如何同步兩個輪播滑塊 - Twitter Bootstrap

Question

我在一個頁面上有兩個滑塊（twitter bootstrap 3.3.6）。兩者都應通過相同的控制元素激活。當通過鍵盤箭頭鍵激活 - 非常快速的點擊 - ，我失去了同步;特別是在Firefox（v 49.0.1）中。這意味着標題滑塊中的圖像不屬於內容滑塊中的文本。

我怎麼能認識到，滑塊只有在兩個滑塊的動畫完成後纔會被激活？

我已經嘗試過使用jQuery-promise（），但錯誤保持不變。

感謝您的任何幫助。

$(document).ready(function() { 
 
    $('#sliderHeader, #sliderPartner').carousel({ 
 
    interval: false 
 
    }) 
 
    $('#sliderPartner a.left').click(function(event) { 
 
    event.stopPropagation(); 
 
    $(".carousel").promise().done(function() { 
 
     $('#sliderHeader').carousel('prev'); 
 
     $('#sliderPartner').carousel('prev'); 
 
    }); 
 
    }); 
 
    $('#sliderPartner a.right').click(function(event) { 
 
    event.stopPropagation(); 
 
    $(".carousel").promise().done(function() { 
 
     $('#sliderHeader').carousel('next'); 
 
     $('#sliderPartner').carousel('next'); 
 
    }); 
 
    }); 
 
    $('#sliderPartner .carousel-indicators li').click(function(event) { 
 
    event.stopPropagation(); 
 
    var indicatorNumber = $(this).attr('data-slide-to'); 
 
    $('#sliderHeader').carousel(parseInt(indicatorNumber)); 
 
    $('#sliderPartner').carousel(parseInt(indicatorNumber)); 
 
    }); 
 
    $("body").keyup(function(e) { 
 
    e.stopPropagation(); 
 
    if (e.keyCode == 37) { // left 
 
     $('#sliderPartner a.left').trigger('click'); 
 
    } else if (e.keyCode == 39) { // right 
 
     $('#sliderPartner a.right').trigger('click'); 
 
    } 
 
    }); 
 
});

爲什麼不能有你在哪一頁的全局變量保持跟蹤。

$(() => { 
    const MAX_PAGE = 10 // or however many pages 
    let pageNum = 0 

    goToPage = (newPage) => { 
     pageNum = Math.max(0, (Math.min(newPage, MAX_PAGE)) 
     doPageChange(pageNum) 
    } 
    next =() => { goToPage(pageNum + 1) } 
    prev =() => { goToPage(pageNum - 1) } 
})
