javascript - 常见问题解答 - 手风琴展开/折叠功能
问题描述
在现有的展开/折叠“FAQ”手风琴页面上工作，并希望让“展开/折叠”功能正常工作。
我设法让页面开始时所有内容都折叠了，但是当我单击任何一列展开然后单击另一列时，原来的一列不会折叠。
重要的是，我想保持搜索功能不变。
$('.collapse').collapse(); // Collapse all
// This section makes the search work.
(function() {
var searchTerm, panelContainerId;
$('#accordion_search_bar').on('change keyup', function() {
searchTerm = $(this).val();
$('#accordion > .panel').each(function() {
panelContainerId = '#' + $(this).attr('id');
// Makes search to be case insesitive
$.extend($.expr[':'], {
'contains': function(elem, i, match, array) {
return (elem.textContent || elem.innerText || '').toLowerCase()
.indexOf((match[3] || "").toLowerCase()) >= 0;
}
});
// END Makes search to be case insesitive
// Show and Hide Triggers
$(panelContainerId + ':not(:contains(' + searchTerm + '))').hide(); //Hide the rows that done contain the search query.
$(panelContainerId + ':contains(' + searchTerm + ')').show(); //Show the rows that do!
});
});

<p>The lion (Panthera leo) is one of the big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies in Africa. With some males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in India (where an endangered remnant population resides in Gir Forest National Park). In ancient historic times, their range was in most of Africa, including North Africa, and across Eurasia from Greece and southeastern Europe to India. In the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans: Panthera leo spelaea lived in northern and western Europe and Panthera leo atrox lived in the Americas from the Yukon to Peru.</p>

<p>Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.</p>

<p>The meerkat or suricate (Suricata suricatta) is a small carnivoran belonging to the mongoose family (Herpestidae). It is the only member of the genus Suricata. Meerkats live in all parts of the Kalahari Desert in Botswana, in much of the Namib Desert in Namibia and southwestern Angola, and in South Africa. A group of meerkats is called a "mob", "gang" or "clan". A meerkat clan often contains about 20 meerkats, but some super-families have 50 or more members. In captivity, meerkats have an average life span of 12–14 years, and about half this in the wild.</p>

</html>所有项目都开始折叠，基本上当用户单击第一只爪子展开然后单击另一只爪子时，第一只爪子应该“折叠”。当用户单击另一只爪子展开时，前一个展开的爪子应该折叠，以便一次只留下一个展开的项目。
解决方案
如果您希望面板开始折叠，请不要使用inclass。
调用$('.collapse').collapse();不会折叠您的面板，它会使用默认选项重新激活.collapse元素，覆盖（因此面板关闭）和（因此您会失去一次一个面板的行为）。.indata-parent
您也不需要:contains在每次按键时定义伪选择器三次。一次就够了。而且您不需要显式循环所有#accordion的.panels，只需使用足够广泛的选择器。
// Not necessary.
// $('.collapse').collapse();
// This section makes the search work.
(function() {
// Makes search to be case insesitive
$.extend($.expr[':'], {
'contains': function(elem, i, match, array) {
return (elem.textContent || elem.innerText || '').toLowerCase()
.indexOf((match[3] || "").toLowerCase()) >= 0;
}
});
// END Makes search to be case insesitive
$('#accordion_search_bar').on('change keyup', function() {
var searchTerm = $(this).val();
$('#accordion > .panel').hide(); // Hide all rows.
$('#accordion > .panel:contains(' + searchTerm + ')').show(); // Show the rows that match the search query.
