我想在 Magento 属性中制作一个显示更少/更多按钮。目前，导航中有 50 种不同颜色的块。是否可以减少显示/显示更多按钮？我在互联网上找到的唯一内容是：
Go to the app/design/frontend/default/YOUR_THEME/template/catalog/layer/filter.phtml
Replace the existing code with:
<ol>
<?php
$displaySize=4;
$i=0;
$filterName=strtolower($this->getName());
$cnt=count($this->getItems());
foreach ($this->getItems() as $_item): ?>
<?php if($i == $displaySize) { ?>
<div id="more-<?php echo $filterName?>"><a >Show Filter</a></div>
<div id="cont-<?php echo $filterName?>">
<?php } ?>
<li>
<?php if ($_item->getCount() > 0): ?>
<a href="<?php echo $this->urlEscape($_item->getUrl()) ?>"><?php echo $_item->getLabel() ?></a>
<?php else: echo $_item->getLabel() ?>
<?php endif; ?>
(<?php echo $_item->getCount() ?>)
</li>
<?php $i++;
if($i==$cnt && $cnt > $displaySize)
echo '<div id="less-'.$filterName.'"><a >Hide Filter</a></div></div>'; ?>
<?php endforeach ?>
</ol>
Now open the file view.phtml in the same folder
Add in the beginning:
<?php $displaySize=4;
$hiddenFilters=array(); ?>
Add just before if($_filter->getItemsCount()):
if($_filter->getItemsCount() > $displaySize)
$hiddenFilters[]=strtolower($_filter->getName());
Add at the end of file:
<script>
Event.observe(window, ‘load’,
function() {
<?php foreach($hiddenFilters as $v)
{
echo "$('cont-".$v."').hide();";
} ?>
}
);
// Register event ‘click’ and associated call back.
Event.observe(document, ‘click’, respondToClick);
// Callback function to handle the event.
function respondToClick(event) {
var element = event.element();
//------
<?php foreach($hiddenFilters as $p)
{
echo "if(element.up('div').id=='more-".$p."')
{
$('cont-".$p."').show();
$('more-".$p."').hide();
}
if(element.up('div').id=='less-".$p."')
{
$('cont-".$p."').hide();
$('more-".$p."').show();
}";
} ?>
//-----
}
</script>
该脚本是否应该运行良好，并且构建良好？先感谢您！
