Bootstrap Carousel的多個輪播指標

Question

我正在嘗試用Bootstrap 3.2制作兩個輪播指標，事實證明，相對而言，我的JavaScript初學者比較難。 我嘗試添加兩個輪播指標列表項，但這僅對一組指標有效。 如何為一個輪播使用兩個輪播指示器？ 謝謝！

Answer 1

對於我來說，我的解決方案並不完美，但可能會對您有所幫助：)

我使用的功能：

$('#carousel-example-generic').on('slide.bs.carousel', function () {
 // stuffs
} 

當下一個輪播項目要更改時，將調用此操作。 然后，您可以添加自己的代碼，更改第二組不可更改的指標的CSS。

我的例子：

$('#carousel-example-generic').on('slide.bs.carousel', function () {

    var slide_number = $('.carousel-indicators_custom')
                      .children('.active')
                      .children('.losange').attr('data-slide-to');

    // here slide number need to be parseInt and you'll certainly need to add +1 value

    $('.carousel-indicators_custom-mobile>li').css('color', '#333');
    $('.carousel-indicators_custom-mobile').find('li[data-slide-to=' + slide_number +']').css('color', '#be1522');
    $('.dynamic_puce__text').html( $('.carousel-indicators_custom-mobile').find('li[data-slide-to=' + slide_number +']').html() );
  });

這有點難看，但這是一個開始，即使我確定他們是更好的選擇。
