Question

我有jquery UI Accordion菜单。单击时显示特定的div元素。我想知道我是否刷新页面，例如div3处于活动状态（可见），如何在重新加载页面后再次激活div3？我试图用饼干解决这个问题，但没有运气。有没有人知道的演示？

感谢。

Answer 1

这是首先保存选定的手风琴状态然后在页面重新加载时甚至在下次访问时激活该状态的代码，只要cookie保持不变。

        jQuery(document).ready(function(){
            var act = 0;
            $( "#accordion" ).accordion({
                create: function(event, ui) {
                    //get index in cookie on accordion create event
                    if($.cookie('saved_index') != null){
                       act =  parseInt($.cookie('saved_index'));
                    }
                },
                change: function(event, ui) {
                    //set cookie for current index on change event
                    $.cookie('saved_index', null);
                    $.cookie('saved_index', ui.options.active);
                },
                active:parseInt($.cookie('saved_index'))
            });
        });

我使用过jquery cookie插件，你可以从这里下载https://github.com/carhartl/jquery-cookie/

使用新的1.10.1 UI

$(function () {
    var icons = {
        header: "ui-icon-triangle-1-e",
        activeHeader: "ui-icon-triangle-1-s",
        headerSelected: "ui-icon-triangle-1-s"
    };
    var act = 0;
    $( "#accordion" ).accordion({
        icons: icons,
        collapsible: true,
        clearStyle: true,
        heightStyle: "content",
        autoHeight: false,
        create: function(event, ui) {
            //get index in cookie on accordion create event
            if($.cookie('saved_index') != null){
               act =  parseInt($.cookie('saved_index'));
            }
        },
        activate: function(event, ui) {
            //set cookie for current index on change event
            var active = jQuery("#accordion").accordion('option', 'active');
            $.cookie('saved_index', null);
            $.cookie('saved_index', active);
        },
        active:parseInt($.cookie('saved_index'))
    });
    $( "#toggle" ).button().toggle(function() {
        $( "#accordion" ).accordion( "option", "icons", false );
    },
    function() {
        $( "#accordion" ).accordion( "option", "icons", icons );
    });
});

我不想使用cookie或会话变量。我选择了HTML5的本地存储。

这是我的解决方案：

$("#accordion").accordion({    
    //set localStorage for current index on activate event
    activate: function(event, ui) {        
        localStorage.setItem("accIndex", $(this).accordion("option", "active"));
    },
    active: parseInt(localStorage.getItem("accIndex"))    
});

上述解决方案的一小部分改进，用于管理所有条目关闭的手风琴（有效：假）：

$(function () {
    var myact = false;
    $( "#myaccordion" ).accordion({
        clearStyle: true,
        collapsible: true,      // allow to close completely
        create: function (event, ui) {
            //get index in cookie on accordion create event
            if (($.cookie('saved_index') != null) && ($.cookie('saved_index') != 'false')) {
                myact = parseInt($.cookie('saved_index'));
            }
        },
        change: function (event, ui) {
            //set cookie for current index on change event
            myact = ui.options.active;
            $.cookie('saved_index', null, { expires: 2, path: '/' });   // session cookie
            $.cookie('saved_index', myact, { expires: 2, path: '/' });
        },
        active: ($.cookie('saved_index') == null) ? 0 : ($.cookie('saved_index') == 'false') ? false : parseInt($.cookie('saved_index'))
    });
});

所选择的解决方案对我不起作用（jQuery 1.8.2，jQuery-UI 1.9.1）。

我修改了它，如下面的代码段所示：

jQuery(document).ready(function(){
    $( "#accordion" ).accordion({
        change: function(event, ui) {
            //set cookie for current index on change event
            $.cookie('saved_index', null);
            $.cookie('saved_index', $( "#accordion" )
                    .accordion( "option", "active" ));
        },
        active:parseInt($.cookie('saved_index'))
    });
});

@DeM解决方案对我有用，但我仍然希望得到这个错误。

在初始化之前无法调用手风琴上的方法;尝试做呼叫方法＆＃39;选项＆＃39;

以下修改对我有用：

$("#accordion").accordion({    
    //set localStorage for current index on activate event
    activate: function(event, ui) {  
        //Find the index of the header. This can be the class|element you specify in the "header" init argument.
        var index =  $(this).find("h3").index(ui.newHeader[0]);
        localStorage.setItem("accIndex", index);
    },
    // "|| 0" is used to activate first by default
    active: parseInt(localStorage.getItem("accIndex")) || 0   
});

即使刷新后，Jquery UI Accordion菜单也可以保存菜单状态
