如何在没有数据库的情况下创建AJAX分页?

标签: javascript php jquery ajax pagination

是否可以在没有MySQL帮助的情况下获取AJAX分页页面?我不能只添加一个PHP文件,其中包含我需要显示的文本和标记,并通过点击页码向用户提供该内容吗?那么这可以通过纯jQuery和PHP来实现吗?你会采用什么样的代码来保持简单,我的意思是我需要在我的网站上添加3个文本墙,但在页面上一次添加它们会让用户感到困惑。因此,我决定找到一种方法,并根据用户的决定一次只保留其中一种。代码示例会很棒!

修改 PHP代码应该是这样的吗?

<?php
    htmlspecialchars($_GET["page_number"]);
    if ($page_number == 1)
    {
        $text = var_export($text1, true);
    }

    if ($page_numer == 2)
    {
        $text = var_export($text2, true);
    }

    if ($page_number == 3)
    {
        $text = var_export($text3, true);
    }

    $text1 = 'some looong text...';
    $text2 = 'another wall of text';
    $text3 = 'and yet another one';
?>

是的,你可以。你必须遵循分页规则。您需要在网址中传递页码和记录限制。

www.example.com/index.php?page=1&limit=10

现在你创建一个文本或php文件并使用var_export导出所有数据以返回数组或其他你喜欢的方式。

现在你必须得到页码,诀窍就在这里。

您从文本文件中获取的数组应按限制进行划分。

$rows = array_chunk($array,$_GET['limit']);

您对page = $ n的结果在这里。 $result = $row[$_GET['page']]

这是我的index.php文件。

<?php
$array = include_once('data.php');
$page = $_GET['page'] ? $_GET['page'] : 0;
$limit = $_GET['limit'];
$rows = array_chunk($array,$limit);
$result = $rows[$page];
?>
<table>
    <tr>
        <th>Id</th>
        <th>Name</th>
        <th>Desc</th>
        <th>Status</th>
    </tr>
    <?php
        foreach ($result as $res) {
    ?>
        <tr>
            <td><?php echo $res['id'] ?></td>
            <td><?php echo $res['name'] ?></td>
            <td><?php echo $res['desc'] ?></td>
            <td><?php echo $res['status'] ?></td>
        </tr>
    <?php
        }
    ?>
    <tr>
        <td colspan="2">
            <?php
                if($page>0)
                {
            ?>
            <a href="index.php?limit=<?php echo $limit; ?>&page=<?php echo ($page-1); ?>">Previous</a>
            <?php
                }
            ?>
        </td>
        <td colspan="2">
        <?php
            if (isset($rows[$page+1]))
            {
        ?>
            <a href="index.php?limit=<?php echo $limit; ?>&page=<?php echo ($page+1); ?>">Next</a>
        <?php
            }
        ?>
        </td>
    </tr>
</table>

这是data.php文件。我已经使用数组返回值。

    <?php
return
$array = [
    [
        'id' => 1,
        'name' => 'A',
        'desc' => 'Test',
        'status' => 'Active'
    ],
    [
        'id' => 2,
        'name' => 'B',
        'desc' => 'Test',
        'status' => 'Active'
    ],
    [
        'id' => 3,
        'name' => 'C',
        'desc' => 'Test',
        'status' => 'Active'
    ],
    [
        'id' => 4,
        'name' => 'D',
        'desc' => 'Test',
        'status' => 'Active'
    ],
    [
        'id' => 5,
        'name' => 'E',
        'desc' => 'Test',
        'status' => 'Active'
    ],
    [
        'id' => 6,
        'name' => 'F',
        'desc' => 'Test',
        'status' => 'Active'
    ],
];

可能是这样的吗?

HTML + JS:

<body>
<div id="text">

</div>
<ul id="pager">
    <li><a href="#0" class="active">1</a></li>
    <li><a href="#1">2</a></li>
    <li><a href="#2">3</a></li>
</ul>
<script type="text/javascript" src="//code.jquery.com/jquery-1.11.0.js"></script>
    <script type="text/javascript">
        jQuery(document).ready(function () {
            var pager = jQuery('#pager'),/* get pager list*/
                    currentInd = pager.find('.active').attr('href').replace('#', ''), /* get active element*/
                    text = jQuery('#text'); /* Text wrapper */
/* Get first text by Ajax*/
            jQuery.ajax({
                method: 'POST',
                url: '/index.php',
                data: {
                    page: currentInd
                }
            }).done(function (data) {
                text.text(data);
            });
        });

/** On pager link click */
        jQuery(document).on('click', '#pager a', function (e) {
            e.preventDefault(); 
            var ind = jQuery(this).attr('href').replace('#', ''),/* take number */
                    text=jQuery('#text'); /* text wrapper */
/* if this link is not active then send ajax request */
            if (!jQuery(this).hasClass('active')) {
                jQuery.ajax({
                    method: 'POST',
                    url: '/index.php',
                    data: {
                        page: ind
                    }
                }).done(function (data) {
                    jQuery('#pager').find('.active').removeClass('active');
                    jQuery(this).addClass('active');
                    text.text(data);
                });
            }
        });
    </script>
    </body>

注意:这是一个非常简单的例子
