允许打开所有 JQuery 手风琴部分

如何解决允许打开所有 JQuery 手风琴部分

我有一个功能齐全的 JQuery 手风琴，除了我希望能够打开所有部分。要实现这一点，用户必须能够打开一个部分，而另一个部分不会折叠。

这有点违反直觉，但现实生活中的手风琴也可以完全扩展。

$(document).ready(function() {
  $("#accordion").accordion({
    heightStyle: 'content',collapsible: true,toggle: false
  });
});

<script src="https://code.jquery.com/ui/1.12.0/jquery-ui.min.js"></script>
<link rel="stylesheet" href="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

<div id="accordion">
  <h3>Section 1</h3>
  <div>
    A
  </div>
  <h3>Section 2</h3>
  <div>
    B
  </div>
  <h3>Section 3</h3>
  <div>
    C
  </div>
  <h3>Section 4</h3>
  <div>
    D
  </div>
</div>

我将如何实现这一目标？

解决方法

试试这个：

var headers = $('#accordion .accordion-header');
var contentAreas = $('#accordion .ui-accordion-content ').hide();
var expandLink = $('.accordion-expand-all');

// add the accordion functionality
headers.click(function() {
    var panel = $(this).next();
    var isOpen = panel.is(':visible');
 
    // open or close as necessary
    panel[isOpen? 'slideUp': 'slideDown']()
        // trigger the correct custom event
        .trigger(isOpen? 'hide': 'show');

    // stop the link from causing a pagescroll
    return false;
});

// hook up the expand/collapse all
expandLink.click(function(){
    $(".ui-accordion-content").show();
});

body {
    font-family: "Trebuchet MS","Helvetica","Arial","Verdana","sans-serif";
    font-size: 62.5%;
}

.accordion-expand-holder {
    text-align: center;
    padding: 10px;
}
