jQuery UI手风琴:一次打开多个面板 [英] jQuery UI accordion: open multiple panels at once

问题描述

我正在尝试创建一种能够一次扩展多个面板的手风琴.我试图在jQuery UI API中找到它，但是还没有找到正确的方法.

I'm trying to create an accordion able to expand multiple panels at once. I have tried to find it in the jQuery UI API, but I haven't yet found the proper way.

请告诉我是否有使用jQuery UI手风琴进行此操作的方法.

Please let me know if there is a way of doing this using jQuery UI accordion.

推荐答案

正如其他人指出的那样，Accordion小部件没有API选项可以直接执行此操作.但是，如果必须使用该小部件，则可以通过使用

As others have noted, the Accordion widget does not have an API option to do this directly. However, if you must use the widget, it is possible to achieve this by using the beforeActivate event handler option to subvert and emulate the default behavior of the widget.

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
    }
});
