我写了一个简单的手风琴脚本，效果很好，我只想重构它以摆脱多个`$（this）.find。
我知道它很渺茫，但我讨厌重复自己，任何想法？最好的学习方法是问我想。
谢谢！
$.fn.acAccordion = function () {
$(this).find(".accordion-toggle .acc-state").show();
$(this).find(".accordion-content").hide();
$(this).find(".show").show();
$(this).find(".show").next().show();
$(this).find('.accordion-toggle').click(function(){
if($(this).next().is(":hidden")) {
$(this).next().slideToggle('fast');
$(".accordion-content").not($(this).next()).slideUp('fast');
}
});
};

您可以将重复元素缓存为开头。您也可以在同一元素上链接调用：
$.fn.acAccordion = function () {
var $el = $(this),
$contents = $el.find('.accordion-content');
$contents.hide().first().show();
$el.find('.accordion-toggle').click(function(){
var $next = $(this).next();
if ($next.is(":hidden")) {
$next.slideToggle('fast');
$contents.not($next).slideUp('fast');
}
});
};
$(".accordion").acAccordion();body {
font-size:16px;
font-family:sans-serif;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="accordion">
<div class="accordion-toggle show"><span class="accordion-title">Accordion 1</span></div>
<div class="accordion-content">
<p>Cras malesuada ultrices augue molestie risus.</p>
</div>
<div class="accordion-toggle"><span class="accordion-title">Accordion 2</span></div>
<div class="accordion-content">
