所以我有一个导航菜单,可以在纵向或横向观看平板电脑时更改样式。它将最后几个菜单项折叠到另一个下拉菜单中。然而,菜单不会在方向更改时更新,只有在刷新后才会更新。

Jquery Modernizr代码:

if(Modernizr.mq('(max-device-width: 800px) and (orientation: portrait)')){
    // portrait stuff
        // unhides last few menu items
        $('#menu-primary-items > li:nth-last-child(-n+3)').css('display', 'block');

        // remove hide and first child class originally assigned to it from it's ul parent
        // then add the more list item to the end of the nav menu
        $('.moreItem').removeClass('hide first-child').appendTo('#menu-primary-items');

        // grab the last two items of the nav menu and insert into the more list item menu
        $('.topNavigation .toplevel').slice(-2).appendTo('.moreMenu');
    } 

有什么建议吗?

所以似乎将函数包装在resize侦听器中使它工作!当有一个else语句时,似乎也工作得更好。只需要在其他设备上进行进一步测试。

更新的代码:

$(window).bind('resize', function(){

    if(Modernizr.mq('(max-device-width: 800px) and (orientation: portrait)')){
    // portrait stuff
        // unhides last few menu items
        $('#menu-primary-items > li:nth-last-child(-n+3)').css('display', 'block');

        // remove hide and first child class originally assigned to it from it's ul parent
        // then add the more list item to the end of the nav menu
        $('.moreItem').removeClass('hide first-child').appendTo('#menu-primary-items');

        // grab the last two items of the nav menu and insert into the more list item menu
        $('.topNavigation .toplevel').slice(-2).appendTo('.moreMenu');
    } else if(Modernizr.mq('(max-device-width: 1280px) and (max-device-height: 800px) and (orientation: landscape)') || Modernizr.mq('(max-device-width: 1024px) and (orientation: landscape)')){

        $('.moreMenu').children().appendTo('#menu-primary-items');

        $('.moreItem').addClass('hide first-child').appendTo('.moreItemHolder');

        $('#menu-primary-items > li:nth-last-child(-n+3)').css('display', 'block');

    }
});
