我想在 yii2 中使用pjax进行分页。
当用户单击下一页时，我只想重新加载一个包含动态内容的div。
我已将pjax::begin()和pjax::end()放在div的开头和结尾。
这是我的控制器代码：
public function actionRestaurantDetails(){
$this->layout = "detail";
if(isset($_REQUEST['rid']) && !empty($_REQUEST['rid'])){
$rid = $_REQUEST['rid'];
$snRestaurantsDetail = Restaurants::find()->where(['id'=>$_REQUEST['rid']])->one();
$snRestaurantMenuCategoryArr = MenuCategories::find()->where(["status"=>"1"])->all();
$snRestaurantMenusArr = RestaurantMenu::find()->where(['restaurant_id'=>$_REQUEST['rid'],'status'=>"1"])->all();
$query = RestaurantsGallery::find()->where(['restaurant_id'=>$_REQUEST['rid'],'status'=>"1"]);
$snRestaurantgallerysArr = RestaurantsGallery::find()->where(['restaurant_id'=>$_REQUEST['rid'],'status'=>"1"])->all();
$pagination = new Pagination(['totalCount' => $query->count(), 'pageSize'=>3]);
$models = $query->offset($pagination->offset)
->limit($pagination->limit)
->all();
$snRestaurantLayoutsArr = $snRestaurantsDetail->getRestaurantLayouts();
$snRestaurantTablesArr = $snRestaurantsDetail->getRestaurantTables();
$snRestaurantWorkingHoursArr = $snRestaurantsDetail->getRestaurantWorkingHours();
$snRestaurantMealTimesArr = $snRestaurantsDetail->getRestaurentMealTimes();
//p($snRestaurantsDetail);
}
return $this->render('restaurant_detail', [
'snRestaurantsDetail' => $snRestaurantsDetail,
'snRestaurantMenuCategoryArr' => $snRestaurantMenuCategoryArr,
'snRestaurantMenusArr' => $snRestaurantMenusArr,
'snRestaurantMealTimesArr' => $snRestaurantMealTimesArr,
'snRestaurantWorkingHoursArr' => $snRestaurantWorkingHoursArr,
'snRestaurantgallerysArr' => $snRestaurantgallerysArr,
'models' => $models,
'pagination' => $pagination,
]);
}
这是我的观点：

Pjax::end();

}?>
这是我的js代码：
$.pjax.reload({container: '#gallery_r'});
我调用此jquery在pjax加载后添加类以显示内容：
jQuery(document).on("pjax:success", "#gallery_r", function(event){
contentWayPoint();
}
);
var contentWayPoint = function() {
var i = 0;
$('.site-animate').waypoint( function( direction ) {
if( direction === 'down' && !$(this.element).hasClass('site-animated') ) {
i++;
$(this.element).addClass('item-animate');
setTimeout(function(){
$('body .site-animate.item-animate').each(function(k){
var el = $(this);
setTimeout( function () {
var effect = el.data('animate-effect');
if ( effect === 'fadeIn') {
el.addClass('fadeIn site-animated');
} else if ( effect === 'fadeInLeft') {
el.addClass('fadeInLeft site-animated');
} else if ( effect === 'fadeInRight') {
el.addClass('fadeInRight site-animated');
} else {
el.addClass('fadeInUp site-animated');
}
el.removeClass('item-animate');
}, k * 50, 'easeInOutExpo' );
});
}, 100);
}
} , { offset: '95%' } );
};
然后在一个按钮上单击，我这样称呼该URL：
<p class="mb-0"><a href="<?php echo Yii::$app->urlManager->createUrl(['site/restaurant-details',"rid"=>$restaurant->id]) ?>" class="btn btn-primary btn-sm">Read More</a></p>
此URL称为ajax调用，仅加载pjax容器div，当我手动重新加载此页面时，它将显示整个页面。我不知道为什么会这样？
答案 0 :(得分：0)
您应将LinkPager移到Pjax范围内。
<?php
Pjax::begin(['id' => 'gallery_r']);
if (!empty($models)) {
foreach ($models as $key => $image) {
?>
<div class="col-md-4 site-animate">
<a href="<?php echo Yii::getAlias('@web') . "../../../uploads/" . $image->image_name; ?>" class="site-thumbnail image-popup">
<img src="<?php echo Yii::getAlias('@web') . "../../../uploads/" . $image->image_name; ?>" alt="chiefsRS" class="img-fluid" style="width:80%;height:50vh;" title="<?= $image->image_title; ?>">
</a>
</div>
<?php
}
echo \yii\widgets\LinkPager::widget([
'pagination' => $pagination,
]);
Pjax::end();
}
?>
