如何为 bxslider 启用键盘导航？

Question

我正在使用 bxslider 并添加了两个名为 #slider-next 和 #slider-prev 的按钮。鼠标点击事件工作得很好——当点击下一张幻灯片时，我的所有其他代码都被执行了。但我想用键盘箭头浏览幻灯片。那可能吗？如果是，如何？我试过了：

/* enable keyboard navigation */ 
        $(document).keyup(function (e) {
                if (e.keyCode == 37) { //left arrow
                    $( "#slider-prev" ).click(); 
                }
                if (e.keyCode == 39) { //right arrow
                    $( "#slider-next" ).click(); 
                }
         }); 

我的滑块上一个和滑块下一个单击功能的所有其他代码都已执行，但幻灯片的下一张或上一张图片没有出现。我错过了什么吗？

编辑： 我又看了一遍bxslider的纪录片，发现：

goToNextSlide 执行“下一张”幻灯片过渡

示例：滑块 = $('.bxslider').bxSlider(); slider.goToNextSlide();

goToPrevSlide 执行“Prev”幻灯片过渡

示例：滑块 = $('.bxslider').bxSlider(); slider.goToPrevSlide();

但是在修改我的 keyup 功能后，浏览器崩溃了:(

Answer 1

这是一个可以用于普通版 bxSlider 的示例：

    var slider = $("#yourSliderIDHere");

    slider.bxSlider({
      adaptiveHeight: true, // not needed for keyboard navigation, just for example
      onSliderLoad: function() {

          $("body").keydown(function(e) {
              if (e.keyCode == 37) { // left
                slider.goToPrevSlide();
              } else if(e.keyCode == 39) { // right
                slider.goToNextSlide();
              }
            });

      }
    });

找到解决方案 - 看here

编辑：

如果您在页面上有多个滑块但只有一个可见，并且您不想使用所有滑块转到下一张幻灯片但只有可见的滑块，请尝试以下操作：

if(el.is(':visible')){
    el.goToPrevSlide();
}

将下面的代码替换为您的 bxslider.js，即使您可以在第 1 行启用或禁用键盘键。 45.
