每个下拉选项中的手风琴内容均无效

Question

我试图在每个下拉菜单中创建一个手风琴，但是它不能正常工作。显示在第一个下拉选项中的每个下拉选项的所有手风琴，如果我选择另一个下拉选项，则单击时手风琴无法打开。该如何解决？

这里是link for full snippet

$(function() {
  $('#faqDrodpown').change(function(){
    $('.faqs').hide();
    $('#' + $(this).val()).show();
  });

  $('#accordion-faq').find('.accordionfaq-toggle').click(function() { /*Expand or collapse this panel*/
        $(this).next().slideToggle('fast');
        $(".accordionfaq-content").not($(this).next()).slideUp('fast');
    });
});

Answer 1

只需将jquery $('#accordion-faq').find('.accordionfaq-toggle')更改为$('#accordion-faq .accordionfaq-toggle')，对我来说就可以正常使用

编辑： 更改了$('#faqDrodpown').change()函数以切换类hide 并在该类上添加了CSS，以隐藏内容，并在onload上隐藏其他常见问题，我添加了一些js代码

$(function() {
  $('.faqs').addClass('hide');
  $('#' + $('#faqDrodpown').val()).removeClass('hide');
    
  $('#faqDrodpown').change(function(){
    $('.faqs').addClass('hide');
    $('#' + $(this).val()).removeClass('hide');
  });
  
  $('#accordion-faq .accordionfaq-toggle').click(function(){ /*Expand or collapse this panel*/
        $(this).next('.accordionfaq-content').slideToggle('fast');
         $(".accordionfaq-content").not($(this).next()).slideUp('fast');
    });
});

.faq-dropdown {
  position: relative;
  display:block;
  margin-top:0.5em;
  padding:0;
}
.faq-dropdown select {
  width:100%;
  margin:0;
  background:none;
  border: 1px solid transparent;
  outline: none;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  appearance: none;
  -webkit-appearance: none;
  font-size:1.25em;
  color: #444;
  padding: .6em 1.9em .5em .8em;
  line-height:1.3;
}

.faq-dropdown::after {
  content: "";
  position: absolute;
  width: 9px;
  height: 8px;
  top: 50%;
  right: 1em;
  margin-top:-4px;
  z-index: 2;
  background: url("data:image/svg+xml;charset=utf8,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 16 12'%3E%3Cpolygon fill='rgb(102,102,102)' points='8,12 0,0 16,0'/%3E%3C/svg%3E") 0 0 no-repeat;

}

/* This hides native dropdown button arrow in IE 10/11+ so it will have the custom appearance, IE 9 and earlier get a native select */
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {

  select:focus::-ms-value {

  }
}

/* Firefox 7+ -- Will let us hide the arrow, but inconsistently (see FF 30 comment below). We've found the simplest way to hide the native styling in FF is to make the select bigger than its container. */
/* The specific FF selector used below successfully overrides the previous rule that turns off the custom icon; other FF hacky selectors we tried, like `*>.dropdown::after`, did not undo the previous rule */

/* Set overflow:hidden on the wrapper to clip the native select's arrow, this clips hte outline too so focus styles are less than ideal in FF */
_::-moz-progress-bar, body:last-child .dropdown {
  overflow: hidden;
}
/* Show only the custom icon */
_::-moz-progress-bar, body:last-child .dropdown:after {
  display: block;
}
_::-moz-progress-bar, body:last-child .dropdown select {
  /* increase padding to make room for menu icon */
  padding-right: 1.9em;
  /* `window` appearance with these text-indent and text-overflow values will hide the arrow FF up to v30 */
  -moz-appearance: window;
  text-indent: 0.01px;
  text-overflow: "";
  /* for FF 30+ on Windows 8, we need to make the select a bit longer to hide the native arrow */
  width: 110%;
}

/* At first we tried the following rule to hide the native select arrow in Firefox 30+ in Windows 8, but we'd rather simplify the CSS and widen the select for all versions of FF since this is a recurring issue in that browser */
/* @supports (-moz-appearance:meterbar) and (background-blend-mode:difference,normal) {
.dropdown select { width:110%; }
}   */


/* Firefox 7+ focus style - This works around the issue that -moz-appearance: window kills the normal select focus. Using semi-opaque because outline doesn't handle rounded corners */
_::-moz-progress-bar, body:last-child .dropdown select:focus {
  outline: 2px solid rgba(180,222,250, .7);
}


/* Opera - Pre-Blink nix the custom arrow, go with a native select button */
x:-o-prefocus, .dropdown::after {
  display:none;
}


/* Hover style */
.faq-dropdown:hover {
  border:1px solid #888;
}

/* Focus style */
select:focus {
  outline:none;
  box-shadow: 0 0 1px 3px rgba(180,222,250, 1);
  background-color:transparent;
  color: #222;
  border:1px solid #aaa;
}


/* Firefox focus has odd artifacts around the text, this kills that */
select:-moz-focusring {
  color: transparent;
  text-shadow: 0 0 0 #000;
}

option {
  font-weight:normal;
}


/* These are just demo button-y styles, style as you like */

将JS更改为

$(function() {

  $('#faqDrodpown').change(function(){
    $('.faqs').hide();
    $('#' + $(this).val()).show();
    var data = $("#faqDrodpown").find("option:selected").val();
    $('#accordion-faq-'+data).find('.accordionfaq-toggle').click(function() { 
          $(this).next().slideToggle('fast');
          $(".accordionfaq-content").not($(this).next()).slideUp('fast');
      });
  });
});

将HTML更改为

<div id="accordion-faq-red">
<div id="accordion-faq-yellow">
<div id="accordion-faq-blue">
