Question

我正在使用Jquery Accordion来显示和隐藏某些div。还有一个“全部显示”/“全部展开”按钮。一切正常，除了当我点击第1节的标题然后点击第2节的标题时，第1节仍然展开。当另一个打开同时保留全部显示并隐藏所有功能时，如何使其折叠？我在StackOverFlow，jquery论坛和小提琴上尝试了多个答案。他们每个人似乎都缺少一件事。有人可以帮帮我吗？

这是一个几乎接近我想要的小提琴：http://jsfiddle.net/apd8526c/

这就是它正在做的事情：

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(){
    var isAllOpen = $(this).data('isAllOpen');

    contentAreas[isAllOpen? 'hide': 'show']()
        .trigger(isAllOpen? 'hide': 'show');
});

// when panels open or close, check to see if they're all open
contentAreas.on({
    // whenever we open a panel, check to see if they're all open
    // if all open, swap the button to collapser
    show: function(){
        var isAllOpen = !contentAreas.is(':hidden');   
        if(isAllOpen){
            expandLink.text('Collapse All')
                .data('isAllOpen', true);
        }
    },
    // whenever we close a panel, check to see if they're all open
    // if not all open, swap the button to expander
    hide: function(){
        var isAllOpen = !contentAreas.is(':hidden');
        if(!isAllOpen){
            expandLink.text('Expand all')
            .data('isAllOpen', false);
        } 
    }
});
