() {
                    $.ajax({
                        url: 'moslem1.php',
                        type: 'POST',
                        success: function(data1) {
                            document.write(data1+"<br>");
                        }
                    });
                }
            }
        });
        setTimeout( test, 1000);
    }

moslem.php的代码：

    <?php
$con=mysqli_connect("localhost","root","","test");
if (mysqli_connect_errno()) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM jqcalendar ORDER BY id DESC LIMIT 0, 1");
while($row = mysqli_fetch_array($result)) {
    $max=$row['Id'];
}
echo $max;
mysqli_close($con);
?>

moslem1.php的代码：

    <?php
$con = mysqli_connect("localhost", "root", "", "test");
if (mysqli_connect_errno()) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con, "SELECT * FROM jqcalendar ORDER BY id DESC LIMIT 0, 1");
while ($row = mysqli_fetch_array($result)) {
    $notification = array('id' => $row['Id'], 'subject' => $row['Subject'], 'location' => $row['Location'], 'description' => $row['Description'], 'starttime' => $row['StartTime'], 'endtime' => $row['EndTime']);
}
print_r($notification);
mysqli_close($con);
?>

好吧，当我运行文件mapage.html时，它每隔一秒显示以下行：

Array ( [id] => 22 [subject] => reading books [location] => at home [description] => reading some books. [starttime] => 2014-05-21 11:00:00 [endtime] => 2014-05-21 12:00:00 )

因此，您可以在上面看到它显示数组的内容＆＃34; notification＆＃34;存在于moslem1.php的代码中。现在，我的问题是如何修改下面的行以仅显示该数组的字段值（例如，字段＆＃34; subject＆＃34;或任何其他字段的值）：

document.write(data1+"<br>");

提前致谢。

将dataType:'JSON',添加到您的Ajax请求中，并将print_r($notification);更改为echo json_encode($notification);中的moslem1.php，然后您就可以document.write(data1.subject);
