jQuery UI手风琴:一次打开多个面板

Question

我正在努力创造一种能够同时扩展多个面板的手风琴.我试图在jQuery UI API中找到它,但我还没有找到正确的方法.

如果有办法使用jQuery UI手风琴,请告诉我.

正如其他人所指出的那样,Accordion小部件没有直接执行此操作的API选项.但是,如果必须使用窗口小部件,则可以通过使用beforeActivate事件处理程序选项来破坏和模拟窗口小部件的默认行为来实现此目的.

例如:

$('#accordion').accordion({
    collapsible:true,

    beforeActivate: function(event, ui) {
         // The accordion believes a panel is being opened
        if (ui.newHeader[0]) {
            var currHeader  = ui.newHeader;
            var currContent = currHeader.next('.ui-accordion-content');
         // The accordion believes a panel is being closed
        } else {
            var currHeader  = ui.oldHeader;
            var currContent = currHeader.next('.ui-accordion-content');
        }
         // Since we've changed the default behavior, this detects the actual status
        var isPanelSelected = currHeader.attr('aria-selected') == 'true';

         // Toggle the panel's header
        currHeader.toggleClass('ui-corner-all',isPanelSelected).toggleClass('accordion-header-active ui-state-active ui-corner-top',!isPanelSelected).attr('aria-selected',((!isPanelSelected).toString()));

        // Toggle the panel's icon
        currHeader.children('.ui-icon').toggleClass('ui-icon-triangle-1-e',isPanelSelected).toggleClass('ui-icon-triangle-1-s',!isPanelSelected);

         // Toggle the panel's content
        currContent.toggleClass('accordion-content-active',!isPanelSelected)    
        if (isPanelSelected) { currContent.slideUp(); }  else { currContent.slideDown(); }

        return false; // Cancel the default action
    }
});

您可以编写多个叠加的手风琴,每个手风琴只有一个面板.这样,面板可以单独切换.

根据定义,手风琴是一组以某种方式切换的扩展元素.你不希望这样.您只需要一组扩展元素.使用jQuery构建它非常容易.它通常只需要:

$('.my-heading-class').on('click', function() {
   $(this).next('.my-content-class').slideToggle();
});

<div class="my-heading-class">My Heading</div>
<div class="my-content-class">My Content</div>
