Joe主题 增加首页分页功能

1.在主题的public文件夹下新建文件pagination.php,文件内容如下:

<?php if ($this->options->JPageStatus === 'default') : ?>
    <?php $this->pageNav(
        '<svg class="icon icon-prev" viewBox="0 0 1024 1024" xmlns="http://www.w3.org/2000/svg" width="12" height="12"><path d="M822.272 146.944l-396.8 396.8c-19.456 19.456-51.2 19.456-70.656 0-18.944-19.456-18.944-51.2 0-70.656l396.8-396.8c19.456-19.456 51.2-19.456 70.656 0 18.944 19.456 18.944 45.056 0 70.656z"/><path d="M745.472 940.544l-396.8-396.8c-19.456-19.456-19.456-51.2 0-70.656 19.456-19.456 51.2-19.456 70.656 0l403.456 390.144c19.456 25.6 19.456 51.2 0 76.8-26.112 19.968-51.712 19.968-77.312.512zm-564.224-63.488c0-3.584 0-7.68.512-11.264h-.512v-714.24h.512c-.512-3.584-.512-7.168-.512-11.264 0-43.008 21.504-78.336 48.128-78.336s48.128 34.816 48.128 78.336c0 3.584 0 7.68-.512 11.264h.512v714.24h-.512c.512 3.584.512 7.168.512 11.264 0 43.008-21.504 78.336-48.128 78.336s-48.128-35.328-48.128-78.336z"/></svg>',
        '<svg class="icon icon-next" viewBox="0 0 1024 1024" xmlns="http://www.w3.org/2000/svg" width="12" height="12"><path d="M822.272 146.944l-396.8 396.8c-19.456 19.456-51.2 19.456-70.656 0-18.944-19.456-18.944-51.2 0-70.656l396.8-396.8c19.456-19.456 51.2-19.456 70.656 0 18.944 19.456 18.944 45.056 0 70.656z"/><path d="M745.472 940.544l-396.8-396.8c-19.456-19.456-19.456-51.2 0-70.656 19.456-19.456 51.2-19.456 70.656 0l403.456 390.144c19.456 25.6 19.456 51.2 0 76.8-26.112 19.968-51.712 19.968-77.312.512zm-564.224-63.488c0-3.584 0-7.68.512-11.264h-.512v-714.24h.512c-.512-3.584-.512-7.168-.512-11.264 0-43.008 21.504-78.336 48.128-78.336s48.128 34.816 48.128 78.336c0 3.584 0 7.68-.512 11.264h.512v714.24h-.512c.512 3.584.512 7.168.512 11.264 0 43.008-21.504 78.336-48.128 78.336s-48.128-35.328-48.128-78.336z"/></svg>',
        1,
        '...',
        array(
            'wrapTag' => 'ul',
            'wrapClass' => 'joe_pagination',
            'itemTag' => 'li',
            'textTag' => 'a',
            'currentClass' => 'active',
            'prevClass' => 'prev',
            'nextClass' => 'next'
        )
    );
    ?>
<?php else : ?>
    <div class="joe_load">查看更多</div>
<?php endif ?>

2.修改主题目录下的index.php,添加如下代码,注意:此代码需添加在joe.index.min.js文件引入之前。

<script>
    document.addEventListener('DOMContentLoaded', () => {
        window.Joe.PAGE_INDEX = '<?php echo $this->_currentPage; ?>' || 1;
    });
</script>

3.在index.php中找到

<div class="joe_load">查看更多</div>

替换为

<?php $this->need('public/pagination.php'); ?>

4.在主题目录下的functions.php文件中增加下面的代码,用于后台设置,这里默认的使用按钮切换形式,如果需求默认为点击加载形式可以将下面第四行的default改为ajax。

$JPageStatus = new Typecho_Widget_Helper_Form_Element_Select(
    'JPageStatus',
    array('default' => '按钮切换形式(默认)', 'ajax' => '点击加载形式'),
    'default',
    '选择首页的分页形式',
    '介绍:选择一款您所喜欢的分页形式'
);
$JPageStatus->setAttribute('class', 'joe_content joe_other');
$form->addInput($JPageStatus->multiMode());

5.修改JS文件,找到主题目录下/assets/js/joe.index.min.js,将page:1替换为page:window.Joe.PAGE_INDEX
