我在 silverstripe 网站上运行了无限的 ajax 滚动。我还运行了“NoneLeft”扩展程序让人们知道,他们到达了底部。
IAScroll 在 ArticleHolder 页面中显示 ArticlePages 并按应有的方式显示“NoneLeft”文本。现在,当我直接只显示一个 ArticlePage(周围没有 ArticleHolder)时,它也显示了“NoneLeft”文本。有什么办法可以将其关闭或限制到某个页面?还是我必须从 jQuery 中取消绑定 ias?多谢
Silverstripe ArticleHolder.php
<?php
class ArticleHolder extends Page {
private static $allowed_children = array('ArticlePage');
}
class ArticleHolder_Controller extends Page_Controller {
public function PaginatedArticles(){
$paginatedItems = new PaginatedList(ArticlePage::get()->sort("Date DESC"), $this->request);
$paginatedItems->setPageLength(4);
return $paginatedItems;
}
}
脚本.js
var ias = jQuery.ias({
container: '#posts',
item: '.post',
pagination: '#pagination',
next: '.next',
delay: 0,
negativeMargin: 250,
history: true; }
});
// Adds a text when there are no more pages left to load
ias.extension(new IASNoneLeftExtension({
text: "You reached the end"
}));
#pagination 的 html 输出,当存在多个帖子时
<div id="pagination" class="line" style="display: none;">
<div class="unit size1of4 lineLeftRight lineLeft">
<p></p>
</div>
<div class="unit size1of4 lineLeftRight lineLeft">
<p> …
<a class="next" href="?start=4"> Next
</a>
</p>
</div>
<div class="unit size1of4 lastUnit lineLeftRight lineRight">
<p></p>
</div>
</div>
当只有一篇文章时,没有#pagination,但又是“NoneLeft”文本
<div id="ias_noneleft_1403162234904" class="ias-noneleft line">
<div class="unit size1of4 lineLeftRight lineLeft">
<p></p>
</div>
<div class="unit size2of4 lineMiddle">
<p>
You reached the end
</p>
</div>
<div class="unit size1of4 lastUnit lineLeftRight lineRight">
<p></p>
</div>
</div>
