Yii2 Scroll Pager (Y2SP) turns your regular paginated page into an infinite scrolling page using AJAX.
Y2SP works with a Pagination
object which specifies the totally number of pages and the current page number.
Pager is build with help of JQuery Infinite Ajax Scroll plugin.
The preferred way to install this extension is through Composer.
Either run
php composer.phar require kop/yii2-scroll-pager "dev-master"
or add
"kop/yii2-scroll-pager": "dev-master"
to the require
section of your composer.json
file.
Just pass the ScrollPager class name to the ListView pager
configuration.
Make sure that items in your list have some classes that can be used as JavaScript selectors.
echo ListView::widget([
'dataProvider' => $dataProvider,
'itemOptions' => ['class' => 'item'],
'itemView' => '_item_view',
'pager' => ['class' => \kop\y2sp\ScrollPager::className()]
]);
Here you can see how you can use variable {{ias}}
for events. In this example are added the new settings linkPager
, linkPagerOptions
and linkPagerWrapperTemplate
.
echo ListView::widget([
'options' => ['class' => 'list-view'],
'dataProvider' => $listDataProvider,
'itemOptions' => ['tag' => false],
'itemView' => '_list_item',
'summary' => '',
'layout' => '{items}{pager}',
'pager' => [
'class' => \kop\y2sp\ScrollPager::className(),
'item' => 'article',
'next' => '.next a',
'paginationSelector' => '.list-view .pagination',
'triggerText' => Yii::t('app', 'Show more'),
'triggerTemplate' => '<span class="reveal-btn">{text}</span>',
'noneLeftText' => '',
'noneLeftTemplate' => '',
'spinnerSrc' => '',
'spinnerTemplate' => '',
'linkPager' => [
'prevPageCssClass' => 'btn-link prev',
'nextPageCssClass' => 'btn-link next',
'prevPageLabel' => '<span class="prev-page">prev</span>',
'nextPageLabel' => '<span class="next-page">next</span>',
],
'linkPagerOptions' => [
'class' => 'pagination',
],
'linkPagerWrapperTemplate' => '<div class="button-news-more"><div class="wrapper"><div class="paging">{pager}</div></div></div>',
'eventOnPageChange' => 'function() {{{ias}}.hidePagination();}',
'eventOnReady' => 'function() {{{ias}}.restorePagination();}',
],
]);
echo GridView::widget([
'dataProvider' => $dataProvider,
'pager' => [
'class' => \kop\y2sp\ScrollPager::className(),
'container' => '.grid-view tbody',
'item' => 'tr',
'paginationSelector' => '.grid-view .pagination',
'triggerTemplate' => '<tr class="ias-trigger"><td colspan="100%" style="text-align: center"><a style="cursor: pointer">{text}</a></td></tr>',
],
]);
