[英]:first selector checks against parents parent, instead of parent container
由於需要浮動大的元素並試圖顯示它們,因此需要對布局中的大元素進行混洗。 本質上,始終需要將.gallery-large
類的.gallery-item
放在.item
內的第一個孩子,在.item
主#gallery_slideshow
內有幾個.item
容器。 目前,如果在第二個,第三個等中有一個大項目,那么該項目將作為第一個元素的第一個元素放置,因為我希望它留在它自己的內部。 例如,下面的代碼在第一個.item
包含5個元素, .item
包含2個大元素,而不是在最初的4個元素中包含1個大元素。
JS:
if($('.gallery-item').length > 1) {
$('.gallery-large').each(function(e) {
if(!$(this).is(':first')) {
$(this).insertBefore('.gallery-item:first');
//Reset height of owl carousel wrapper in case moved element was last
$('.owl-wrapper-outer').css('height', 'auto');
}
});
}
HTML:
<div id="gallery_slideshow" class="owl-carousel owl-theme">
<!-- Example page 1 -->
<div class="item row">
<div class="col-md-2 col-sm-3 col-xs-12 gallery-item gallery-small">

你可以做,
$(".gallery-large").each(function() {
$(this).parent().prepend(this);
});
prepend()
方法使其成為第一個孩子。 將其放在自己的父項之前,以保持正確的上下文。
